Name: Three composite sealing strip

Material: EPDM compact + sponge + steel strip

Uses: automotive seals, refrigerated truck seals, container seals, mechanical seals, cabinet seals

Features: low opening force (80% smaller than traditional rubber strip opening force)

          Excellent sealing effect (50% better than traditional rubber sealing effect)

          Easy to install (saving the aluminum alloy bead directly installed and fixed)

1, aging resistance. The sealing strip has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical properties, oil filling and room temperature fluidity. It can be used for a long time at 120 ° C, and can be used temporarily or intermittently at 150-200 ° C. Under the condition of ozone concentration of 50pphm and stretching of 30%, it can be cracked for more than 150h.

2, corrosion resistance. EPDM seals have good resistance to various polar chemicals such as alcohols, acids, bases, oxidants, refrigerants, detergents, animal and vegetable oils, ketones and fats.

3, water vapor resistance. EPDM seals have excellent water vapor resistance and are superior to their heat resistance. In the superheated steam at 230 °C, there is no change in appearance after nearly 100h.

4, resistant to superheated water. Ethylene-propylene rubber has good resistance to superheated water. After soaking for 15 months in 125°C superheated water, the mechanical properties change very little, and the volume expansion ratio is only 0.3%.

5, good flexibility. The EPDM seal has good elasticity and elongation.
