The materials such as dirt, empty gas and water are acted on into sealing system, and the cost of material is low, reduces greatly product material cost.
Ethylene propylene diene rubber main chain is made up of the saturated hydrocarbons of chemical stabilization, containing unsaturated double-bond only in side chain, therefore base
Belong to kind of a saturation type rubber on this, due to nonpolarity substituent group in molecular structure, intermolecular cohesive energy is low, thus strand can compared with
The chemical constitution of compliance, EP rubbers is kept to make its vulcanized article that there is unique performance within the scope of wide temperature.Ternary second
Third rubber is very big in the application of weather strip for automobile field, and the main of EP rubbers has the disadvantage that curingprocess rate is slow,
, by butadiene and cinnamic copolymer, with wearability, anti-aging property, curingprocess rate is fast for butadiene-styrene rubber, by
Relatively low in its elasticity, resistance to flexion, tear resistance are poor, in weather strip for automobile field using fewer.
EPDM material properties domestic at present are unstable, mostly dependence on import EPDM.So that the cost of weather strip for automobile compared with
Height, existing EPDM costs are in about 22 yuan/more than KG.The maximum general purpose synthetic rubber of butadiene-styrene rubber current production rate, domestic production
Butadiene-styrene rubber comparative maturity, about 12 yuan/KG of price, if a combination of the two, can solve current weather strip for automobile material cost
