The gasket is widely used in the laboratory and chemicals seal and packing, sold  far to developed countries such as Europe and the United States. The characteristics are as follows:
1, Using  PTFE and high-quality silicone rubber as  material determines that the gasket is non-toxic.
2, The  special production technology combines the excellent character of PTFE and silicone rubber to produce a new type of sealed packaging.
3, The compound gasket has a good chemically inert of acid-proof, alkali-proof, temperature-proof and anti-stick, so that it does not act when combined with concentrated acid, alkali or strong oxidizer even under high temperature.
4, The compound gasket has good physical performance of elasticity, tightness and  lubricity.
5, Special processing technology makes sure the PTFE and silicone rubber stick  firmly and the two materials are not easily separated.
6, Strict production management ensures the absolute quality of the product. Through cleansing the products can be used directly without cleaning.
