Platinum Cure Silicone Molds Rubber 40 Shore A Transparent Liquid Silicone Rubber
Description:
MC Silicone MCPLA-H40 is a two-component elastomeric material consisting of Silicone Base, which when mixed with Curing Agent,cures to an elastic and resistant material at room temperature by an addition reaction. The curing can be heat accelerated. A range of materials can be cast into the cured silicone mold.
Features:
Good flowability
High ter and tensile strength
Flexible and dimensional stability
Easy to de-air
Long shelf life with low shrinkage
Applications:
Label manufacturing, hearing aid earmold, molding applications requiring low shrinkage e.g., jewelry, automotive. It can be used to make exceptionally strong and tear resistant molds for casting wax, resins and other materials, etc.
