Characteristics of PTFE Envelop Seal

PTFE envelope gaskets for tank container applications combine the chemical inertia and hygienic qualities of 100% virgin PTFE with the mechanical properties of the compressed non asbestos fiber sheet, with good corrosion resistance and high temperature resistance, used in chemical, pharmaceutical, food and other industries be widely used. The special structure of the gasket can effectively prevent leakage problems without affecting the purity and quality of the liquid inside the container.

SUNPASS PTFE Envelop Seal contains a lot of rubber and great toughness, so it is relatively difficult to break. There is a lot of rubber, it ages easily, and it is more likely to break due to high outdoor temperatures.

Our softness and hardness are in the middle, with a good balance between flexibility and aging resistance, and the content of rubber is moderate.
