Experiment purpose: under the same conditions, the performance of the cooling rubber tube of test each group.
EPDM (ethylene propylene diene rubber) is most excellent elastomeric material, and EPDM is also referred to as saturated rubber, with unsaturated rubber
Glue such as NR (natural rubber), NBR (butyronitrile rubber) etc. are compared, and chemical stability and thermal stability are higher, cold for radiator
But when liquid glue pipe, EPDM had not only had good heat resistance, resistance to ag(e)ing and ozone resistance, but also had excellent resistance to coolant liquid and change
Stability is learned, its structure of TATD is similar to other thiuram disulfides, and only it contains the chain alkyl of high molecular weight, point
Son amount is higher than 2~4 times of other thiuram-disulfides, and since its molecular weight is high, volatility is very low, and Asia is not generated in sulfidation
Nitramine.Its outstanding advantages are to can be shortened vulcanization time not sacrifice scorch safety, dissolution of the TATD in ethylene-propylene diene copolymer
About 5 times of other promotors are spent, especially suitable for ethylene propylene diene rubber product,
As the above experimental result table it is found that seal rubber properties obtained by the present invention be superior to it is common on the market
The performance of seal rubber.
