Transparent silicone products normally take a few years also won't yellow, is what reason can cause such a difference?
Technical personnel take everyone to understand why why yellow transparent silicone.
1, vulcanizing agent: ordinary don't fight yellow vulcanizing agent, used in some can be used for the color is deep or to request is not high color of silicone products.
Resistance to yellow vulcanizing agent used in demand revealed, shallow color is gorgeous, and the color request higher commodity.
2, technical aspects: bright silicone product in molding, led lit silicone product color yellow after forming the main questions are: mold temperature is too high;
Curing time is too long.
3, the poor quality of material itself, resistance to yellow vulcanizing agent is added in the gel, but after the molding is still looks yellow transparent silicone goods, that perhaps the material's resistance to yellow to bad, about poor material yellow resistance material is directly refueling.
Though silicone product has excellent weather resistance and aging resistance, but because of various reasons, also will appear this kind of phenomenon of yellow, in order to avoid this situation, to choose vulcanizing agent according to the requirement, technology is the control of mold temperature and curing time, the material aspect should pay attention to the material's resistance to yellow, can be made of transparent silicone products.
