Pure PTFE gasket has a regular molecular chain structure and high crystallinity. Although it has strong solvent resistance, it still has a slight swelling in certain organic solvents.
In modern chemical, pharmaceutical, petrochemical, and electroplating industries, pipeline systems often carry strong acids, strong bases, organic solvents, or high-temperature corrosive media. These fluids place extremely stringent demands on valve mater
PTFE gaskets are known as the "special forces of the sealing world" precisely because of their exceptional environmental adaptability, unparalleled corrosion resistance.
The elastic modulus of stainless steel hose and accessories is lower than that of carbon steel, and they are prone to local deformation under vibration or thermal expansion and contraction.
From the perspective of energy conversion, a low friction coefficient means less mechanical energy is converted into heat energy.
PTFE gasket stands out for its exceptional chemical stability, earning it the nickname "the king of plastics" and the "poison-proof" seal.
