1.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 silicone rubber when making molds.
In fect, it might have just the opposite effect. The tension and tear strength will be reduced badly with the addition of silicone oil. And the silicone molds will be ina weak and flimsy manner.
2. Why could silicone mold be reused only for a few times?
It can be due to the following reasons:
A: Adding too much silicone oil to silicone rubber. Silicone oil is an additive which destroy the mole cular weight of silicone rubber and reduce the tension and tear strength.
B: Using the silicone rubber with a high hardness to make molds for small sized products with delicate and intricate designs, and the silicone rubber with a low hardness to make molds for large sized products with simple designs.
Notes: we should choose the silicone rubber specifically according to the requirement of our products to avoid this problem.
