Can high temperature silicone rubber sealing ring be made without secondary vulcanization?
No, only after secondary vulcanization can the vulcanization be thorough, the performance be stable, and the linear shrinkage change is not great, so as to ensure the sealing quality. If you don't carry out secondary vulcanization, it will continue to vulcanize slowly at room temperature for a long time, but your goods have been sold. We can't disregard quality for efficiency.
