Common problems in the production of rubber O-rings

Apr 28, 2018

Reasons for the brittleness and cracking of the hydraulic O-ring vulcanization process:

1. The vulcanization system is adjusted. The formulation uses high ethylene or oil-filled rubber, plus some coupling agent, to activate it.

2, the amount of curing agent exceeded, the degree of vulcanization is too deep. The amount of curing agent.

3, vulcanization temperature is too high, curing time is too long. Cooling to extend curing time.

4, product mold, whether there is uneven wall bias caused by force.
