Causes of Wholesale rubber sealing ring whitening

2022-04-24

1. Wholesale rubber sealing ringraw material quality
Due to the different production materials of the sealing ring, different production methods, different technologies, and different batches, the raw materials have great changes; also due to the composition technology of raw rubber: polymerization temperature, catalyst, composition monomers, etc. Differences lead to differences in solubility. Differences; physical properties and other changes occur at the same time.
2. Wholesale rubber sealing ring raw material aging
The aging of the raw materials of the sealing ring mostly leads to the destruction of the intact and balanced network structure of the vulcanizate, which also destroys the chemical or physical combination of various compounding agents in the rubber system and the raw rubber molecules and compounding agents, reducing the compounding agent. Solubility in Wholesale rubber sealing ring systems.


3. Poor storage conditions of Wholesale rubber sealing ring raw materials
The solubility of the compounding agent in rubber generally rises and falls with the rise and fall of the temperature; the pressure of the rubber during storage, the humidity of the surrounding air and the time also affect the solubility of the compounding agent. The compounding agent will form a crystal nucleus, which will be precipitated on the surface of the rubber sealing ring to form a bloom.
