FAQ
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:
- Adding too much silicone oil into silicone rubber.
- Adding too much catalyst into the silicone rubber. Please add no more than 2% catalyst.
- Using the silicon rubber with wrong hardness to make molds for products.
Packaging & Storage
- RH6250-50YH Medical is available in 20kgs pails or 200kgs drums.
- Store in a cool dry place out of direct sunlight, use it within 12 months from the day of manufacture.
