The Chinese name of EPDM is ethylene propylene diene monomer rubber, which is a terpolymer of ethylene, propylene and non-conjugated dienes. EPDM plastic court is mainly composed of EPDM colored rubber particles and black rubber bottom layer, which is a fixed track material.

EPDM rubber is a terpolymer of ethylene, propylene and non-conjugated dienes, which began commercial production in 1963. The annual global consumption is 800,000 tons. The most important feature of EPDM is its superior resistance to oxidation, ozone and corrosion. Since EPDM rubber belongs to the polyolefin family, it has excellent vulcanization properties. Among all rubbers, EPDM has the lowest specific gravity. It can absorb a large amount of fillers and oils without affecting the properties. Therefore, low-cost rubber compounds can be made.

Molecular structure and characteristics:

EPDM is a terpolymer of ethylene, propylene and non-conjugated dienes. Diene has a special structure, and only one of the two bonds can be copolymerized. The unsaturated double bond is mainly used as a crosslink. The other unsaturated will not become the main chain of the polymer, but only a side chain. The main polymer chain of EPDM is fully saturated. This property makes EPDM resistant to heat, light, oxygen, and especially ozone. EPDM is essentially non-polar, resistant to polar solutions and chemicals, has low water absorption, and has good insulation properties.

During the production process of EPDM, its properties can be adjusted by changing the number of three monomers, the ethylene-propylene ratio, the molecular weight and its distribution, and the method of vulcanization.

EPDM plastic has excellent performance and has the following characteristics:

1. Moderate elasticity: good elasticity and excellent shock absorption performance can provide good protection for the leg joints of athletes;

2. Strong wear resistance: can ensure the long-term stability of the pavement structure;

3. Anti-aging: will not fade or powder due to the influence of ultraviolet rays, ozone, wind and rain;

4. Impact resistance: strong elastic layer and buffer layer can absorb strong impact;

5. Good flatness: granular material is used when constructing EPDM plastic track, mechanical paving is adopted, the surface is flat, sun-proof and non-slip;

6. Various colors, simple foundation requirements, even poor foundation can be paved and water permeability is good.
