First of all, we have to clear the hydraulic seal (
Is widely used to the chemical industry, the industry of the sealing ring, prevent leakage along the axis of work medium to reverse invades the body internal and external dust outside shell.
To analyze factors influencing the tensile strength of seal: 1, small molecular weight of rubber tensile strength increases with the increase of molecular weight and;
2, narrow molecular weight distribution of rubber seals
tensile strength is higher;
3, the increase of crystallinity of rubber seals tensile strength increases;
4, on the main chain polarity state, the tensile strength increases with the increase of intermolecular forces;
After 5, rubber molecule chain orientation, parallel to the direction of the tensile strength increased, the tensile strength of the vertical drop;
6, the tensile strength decreases with the increase of the cross-linking bond energy, along with the increase of crosslinking density of occurrence peak;
7, hydraulic seal material surface oxygen groups, its high tensile strength, tear strength, elongation,
8, packing of particles is small, large surface area, surface activity, the reinforcement effect is good, also can improve the tensile strength by material blending;
9, the dosage of softener beyond five copies, will reduce the tensile strength of the vulcanizates.

Owing to its custom rubber seals and custom rubber seals benefits, has become a buzzword in the custom rubber seals market.
We would appreciate your immediate attention to rubber seals.
is something that has been around for a few decades now, enjoying it's heyday back in the custom rubber seals.
custom rubber seals rubber seals is characterized by various advantages, such as custom rubber seals, custom rubber seals and custom rubber seals, which is not the case with other rubber seals.
Ruichen Sealing Co., Ltd. can promise that rubber seals is one of the best products sold in the worldwide market at present.
