Why does the silicone rubber mold have few molding times?
       The silicone rubber 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 silicone rubber which is easy to break; making the mold for
large products with soft silicone rubber which will reduce the tensile and tear
strength of the mold, and the mold will have deformation. Thus, we should take
the proper silicone rubber to make the mold for suitable products.

RTV-2 molding Silicone rubber  instruction:

RTV-2 molding silicone rubber is mainly with the advantages of good tensile strength,
high tear strength, high temperature resistance, high duplication times and
repeated use, etc. silicone rubber(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%.

RTV-2 molding Silicone rubber features:

 
 RTV -2 silicone rubber is two parts condensation liquid silicon rubber that can
cure at normal temperature. It has excellent fluidity, tensile property and tear
strength, moderate flame-retardancy and linear shrinkage. Mainly used for the
manufacturer of products made of unsaturated resin, epoxy resin, polyurethane,
etc.

RTV-2 molding Silicone rubber application:

Silicone features: 1) For mold making, for pad printing. 2) high tensile, tear-strength.etc.3) low shrinkage 4) non-deformation
