Why Grinding Plastic Matters in Rotomolding

Sun, 10 Aug 2025 14:32:45 GMT

Rotomolding (short for rotational molding) is a process used to make hollow plastic parts — like tanks, bins, playground equipment, and coolers. Plastic powder is added to a mold, which is then slowly heated and rotated. The powder melts, coats the inside of the mold, and forms into the final shape.

But not just any plastic can be used in this process. It needs to be ground into a fine, even powder first — and that’s where Midwest Elastomers comes in.

We specialize in grinding plastic resins to the right consistency for rotomolding. Here’s why that step is so important:

1. Better Flow in the Mold

Powdered plastic spreads more evenly in the mold than pellets or chunks. That means smoother surfaces, consistent wall thickness, and fewer defects.

2. More Even Melting

Fine powder melts faster and more evenly. This helps prevent issues like air bubbles, unmelted spots, or uneven finishes.

3. More Control Over the Process

With consistent powder, it’s easier to control heating, cooling, and cycle times — which helps make parts that come out the same every time.

4. Fits Standard Rotomolding Equipment

Most rotomolding machines are designed to use powder, not pellets. Grinding ensures your material is compatible and ready to go.

5. Even Additive Mixing

Need color, UV resistance, or other additives? Ground plastic mixes better, which gives you a more uniform final product.

6. Supports Recycling

We can grind scrap or post-consumer plastic so it can be reused — reducing waste and helping you meet sustainability goals.

Grinding isn’t just an extra step — it’s a key part of making sure your rotomolded parts turn out right. It improves quality, consistency, and efficiency.

Why Safety Surfacing Outperforms Stone, Wood Mulch, and Other Traditional Materials

Fri, 25 Jul 2025 19:25:27 GMT

When it comes to playgrounds, athletic facilities, landscaping, or public spaces, choosing the right surface material can make all the difference in safety, performance, and durability. While stone and wood mulch have been longstanding choices, advancements in rubber safety surfacing—especially those made with high-quality ground rubber from Midwest Elastomers—offer a smarter, safer, and more sustainable solution.

As expectations grow for safer and more inclusive environments, many municipalities, schools, and contractors are making the switch to rubber-based safety surfacing. But what exactly makes it the superior option?

Let’s take a closer look at how rubber safety surfacing compares to traditional materials like stone and mulch, and why it’s quickly becoming the preferred choice across industries.

1. Superior Impact Absorption

Rubber safety surfacing is specifically engineered to cushion falls, minimizing the risk of serious injuries. In playgrounds, athletic areas, and recreational spaces, this is a top priority. Traditional materials like stone or wood mulch don’t provide consistent shock absorption—especially after settling or displacement.

Rubber surfacing meets or exceeds ASTM F1292 standards for impact attenuation.
Mulch and gravel may meet initial safety standards but quickly degrade and shift, requiring frequent attention to maintain safety.

2. Consistent and Low-Maintenance Coverage

Loose-fill materials like mulch and gravel shift with use, weather, and time. This leads to uneven coverage, tripping hazards, and frequent maintenance. Rubber safety surfacing, on the other hand, remains stable and intact with minimal upkeep.

Rubber surfacing retains even coverage year-round.
Mulch and stone require regular raking, leveling, and replenishing.

3. Durability and Longevity

Rubber surfacing holds up under heavy use and all weather conditions. It resists cracking, compacting, erosion, and pest damage. By contrast, wood mulch breaks down and rots, and gravel often washes away or embeds into surrounding soil.

Midwest Elastomers' ground rubber products are engineered for durability and long-term performance.
Traditional materials have shorter lifespans and higher maintenance costs over time.

4. ADA Accessibility

Inclusive design starts at the ground level. Rubber safety surfacing provides smooth, even surfaces that are easy for individuals using wheelchairs, walkers, or strollers to navigate. Loose-fill alternatives often make accessibility difficult or impossible.

Rubber surfacing supports ADA compliance and universal access.
Mulch and gravel create unstable surfaces that hinder mobility.

5. Environmental Responsibility

Using recycled rubber in surfacing applications not only keeps waste out of landfills, but also reduces the need for virgin materials. Midwest Elastomers specializes in converting post-consumer and post-industrial rubber into high-quality products that contribute to a circular economy.

Rubber surfacing repurposes waste into a valuable, sustainable product.
Wood mulch contributes to deforestation and typically has a much shorter lifespan.

6. Cost-Effective Over Time

While rubber surfacing may involve a higher initial investment, it offers substantial savings in the long run due to lower maintenance, longer life, and reduced liability. The total cost of ownership is often lower compared to constantly replenishing and maintaining stone or mulch.

Lower lifecycle costs make rubber surfacing a smart long-term investment.
Traditional materials come with recurring expenses for upkeep, labor, and replacement.

At Midwest Elastomers, we’re proud to supply premium ground rubber that enhances safety, performance, and sustainability in surfacing applications across the country. Our materials are manufactured to the highest standards and are trusted by surfacing companies, installers, and contractors nationwide.

Using Ground Rubber in Brake Pad Friction Materials

Mon, 14 Jul 2025 15:20:57 GMT

Brake pads are critical for vehicle safety, converting kinetic energy into thermal energy through friction to slow or stop a vehicle. At Midwest Elastomers, we specialize in providing high-quality ground recycled rubber materials that enhance the performance of brake pad friction materials. This blog explores how ground rubber contributes to brake pad formulations, offering a balance of performance, sustainability, and cost-effectiveness.

The Role of Ground Rubber in Brake Pads

Ground rubber, derived from post-industrial rubber sources, is increasingly used in brake pad friction materials, particularly in non-asbestos organic (NAO) formulations. It serves multiple purposes:

Noise and Vibration Dampening : Ground rubber acts as a lubricant and filler, reducing brake noise and vibrations, which enhances driver comfort. Its elasticity helps absorb vibrations, mitigating the squealing often associated with braking.
Cost-Effectiveness : Incorporating ground rubber lowers production costs compared to other materials like Kevlar or ceramic fibers, making it an economical choice for manufacturers.
Environmental Benefits : Using recycled ground rubber supports sustainability by repurposing waste materials, reducing landfill use, and aligning with eco-friendly manufacturing trends.
Friction Modulation : Ground rubber contributes to a softer, smoother braking feel, ideal for daily driving conditions. It helps maintain a moderate coefficient of friction (typically 0.3–0.5), preventing wheel lockup while ensuring effective stopping power.

How Ground Rubber Enhances Brake Pad Performance

Brake pads rely on a complex blend of materials, including binders (e.g., phenolic resin), fibers, fillers, and friction modifiers. Ground rubber, often used as a filler or friction modifier, complements these components:

Wear Characteristics : Organic brake pads with ground rubber wear faster than semi-metallic or ceramic pads, but they are gentler on brake rotors, extending rotor lifespan and reducing maintenance costs.
Thermal Stability : While ground rubber has lower heat resistance compared to metallic or ceramic materials, it performs well in low-to-moderate temperature ranges (up to 250°C), making it suitable for standard passenger vehicles.
Dust Reduction : Ground rubber in NAO pads produces less visible brake dust compared to semi-metallic pads, improving wheel aesthetics and reducing cleaning needs

Midwest Elastomers’ Contribution

At Midwest Elastomers, we provide finely ground recycled rubber particles (down to 300 μm or smaller) tailored for brake pad manufacturing. Our advanced grinding processes ensure consistent particle size and quality, which are critical for achieving uniform friction properties and minimizing wear. By offering customizable ground rubber solutions, we help manufacturers optimize formulations for specific vehicle types and driving conditions.

Sustainability and Innovation

The use of ground recycled rubber aligns with the automotive industry’s shift toward eco-friendly materials. By incorporating recycled rubber, manufacturers can reduce the environmental impact of brake pad production while meeting regulatory requirements, such as those limiting copper content due to its impact on aquatic life. Additionally, research into natural fibers and waste materials highlights the potential for ground rubber to be part of innovative, sustainable friction material formulations.

Challenges and Considerations

While ground rubber offers numerous benefits, it has limitations:

Performance Limits : Ground rubber is less suited for high-performance vehicles or extreme conditions due to its lower thermal stability and faster wear rate.
Fade and Glazing : Under high temperatures, organic pads with ground rubber may experience fading (temporary loss of braking power) or glazing (hardening of the pad surface), reducing effectiveness.To address these, manufacturers often blend ground rubber with other materials, such as ceramic or metallic fibers, to balance performance and durability.

Ground rubber plays a vital role in modern brake pad friction materials, offering a cost-effective, sustainable, and performance-enhancing solution for NAO formulations.

Boosting Productivity Without Breaking the Planet

Sun, 04 May 2025 23:48:56 GMT

Overconsumption is costing us more than we think.

Mindless production. Disposable systems. A constant race to scale—no matter the toll.

It’s not just hurting the planet. It’s weakening supply chains, overloading teams, and accelerating burnout across industries.

Mountains of waste. Strained supply chains. Teams expected to deliver more with fewer resources—while the planet absorbs the cost.

It’s a cycle that’s become business as usual.

But what if business as usual isn’t good enough anymore?

What if there’s a way to move faster and smarter—to boost performance without burning through people or the planet?

That’s the question we asked.

And in a quiet corner of Ohio, we found the answer.

Why It Matters in 2025—and Beyond

Here’s the reality:

Over 300 million tons of plastic are produced every year
Rubber waste alone contributes to 1.5 billion tons of landfill buildup
These materials leach toxins into soil, water, and air for decades

The traditional approach? Send it to landfill, replace it with virgin material, repeat.

The impact? Sky-high costs, unpredictable supply chains, and irreversible damage to the planet

But rubber doesn’t have to rot.

It can be reused, reshaped, and reintegrated into sustainable supply chains.

Sustainability Isn’t a Side Effect—It’s the Strategy

We don’t make green goals after the fact. We include sustainability into every process , because we know: it’s not a cost—it’s a competitive edge.

Here’s how:

Tolling services : Clients send us their waste; we grind and return it as reusable material
Internal recycling : We reduce landfill output by reprocessing our own system’s scrap
Material repurposing : Our products are designed for longer life cycles, reducing the need for replacements

In our Sports Surfacing Division , we transform recycled rubber into:

Black EPDM & SBR granules
Shock-absorbing rubber mulch (various colors available)
Rubber buffings for safety surfaces

These surfaces outperform traditional materials—not just in resilience, but in environmental impact.

We don’t settle for “doing less harm.”
We aim to do more good .

Productivity, Reimagined with Precision

At MEI, we’ve left the “more, faster, cheaper” mindset behind—because real progress demands smarter, cleaner, and more sustainable thinking.

Today’s world demands a better equation: efficient systems, minimal waste, and scalable impact.

We’ve invested in advanced cryogenic and ambient grinding technologies—not just to process rubber, but to elevate it. Our methods aren’t just cleaner—they’re smarter.

Here’s how it works:
We process post-industrial rubber scrap, including:

Butyl
Natural Rubber
Fluoroelastomer (FKM)
SBR
Nitrile
Neoprene
EPDM

We convert rubber into high-performance granules & powders—ranging from .5-1.5mm to 120 mesh—that help clients:

Cut material costs
Streamline production
Improve output consistency

Backed by Science. Built for Scale.

Our cryogenic grinding process , powered by liquid nitrogen, yields finer, more uniform particles— using less energy than traditional methods. That translates into:

Up to 30% productivity gains
Reduced environmental impact
ISO 9001:2015-certified quality

We don’t just chase efficiency. We design for it.

Our quality assurance isn’t a department—it’s a culture.

Every MEI team member is trained by our “ Quality is the Cornerstone of MEI ” policy.

This isn’t theory. It’s a proven model—and it’s built to grow with you.

"The greatest threat to our planet is the belief that someone else will save it."
