Silicone Sealing RingMany may be unfamiliar with the concept of shrinkage rate, so even when similar issues arise, many silicone sealant manufacturers are unsure of how to address it. Today, let's discuss the factors that can affect the shrinkage rate of silicone seals.
The main reasons affecting the shrinkage rate of silicone seal rings are:
The shrinkage rate of silicone seal ring products increases with the addition of rubber content in the vulcanized products.
As the hardness of the vulcanized products increases, the shrinkage rate of the silicone seal ring products becomes a saddle-shaped curve.
Silicone Sealing RingThe elongation rate increases with the addition of raw material injections for vulcanized products. When the raw material quality is between 5% to 10%, the elongation rate remains relatively stable.
Silicone materials with greater plasticity have a smaller shrinkage rate; compounds with higher hardness exhibit less shrinkage.
The more filling used, the shorter the shrinkage; the higher the content of resin, the greater the shrinkage.
In addition to the factors mentioned above that can cause silicone seal rings to shrink, do you know of any other reasons that might affect their shrinkage rate?
