Product Description

 

 

 RTV2 molding silicone rubber is mainly used for poured or brush onto products for casting polyurethane,epoxy, polyester resin, gypsum/plaster, cement, waxes, low melt alloys/metals, etc.  with the advantages of low viscosity, good tensile strength, high tear strength, high temperature resistance, high duplication times and repeated use, etc. It is suitable for small products or fine and precision products which is difficult to demould.

This silicone rubber is one of the products with the highest use level in the production of craftwork gifts and the shrinkage is up to 3.

RTV silicone rubber used for Poly technique, lightings, candles, soap and molds with small and medium size.

 

Features
• Low Shore A hardness (approx. 25A)
• Excellent tear strength
• Very high elongation and flexibility
• Little rate of deformation and shrinkage
• High temperature resist,high tear resist
