Polyurethane Binder & EPDM Granules: The Ideal Combination for Playground Safety Surfacing
EPDM Rubber Granules: Engineered for Performance and Longevity
Our EPDM (Ethylene Propylene Diene Monomer) granules are premium, vulcanized rubber particles engineered to deliver unparalleled performance in synthetic surfacing. They form the durable, elastic, and colorful wearing course in a permanently elastic system when bound with polyurethane

FAQ:
Q1: What is the coverage rate?
A: Coverage depends on grain size and layer thickness. For a 10mm thick layer, 1-3mm granules require approx. 18 kg/m². Contact us for an exact calculation.
Q2: Can EPDM granules be applied over existing concrete?
A: Yes, provided the concrete is sound, clean, free of contaminants, and has adequate drainage. A primer may be required.
Q3: Do you offer global shipping and technical support?
A: EN: Yes, we export worldwide and offer remote technical guidance for installation. Bulk and container orders are welcome.
