Food grade silicone o-ring

Food grade silicone o-ring manufacturer

Food-grade silicone O-ring refers to those that can pass FDA food-grade detection certification. Generally, this kind of O-ring is produced with gas-phase silica gel. The difference between food grade silicone O-ring and general silicone ring is:
1.look at the difference in surface change: the general silicone ring elongated when white, and can not pull very long, and food grade silicone O-ring is different, how to pull will not white, and can pull relatively long will not break, good products can be pulled to more than 700%.
2. physical energy such as: tear strength, tear strength, elongation rate are better than the general silica gel ring.
3.transparency: higher than the general silicone ring transparency.
4.production and raw material cost: than the general silicone ring production cost is higher, and environmental performance is better.
