Food Grade Liquid Silicone For Food Safe Silicone Rubber Candy Mould Making With FDA, REACH
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.

Instructions
Here is a look at the LSR molding process:
1. LSR A + B components typically come in a 5-gallon pail or 55-gallon drum. A process controlled pumping kit presses down on the buckets to force the material into the static mixer and feed into the injection unit.
2. Then, streams of pigment can be added and controlled. In the injection, press material will be mixed together additionally with a screw and pushed forward to create a “shot” of material, or the amount needed to fill the mold.
3. After the material is injected into the mold, it will then stay clamped together to cure the LSR. Then, either an operator or a robot will remove the cured product from the mold and the cycle repeats. It is a very quick efficient process that typically averages 30 seconds.
