[Section] a seal or oil seal made of perf ether
2019-06-06

The fluorine ether rubber seal (oil seal) is composed of TFE (main chain), PMVE (branch chain) and Bridge Part. it not only has excellent high temperature resistant seals like PTFE, the performance of chemical corrosion resistance (can withstand the corrosion of more than 1600 chemicals), and also has the elasticity of rubber, and its compression deformation rate at 300 °c is only below 50%.

Ordinary all-fluorine rubber seals (Oil Seal)The operating temperature range is-25 ℃ ~ Between 240 °c, The perf rubber 7075 has a high temperature resistance of up to 327 °c, even when exposed to a constant temperature of 316 °c or an intermittent high temperature environment like 343 °c, fluorine ether rubber production will not lead to hardening and brittle sealing failure, and fluorine ether rubber can still maintain its elasticity and rebound performance in direct contact with aggressive fluids.In fact, the thermal stability of fluorine ether rubber often exceeds those of the fluid itself.

All-fluorine rubber seals (Oil Seal)It also has excellent air tightness (The degree of vacuum resistance can reach 1.33X10-7-1.33X10-8 PA)With high cleanliness and ion resistance, these features are also widely used in the semiconductor industry.

Wow, this sounds like a bit of a cruel question, but it is a vitally important question to ask yourself if you are struggling with your custom rubber seals and you would like to stop the rubber seal problem.
should only be created by the very best rubber seal companies with the training, experience and know how about what is expected of them.
It's the consistent experience that builds trust and loyalty. Creating a personality and platform that is scalable will allow you to evolve rubber seal with your consumers.
