If you meet these kind problems during making silicone rubber mold, we are eager to provide you the technical solutions,here I provide you the contact information as follows:

2. Why is the tear strength of the silicone mold weak?
In order to reduce the viscosity of silicone rubber and pursue a good quality, you may add a lot of silicone oil into the silicon rubber when making molds. In fact, it might have just the opposite effect. The tension and the tear strength will be reduced badly with the addition of silicon oil. And the silicon molds will be in a weak and flimsy manner.

(Notes: we should choose the silicon rubber specifically according to the requirements of our products to avoid this problem.)

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.

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.

It can be due to the following reasons:

1. Why could the silicone mold be reused only for a few times?

Silicon features:1) silicone with high tensile & tear strength 2)Low linear shrinkage 3) Reasonable price 4)Curing agent for fre
