40 Shore A Food Grade Liquid Silicone Rubber For Foldable / Collapsible Kitchenware
Food Grade Two Component Liquid Silicone Rubber For Foldable / Collapsible 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.
