EPDM particles are made of calcium powder, toner, rubber oil, ethylene propylene diene monomer and other auxiliary materials. After fusion reaction at high temperature, EPDM particles are vulcanized and shaped. After being broken by a crusher, they are screened out by different types of mesh screens with different pore spacing to produce granular plastics with different sizes and specifications. After mixing with glue in a fixed proportion, EPDM particles are spread on the ground. After the glue is cured, a layer of elastic plastic ground is formed We generally call it EPDM plastic ground. EPDM plastic ground has the characteristics of super abrasion resistance, high elasticity, corrosion resistance, aging resistance, environmental protection, etc. it is often used for the pavement of children's playgrounds, kindergartens and school playgrounds.
