Rubber Granules for Sports Fields

Professional EPDM Granule Manufacturing for Global Sports Surface Applications

Our EPDM granules deliver exceptional weather resistance and are produced using peroxide vulcanization—a sulfur-free process that eliminates odor, prevents sulfide formation under sunlight exposure, and ensures no harm to the human body or the environment. As one of the highest-quality and most cost-effective EPDM granule manufacturers in China and beyond, we focus exclusively on granule production, not installation. This allows us to dedicate our full expertise to what matters most to buyers: consistent quality, color stability, and reliable supply. We welcome requests for free samples so you can verify performance before committing to an order.

What EPDM Granules Solve for Sports Surface Professionals

If you specify, purchase, or install sports surfaces, you face a recurring set of risks: granules that fade within a season, surfaces that harden or become sticky under heat, unpleasant odors near playgrounds, and inconsistent color from batch to batch that ruins the finished look. Sulfur-cured granules are particularly vulnerable—under UV and high temperatures, residual sulfur can oxidize and generate sulfates, leading to discoloration and odor . Peroxide-cured EPDM addresses this at the molecular level. The carbon-carbon bonds formed during peroxide vulcanization are more stable than the carbon-sulfur bonds in conventional sulfur-cured systems, which is why independent studies show peroxide-cured EPDM retains significantly better tensile strength and elongation after accelerated weathering . For buyers, this translates into surfaces that stay looking right and performing right for longer, with fewer complaints and lower replacement frequency.

Applications and Advantages Across Global Climates

EPDM granules are a versatile material used across a broad spectrum of sports and leisure surfaces. They serve as infill in artificial turf systems, providing the resilience and shock absorption that modern pitches require . They are the colored top layer in running tracks, multi-purpose courts, tennis courts, and playground safety surfaces, where their elasticity and UV stability are essential . They also appear in wet-pour play surfaces, rubber tiles, and outdoor fitness areas.

What makes EPDM uniquely suited to these applications is its saturated hydrocarbon backbone. This molecular structure gives EPDM inherent resistance to ozone, oxygen, UV radiation, and temperature extremes—properties that have made it a preferred material for sports surfaces for decades . For buyers sourcing from different regions, this matters in practical terms. In hot climates with intense sunlight, peroxide-cured EPDM resists the thermal degradation and color fade that plague lesser materials. In cold climates, it remains flexible without cracking. In regions with heavy rainfall and high humidity, EPDM’s non-polar structure limits water absorption, helping surfaces drain and recover quickly. From the heat of the Middle East to the wet winters of Northern Europe, the material’s performance remains consistent.

Frequently Asked Questions

What is the difference between peroxide-cured and sulfur-cured EPDM?

Peroxide curing creates carbon-carbon crosslinks between polymer chains, while sulfur curing creates carbon-sulfur bonds. The C-C bond has higher bond energy, which gives peroxide-cured EPDM superior resistance to heat aging and UV degradation . Crucially for odor-sensitive applications like playgrounds and indoor facilities, peroxide curing leaves no sulfur in the compound, so no sulfides can form when the granules are exposed to sunlight.

Can you customize granule size and color for our project?

Yes. We support custom particle sizes including 0.5–1.5 mm, 1–3 mm, 1–4 mm, 2–4 mm, and other specifications upon request. For color, we offer RAL and Pantone matching, as well as custom color development based on your samples. We also support color combinations to achieve the exact visual effect your project requires.

Do your granules perform well in both extremely hot and cold climates?

Our EPDM granules are formulated for global climate adaptability. The peroxide-cured structure provides stable elasticity across a wide temperature range, resisting hardening in cold conditions and maintaining structural integrity under prolonged heat exposure. For buyers in tropical or desert climates, the UV stability and heat resistance are particularly advantageous.

What is your minimum order quantity and lead time?

We maintain flexible MOQ policies to accommodate both trial orders and large-scale projects. With 25+ years of production experience and full production lines, we can complete orders quickly and maintain stable supply for repeat customers. Contact us with your volume requirements for a specific timeline.

Do you offer OEM and private label services?

Yes. We support OEM, ODM, and private label arrangements. Whether you need your brand on the packaging or a fully customized product formulation, we can accommodate. We also support custom packaging configurations and both full-container and LCL shipments.

How do you ensure color consistency across batches?

Color consistency is a core focus of our quality control. We use controlled pigment systems and rigorous batch verification to maintain high color uniformity. For long-term projects or multi-phase installations, we can retain reference samples to ensure subsequent batches match the original specification.

What is the tensile strength and elasticity of your granules?

Our peroxide-cured EPDM achieves tensile strength in the range of 4–7 MPa, with elasticity and tensile performance 2–3 times higher than conventional products. The molecular stability from peroxide curing also extends service life significantly compared to sulfur-cured alternatives .

Are free samples available for testing?

Yes. We encourage buyers to test before ordering. We provide free samples so you can evaluate granule size, color, elasticity, and odor for yourself. This is the most reliable way to confirm the material meets your project standards.

Why Choose Us

We are a specialist manufacturer. EPDM granules are not a side business for us—they are the only thing we produce. That focus is reflected in our 25+ years of industry experience and our investment in full production lines dedicated solely to granule manufacturing. We do not take on installation contracts, which means our entire operation is oriented toward one goal: producing granules that installers and buyers can depend on.

Our global export experience means we understand the practical requirements of buyers across different markets—documentation, packaging standards, shipping logistics, and the quality expectations that vary by region. We support OEM, ODM, and private label customers, and we accommodate RAL, Pantone, and sample-based color matching. Particle size customization covers everything from fine 0.5–1.5 mm granules to larger 2–4 mm specifications, with special sizes available on request.

Because we use peroxide vulcanization, our granules contain no sulfur. This is not a minor detail. It is the foundation of several performance advantages: no odor, no sulfide formation under UV exposure, enhanced thermal stability, and a molecular structure that supports a service life extended by a factor of three or more. The tensile strength reaches 4–7 MPa, property retention is improved by over five times, and the material shows excellent flame retardancy at Level 1. The granules have low bulk density and a pronounced angular, three-dimensional shape that contributes to good coverage and interlock in surface systems.

We maintain strict quality control throughout production, with particular attention to color consistency and UV stability. Whether you are sourcing for a single project or establishing a long-term supply relationship, we aim to be the manufacturer you do not need to second-guess.
