Q: Why could the silicone mold be reused only for a few times?

A: The tension and tear strength of the silicone mold changes. Here are some following reasons:

  1. Adding too much silicone oil into silicone rubber.
  2. Adding too much catalyst into the silicone rubber. Please add no more than 2% catalyst.
  3. Using the silicon rubber with wrong hardness to make molds for products.
