rtv Silicon for complex products' mold making

1. General description of Silicon for  complex products' mold making

rtv Silicon (HY-638 ) is two parts condensation liquid silicone rubber that can cure at normal temperature. It has excellent fluidity, tensile property and tear strength, moderate flame-retardancy and linear shrinkage.

2. rtv Silicon for complex products' mold making(HY-638) features:

HY-638# rtv silicon is mainly with the advantages of good tensile strength, high tear strength, high temperature resistance, high duplication times and repeated use, etc.

3. Tips of rtv Silicon for complex products' mold making

rtv silicon(HY-638) is the most 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 less than 0.2%.

4. Frequently asked questions of rtv Silicon for complex products' mold making

Why does the rtv silicon mold have few molding times?

The rtv silicon mold has few molding times is due to follwoing reasons: Adding too much silicone oil which will destroy the molecular of silicone rubber;

Making the mold for small and fine detailed products with higher hardness rtv silicone rubber which is easy to break;

Making the mold for large products with soft rtv silicone rubber which will reduce the tensile and tear strength of the mold, and the mold will have deformation.

Thus, we should choose the proper rtv silicone rubberfor suitable products to make mold.
