EPDM Has Five Advantages:

1. The density of raw rubber is only 0.86-0.90kg/m3, which is the lightest common rubber; And it can fill a lot to reduce the cost of rubber.

2. Excellent aging resistance, weather resistance, ozone resistance, sunlight resistance, heat resistance, water resistance, water vapor resistance, UV resistance, radiation resistance and other aging properties. EPDM can act as a high molecular antioxidant or antioxidant when used with other unsaturated diene rubbers such as NR, SBR, Br, NBR, Cr, etc.

3. Excellent resistance to chemicals, acid, alkali, detergent, animal and vegetable oil, alcohol, ketone, etc; Excellent resistance to water, super hot water and steam; Resistance to polar oil.

4. Excellent insulation performance, volume resistivity 1016q · cm, breakdown voltage 30-40mv / m, dielectric constant (1kHz, 20 ℃) 2.27.

5. It can be used in a wide range of temperature. The minimum temperature is - 40 ~ - 60 ℃. It can be used at 130 ℃ for a long time.

In the application of modified plastics, EPDM is blended with PP, such as the spray free material of giselon, PP / EPDM + T20, which is used in the exterior decoration of automobile side skirt and bumper guard.

Customized EPDM and silicone parts air and water pumps process 

1. Provide us a 3D drawing with detailed require ( material, color, hardness, tolerance etc. )

2. We check the drawing if workable or not ,check the tolerance or trimming control 

3. Quotation based on quantity

4. Sample molding and provide sample for approval 

5. Mass production after sample  approved 

6. If sample do not pass , we make solution for improvement.
