Applications of RTV silicon rubber for making moulds polymer clay molds :
For the duplication and mold making of big size products of poly resin crafts, PU crafts, gypsum or plaster, unsaturated resin, lighting and candles crafts, plastic toy, stationery gifts crafts,large statue Buddha, furniture decoration, cemen, artificial stone, etc.
Description of RTV silicon rubber for making moulds polymer clay molds :
HY-625silicone rubber is mainly used for the duplication and mold making of big size products of poly resin crafts, PU crafts, gypsum or plaster, unsaturated resin, lighting and candles crafts, plastic toy, stationery gifts crafts,large statue Buddha, furniture decoration, cemen, artificial stone, etc. It is with the advantages of 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 2‰.

The proportions and reactions of the curing agent and the silicon are listed as follows:
1. Adding curing agent 1%, the silicone can still be operated within 2.5 hours and can be demoulded after 6-8 hours.
2. Adding curing agent 2%, the silicone can still be operated within 50 minutes to 1 hour and can be demoulded after 2-3 hours.
3. Adding curing agent 3%, the silicone can still be operated within 28 - 30 minutes and can be demoulded after 1.5-2 hours.
4. Adding curing agent 4%, the silicone can still be operated within 10 - 15 minutes and can be demoulded after 1 -1.5 hours.
Why could the silicone mold be reused only for a few times?
It can be due to the following reasons:
a. Adding too much silicone oil in to silicon rubber. Silicon oil is an additive which destroies the molecular weight
of silicone rubber and reduce the tension and tear strength.
b. Using the silicon rubber with a high hardness to make molds for small sized products with delicate and intricate
designs and the silicon rubber with a low hardness to makes molds for large sized products with simple designs.
(Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.)
