Features of EPDM of Double Sphere Rubber Joint
EPDM double sphere rubber joint made of ethylene and Propylene Copolymerization with the backbone not containing double bond. Therefore, it’s of great heat resistance, aging resistance, resilience, insulation performance, stability, ozone resistance and low temperature resistance, but it cannot be vulcanized by sulfur. To solve this problem, in the main chain is added into a small amount of the third ingredients with double bonds, and it’s then named EPDM. It’s excellent in polar solvents resistance such as alcohols, ketone, ethylene glycol and phosphate ester hydraulic oil.
Temperature range: -55 to 125 C, the organic peroxide can be high to 150.
Advantages:
Good climate and ozone resistance
Excellent resistance to water and chemicals
Applicable to alcohols and ketones
High temperature vapor, low gas permeability
Seal for high temperature water vapor environment
Bathroom equipment seal or parts
Brake (brake) system of rubber parts
Radiator (car tank) seal
Defect:
It is not recommended for food use or exposure to aromatic hydrocarbons.
Applicable medium:
Hot water and steam
Ethylene glycol base brake fluid, silicone brake oil
Variety of organic acids and inorganic acids
Detergent, soda, potassium hydroxide
Phosphate ester hydraulic oil
Silicone oil and silicone ester
A variety of polar solvents (alcohols, ketones, esters)
Not suitable medium:
Mineral oil, fuel
