The Polymer Content of EPDM Granules Directly Affects The Price

EDPM, or Ethylene Propylene Diene Monomer (EPDM), is a terpolymer of ethylene, propylene, and a non-conjugated diene. EPDM's most important characteristics are its superior resistance to oxidation, ozone, and corrosion. As EPDM belongs to the polyolefin family, it has excellent vulcanization properties. Among all rubbers, EPDM has the lowest specific gravity. It can absorb large amounts of fillers and oils with minimal impact on its properties, thus allowing for the production of inexpensive rubber compounds.

EDPM plastic surface layers are mainly composed of a single-component adhesive and EDPM granules, typically consisting of two layers with a thickness of 15 mm or more. They are primarily used in outdoor activity areas such as kindergartens and parks, and can also be directly laid on concrete surfaces, saving significant foundation costs compared to traditional polyurethane running tracks. Its biggest advantages are its anti-slip properties and the fact that its colors and patterns can be customized to meet customer needs.

EDPM prices vary widely due to differences in the rubber content. The rubber content of EPDM rubber granules is typically 10%, 13%, 15%, or 20%. Higher rubber content generally indicates better quality and a higher price. Different rubber contents in EPDM also affect the performance of the surface. Higher rubber content results in greater durability, better flexibility, and less fading even under intense sunlight. Surfaces built with low rubber content lack sufficient EPDM virgin rubber to hold the auxiliary materials within the material. When exposed to wind and rain, these materials will weather into hollow, honeycomb-like granules, causing the surface to lose its original elasticity. Customers can choose the appropriate material ratio based on the specific usage and needs of their surface to customize a suitable surface.
