Mechanical Seal Princess——Special Engineering Plastic PEEK Gasket

Mechanical Seal Princess——Special Engineering Plastic PEEK Gasket

There are thousands of gaskets. Why is the PEEK gasket so special that it can be called a mechanical queen?

The reason why gaskets are used to seal is that the machined surface cannot be perfect and irregular, and gaskets can be used to fill the shortage to prevent pressure between two objects, corrosion, and natural thermal expansion and contraction of pipes. mechanical seal between objects.

Ordinary gaskets are usually made of sheet materials, and the material of the gasket will be changed according to the different things to be sealed, such as pad paper, rubber, silicone rubber, metal, cork, felt, neoprene, nitrile rubber, Glass fiber or plastic polymers are commonly used materials, and the excellent comprehensive performance of PEEK can well meet these needs. Peek gaskets have good sealing performance, particularly high gasket delivery rate, excellent chemical resistance, and are non-toxic. Tasteless, odorless, acid-resistant, not easy to deteriorate, compared with metal gaskets, it has excellent insulation, corrosion resistance, heat insulation, non-magnetic properties, light weight, and is widely used in all aspects.

The continuous use temperature of the gasket of PEEK material is extremely high (about 260 degrees), and it also has extremely high rigidity and hardness, as well as unique high tensile strength and fatigue strength, high creep strength, excellent dimensional stability, Excellent anti-ultraviolet performance, excellent high-energy radiation resistance, especially suitable as gasket materials, not only these, but also many special engineering plastics such as PPS, PEI, etc. are also suitable.
