Foam silicone in some occasions will contact with the food, so performance reach the level of food-grade foaming silica gel.
The food grade foaming silica gel for what are the specific performance, then a look below: 1.
Low compression permanent deformation;
Production of foamed silicone should not pollute the environment;
No smell, stimulating smell;
Smooth surface evenly;
Satisfy the relevant food grade detection (
Can contact with the food)
The bore food-grade foaming silica gel can be open or closed, in addition to good foaming silicone should have: high and low temperature resistance, resistance to ultraviolet radiation, ozone resistance, electrical insulation, etc.
Afraid because be food-grade silicone, so choose material is should avoid adding chemical foaming agent;
These common foaming silica gel in the process of hot vulcanization, decomposition of foaming agent produces toxic by-products.
Choose food grade foam silicone can improve the physical properties of the finished product and reduce the production cost, when the lower bounding die pressure, has the ideal shape: low density and quality, and stronger temperature adaptability,
Under 60 ℃ ~ 250 ℃ can keep stable performance for a long time, also can be used in more than 400 ℃ short term.
