2, the use of silicone rubber hydroxyl content is too much, high temperature aging.
3, the amount of catalyst used, or the quality of the catalyst used is not qualified, resulting in high temperature resistant silicone tube yellowing phenomenon.
4. Adding too much internal release agent and zinc stearate, the iron content in it is too high, resulting in yellowing of the surface of the high temperature resistant silicone tube
