Fall Protection Granules

Fall protection granules are the critical component that determines whether a playground surface performs as a safety system or fails under impact. Our EPDM granules are manufactured using peroxide sulfidation technology, a sulfur-free cross-linking process that eliminates the risk of sulfide formation upon sunlight exposure. This means no odor, no environmental pollution, and no harm to the human body—properties that matter enormously when the end users are children. The molecular structure achieved through peroxide curing delivers tensile strength in the 4–7 MPa range and extends service life by more than three times compared to conventional sulfur-cured granules. We supply these granules to integrators, contractors, and playground operators worldwide, and we are happy to send free samples for your own testing and validation.

What Fall Protection Granules Solve for You

If you specify or install playground safety surfacing, you face a recurring set of problems: surfaces that fade or harden within a few seasons, granules that emit odor under intense sun, inconsistent color from batch to batch that ruins the visual finish, and impact performance that degrades faster than the warranty period. Peroxide-cured EPDM granules address these issues at the material level. The sulfur-free chemistry means the granules do not generate acidic byproducts when exposed to UV and heat, so the surface remains odor-free and the surrounding environment stays clean. The stable carbon-carbon cross-link network resists aging and keeps elasticity intact far longer than sulfur-cured alternatives, which directly protects your reputation on completed projects and reduces callbacks.

Applications and Climate Durability

Fall protection granules are used as the wearing course in wet-pour safety surfaces beneath and around playground equipment, where impact attenuation according to standards such as EN 1177 is required. They are also specified for multi-use games areas, fitness trails, outdoor gym flooring, and the top layer of prefabricated safety tiles. In artificial turf systems, EPDM infill provides dimensional stability and shock absorption without the odor issues associated with alternative infills.

Climate is where granule quality either proves itself or fails. In the Middle East and other high-UV regions, inferior granules chalk and fade within a single summer. Our peroxide-cured EPDM maintains color stability under prolonged UV exposure because the polymer backbone is inherently saturated and resistant to oxidative degradation. In cold climates, the granules retain flexibility at low temperatures, resisting embrittlement and cracking through freeze-thaw cycles. In tropical and high-rainfall regions, the non-porous, closed structure of the granules prevents water absorption, so the surface does not become waterlogged or lose impact performance when saturated. For coastal installations, the absence of sulfur means no risk of sulfide staining or corrosion in the presence of moisture and metal fixtures.

Frequently Asked Questions

Are these granules suitable for use in hot, high-UV climates?

Yes. The peroxide-cured EPDM structure provides inherent UV stability without relying solely on surface coatings. The polymer is saturated, meaning it lacks the double bonds that make sulfur-cured rubbers susceptible to ozone and UV attack. In practice, this translates to significantly slower color fade and less hardening over time in intense sun exposure.

Do the granules contain any sulfur or produce odor?

No sulfur is used in the curing process. Peroxide cross-linking creates direct carbon-carbon bonds between polymer chains, so there are no sulfur residues to react with sunlight, heat, or moisture. The result is an odorless granule that does not release sulfides into the environment or surrounding air.

What sizes are available for fall protection applications?

We produce 0.5–1.5 mm, 1–3 mm, 1–4 mm, 2–4 mm, and other custom particle size distributions. For wet-pour safety surfaces, 1–3 mm and 1–4 mm are common choices for the wearing course, while finer grades may be specified for specific texture requirements. We can adjust the grading curve to match your binder system and application method.

Can you match a specific color for our project?

Yes. We support RAL and Pantone color matching, as well as customer sample matching. Whether you need a standard playground color or a custom shade for a branded installation, we produce to your reference with tight batch-to-batch consistency.

What is the typical lead time and minimum order?

Lead times depend on specification and volume, but our production capacity and raw material inventory allow us to move quickly on both sample orders and full container loads. We support LCL and FCL shipments. Minimum order quantities are flexible—contact us with your project requirement and we will confirm the most practical arrangement.

Do you supply the binder or only the granules?

We manufacture EPDM granules exclusively. We do not mix or install systems. This focus means our technical support is directed entirely at helping you get the best performance from the granule component, and we can recommend compatible binder chemistries based on our experience with integrators worldwide.

Why Choose Us

We have spent over 25 years doing one thing: producing EPDM granules. We do not install, we do not contract, and we do not split our attention between materials and labor. That focus shows in the consistency of our output and the depth of our process knowledge. Our peroxide sulfidation line is run by operators who understand cross-link density and its relationship to tensile strength and aging resistance. We export globally and are accustomed to the documentation, packaging, and specification requirements of buyers across different regions. OEM, ODM, and private label arrangements are standard practice for us. We support custom packaging, color combinations, and particle size blends. Our quality control tracks color consistency and polymer performance batch by batch, so what arrives in your warehouse matches what you approved in the sample.
