Extruded Silicone Rubber 6250-15 100% Food Safe Silicone Making Baking Molds And Trays
Extruded Silicone Rubber 6250-15 100% Food Safe Silicone Making Baking Molds And Trays
Description
LSR 6250-15 A/B is food grade liquid silicone rubber for injection molding processes.
At higher temperatures the safety operation time shortened.
LSR RH6250-15 liquid silicone rubber is platinum cured(vulcanized) materials which are mixed in a 1:1 ratio by weight.
Food grade silicone rubber offers the strength and stress resistance required to manufacture baking trays, bottle dispensers, food grade gasket sealant, and other products for the kitchen and throughout the home.
Key Features and Benefits
Liquid silicone rubber molding has several advantages, including:
- Food grade silicone rubber
- Non-stick nature
- Neutral odor and taste
- Good transparency
- High thermal stability
- Easy pigmentable

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.
