Versatile EPDM Granules for Elasticity Safety and Durability
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.

Q1: What is the difference between EPDM and SBR granules?
A: EPDM is a virgin, synthetic rubber primarily valued for its exceptional durability, color stability, and UV resistance. It is used as the top, visible layer for high-quality, long-lasting, and aesthetically pleasing surfaces. SBR is a recycled rubber from tires. It is a cost-effective material primarily used as an elastic infill in the lower layer of a system to provide shock absorption, but it offers limited color options and will fade over time when exposed to sunlight.
Q2: How long does the color last?
A: Our EPDM granules are manufactured with high-quality, inorganic pigments that are UV-stable. Under normal weather conditions, they will retain their vibrant color for over 8 years without significant fading. For projects in areas with extreme, direct sunlight, some gradual fading may occur after this period, but the integrity of the surface remains intact.
Q3: Is this product safe for children and pets?
A: Absolutely. Our EPDM granules are non-toxic, heavy metal-free, and lead-free, making them completely safe for children and pets. They are also chemically stable and do not release harmful substances, even in high temperatures.
Q4: Can I use EPDM granules for a DIY project?
A: While it is possible, we highly recommend professional installation for any area larger than a few square meters or for safety-critical applications like playgrounds. Proper installation requires specific tools and expertise to ensure the correct binder ratio, even coverage, and long-term durability. We can supply detailed installation guides upon request.
