300℃ High-Temperature Food Grade silicone Lower Shrinkage Liquid Silicone Rubber Making Kitchenware
Description
Liquid silicone rubbers are pumpable two-part compounds that are delivered ready to use.
They are vulcanized by addition curing.
Component A contains catalyst and component B functional polysiloxane as a curing agent.
Compared to peroxide curing, liquid silicone rubbers do not release any curing by-products.

Knowledge
Q: How long does it take to cure silicone?
A: The time taken to cure a silicone compound depends on a number of factors. These include temperature, section, and cure mechanism. In practice, a typical cure time for a compression molded part is in the region of 5 minutes at 180C.
Q: What is the difference between 'curing' and 'vulcanization'?
A: Curing and vulcanization essentially describe the same thing - the transformation of the polymer into a cross-linked rubber.
Q: Why silicone rubber add curing agent after mixing a lot of bubbles?
A: This is normal physical phenomena. The liquid will produce a large number of bubbles in the mixing time, so, it must pass through the vacuum exhaust bubble treatment.
