Some people may encounter rubber sealing ring cracking, like nitrile rubber sealing ring why there are cracks?
Here's why:
1, rubber sealing ring production problems:
(1) Formula design caused by less oil or resin or vulcanization temperature is too high, poor liquidity and other reasons!
(2) The void caused by bad exhaust occurs in the product during manufacturing
(3) When the raw material is too thick, it also causes cracks.
2. During the use of rubber seals: high temperature and exposure to sunlight in the air will cause aging and cracking of nitrile rubber.
Suggestion:
(1) Processing AIDS (stearic acid, paraffin or polymer wax) should be appropriately increased!
(2) Add 2-5 parts of the operating oil properly!
(3) The vulcanization temperature is appropriate, according to the rheometer selection!
(4) re-adjust the parameters in the processed species (such as temperature, exhaust gas, raw material thickness, etc.)
