Epdm track material

It can be used in all kind of surfaces: - running tracks,- football field, - playgrounds,- school yards, golf fields. .

          Ethylene Propylene Diene Monomer Rubber,also named as EPDM in short, is the polymer of ethylene and propylene. Large scale commercial production began in 1963 and the current overall global consumption of EFPM are 800,000 tons per year. EPDM is polyolefine - catergorised and has excellent performance of vulcanization and its gravity is the lowest among all rubbers.

The major properties of EPDM granules are as follows:

1. Excellent chemical stability: 

        a) Excellent ozone resistance: it doesn't crack during 2430 hours' testing in 100ppm ozone;       b) Excellent weatherproof: it is stable in sunny, moist and cold environment for a long time without cracking.        c) Excellent heat-resistance: it is stable in environment with temperature from 120°C to highest 150°C for a long time after it is added with anti-aging agent.

2. Good elasticity:

        It has good elasticity even at low temperature.

3. Vivid color:

    Our EPDM granules are all colored with pigments of famous brand to ensure color fastness and softness of the surface color the granule as well as to prevent the reflection of dazzling light. Colorful EPDM granules can be mixed together for use.

4. Made from EPDM rubber:

       All granules are well cut and sieved to ensure low dust, unanimous grain size and exact color. Different size, color and gel content are available on request.

5. EPDM content:

      EPDM content is precisely to be contained as per the customer's requirement.

6. Containing no hazardous material, non-toxic and odorless and safe.

7. Low heat absorbency for barefoot walking.

8. Economic and easy maintenance:

       No special maintenance under daily cleaning.

      With the above properties EPDM granules we manufacture are characteristic of ageing resistance, unfading and pulverization-resistance in exposure to ultraviolet, ozone and acid rain.

 

Quality Warranty :

        The strict quality-control system and testing procedures are enforced in manufacture of EPDM rubber to guarantee the unanimous color, hardness and gravity of all batches as well as in granulating process of EPDM rubber to guarantee the unanimous color fastness and grain size. In addition, testing of tensile strength, tearing strength, wear resistance as well as the accelerated weathering of EPDM granules is performed. Our products complies with IAAF, CAA and CNAS guidelines / requirements and are approved by Chinese Athletics Association-CAA and China National Accreditation Service for Conformity Assessment, Labosport-France and International Amateur Athletic Federation - IAAF
