Product introduction
PTFE composites material
 |
 |
 |
As the most widely used fluoropolymer, PTFE is the most chemically corroded plastic, with the best dielectric properties and a wide operating temperature range.
LIANYI modified PTFE matrix composite material uses polytetrafluoroethylene as the matrix, filler-filled or fiber (or fabric) reinforced composite material. Specially used in aerospace, shipbuilding, electrical and electronic insulation, chemical, engineering machinery, automotive industry and other fields.
Product range
Gaskets, sealing components, insulating parts, filled PTFE piston rings, guide rings, machine tool guides, bridge sliders, Valve seat valve plate and pipe lining, can also make PTFE rod, plate, tube, packing, gasket and other types
