How many degrees of high temperature silicone mold resistance?

Mold silica gel because of its superior characteristics, it is used in the production of a variety of materials, such as cement, gypsum, resin, plastic, rubber, alloy, soap, candles, food and so on. But silica gel simply has tear resistance and low shrinkage is not enough, but also need acid and alkali resistance aging, high temperature and low temperature resistance. Shenzhen Kaimet silica gel Xiaobian to share this period, how much can mold silica gel?
For temperature, it can be divided into mold silica gel liquid state and forming state. For example, Kemet HT-98 series plus molding liquid silica gel, curing ratio of 1:1, can be room temperature curing or heating fast curing, heating 120 degrees about 20-30 minutes curing. After forming the highest temperature 300-400 degrees (instant). Normal turning a variety of resin, plastic and other exothermic materials are no problem. The second is the low temperature resistance of silica gel, such as the best silicone mold resistance at the lowest temperature of -65°C.
The other is condensation mold silica gel, curing ratio of 100:2, such as 100 grams of silica gel and 2 grams of curing agent, curing agent amount is not more than 5%. Avoid impact on operation and performance. This material usually holds up to about 200 degrees.
