Audited Supplier The main field of application of PCTFE(Kel-f) is cryogenics due to the fact that it is the fluoropolymer that best retains its mechanical properties at extremely low temperatures and is therefore the least fragile of the fluoropolymers. PCTFE is incompatible with alkaline metals and in some cases with organic amines.
PCTFE soft seat insert or seal is the important components in the cryogenic valve industry.
Main Porperties:
• Excellent low temperature resisitant
• Good mechanical property
• Low coefficient of linear expansion
• Good dimensional stability
• Good penetration function
• by keeping a large stock of the semi-finished materials used by our regular customers, we can meet urgent requests and have quick turnaround
• In-house manufacturing of semi-finished rods/tubes for CNC,with multiple tools ensure the best optimization of nominal diameters so as to offer dimensions as close as possible to the finished products to be made,reducing swarf,machining times and related costs.
• In-house CNC machining of all kinds of soft seal materials including seats&inserts,O-rings,back-up rings,piston seals,gasket,bearing... according to customers' drawing.Facilities including Milling & Turning, CNC lathes,Carving,Multi axis CNC, Welding and mold injection...
• a wide range of sizes up to a diameter of 650mm,make us the partner of choice for industrial machined parts of high-end OEMs.
• with multiple tools ensure the best optimization of nominal diameters so as to offer dimensions as close as possible to the finished products to be made,reducing swarf,machining times and related costs.
