Which production links will lead to poor silicone products?

Silica gel products are silicone rubber as raw material, because of its analytical chemical composition and physical structure, management decision it has excellent plasticity, super strong high tear tensile strength and other characteristics, is other raw materials can not be replaced. But we in the production and processing of silica gel products in the whole process has been met with production and processing of silica gel products become brittle, very easy to break, or the performance of silica gel products can not meet the requirements. In the end what links lead to silicone products bad? Kemet breaks it down for you:
1. Caused by silicone rubber raw materials
Silicone rubber raw materials themselves will also cause silica gel products become brittle, in general, silica gel products become brittle, very easy to destroy is due to the quality of the plastic itself is not qualified, tear tensile strength is not up to the requirements caused by. In order to better control the cost, some manufacturers of silica gel products will generally fill the raw materials with silica powder to control the cost. The final negative impact of such raw materials is that the products can not meet the quality requirements.
2, forming die temperature or curing time is not well controlled
The whole process of silica gel product forming to grasp the mold temperature or curing time, according to the continuous test, choose the best forming temperature and curing time can be avoided.
3. Secondary vulcanization
Secondary vulcanization, the air flow is not good or the temperature is too much can cause the brittle silicone products is very easy to destroy, which requires the operator to strictly control the temperature of secondary vulcanization, and the air flow geographical environment is reasonable.
