Although silicone products have various advantages, they will age after a long time of use. Then why do silicone products age? Let's briefly discuss this issue.
The viscosity of silica gel is higher than many others, but silica gel, like other rubbers, will also experience aging. Due to the rupture of the internal molecular chain, the performance of silica gel has changed greatly.
For rubber and plastic products, the most harmful thing for silicone products is ultraviolet light. Ultraviolet rays can directly cause the rupture of rubber molecular chains. This is because rubber and plastic products and silicone products can absorb light energy to produce free molecules in the rubber.
