Product Description

        Tin cured molding silicone rubber,Tin-based silicone,also called condensation silicone rubber,are two-component materials which cured at room temperature(RTV) to flexible,high tear-strength rubbers.Tin cured silicone can be poured onto models or they can be made brush-able by adding a Thixotropic additive.They are ideal for molds because of easy release or high temperature resistance.

Features

•Very good flowability

•Excellent tear strength

•High elongation and flexibility

•Little rate of deformation and shrinkage

•High temperature resistance

•High tear resistance
