Summary
The customized solution for silicone needs to be comprehensively considered and implemented from multiple aspects such as formula optimization, raw material selection, processing technology control, surface treatment and design optimization, material selection matching, and application environment adaptability in order to improve the durability of products. The implementation of these measures not only helps to improve the quality and performance of products,
How does the silicone customized solution improve product durability?
Formula optimization and raw material selection
Add antioxidants and light stabilizers:
Adding an appropriate amount of antioxidant to the silicone formula can effectively capture free radicals, slow down the oxidation reaction rate, and improve the thermal oxidative stability of silicone.
Adding UV absorbers or light shielding agents as light stabilizers can effectively absorb or reflect UV rays, protecting silicone from the effects of photoaging.
Choose high-quality base polymers:
The selection of basic polymers with high purity, low volatility and good stability is the basis for improving the aging resistance of silica gel.
Adjust crosslinking density:
Appropriately increasing the cross-linking density of silicone can improve its moisture and heat resistance as well as mechanical strength. However, it is important to avoid excessive cross-linking that can cause material brittleness.
2、 Processing technology control
Temperature control:
During the processing of silicone, strict control of heating temperature and cooling rate is necessary to avoid prolonged exposure to high temperatures and reduce the risk of thermal oxidative aging.
Optimization of molding process:
Adopting reasonable molding processes, such as injection molding, extrusion molding, etc., to ensure uniform stress distribution inside silicone products and reduce aging acceleration caused by stress concentration.
Post processing technology:
For example, heat treatment and aging pretreatment can further stabilize the structure of silica gel and improve its aging resistance.
