Silicone Raw Material for Mold Making

Advantages of silicone raw material for mold making

A. Shore A from 15 to 40 hardness

B. Good fluidity and good operability and good for pouring method.

C. Excellent mechanical properties, in particular tear strength and tensile strength.

D. Excellent flexibility and it is easy to demould.

E. High temperature resistance, high duplication times and repeated use.

F. There are a range of catalysts/curing agent/hardener allows the Liquid rtv silicone rubber  to fulfill requirements for various applications and various requirements on the operation time and curing time.

Why RTV-2 Molding Silicone Rubber?
Economic Use
As the most stable polymer available, silicones offer superior reliability, excellent service life and reduced production costs.
Versatile Application
Silicone rubbers cure in deep sections as needed for electrical potting and encapsulating, casting rubber parts, arts restoration, general handy crafts, lost wax casting process, plaster forms, seals, stage decorations, statuettes and many more.
Chemical Resistance
Silicones resist acids, bases, solvents, chemicals, oils and water.
