Semi finished products of polytetrafluorethylene (PTFE)

Our products

Product category: Semi finished products of polytetrafluorethylene (PTFE)



Characteristic of the products

PTFE pipe is made by plunger extrusion of suspension polymerized PTFE resin. Among all
the existing plastics, PTFE has the best corrosion-resistance and dielectricity.

Use of the products
Lead insulating sleeve, corrosion-resistant pipe, and corrosion-resistant insulating pipe for
different corrosive conditions, heat exchanger.

PTFE Filling Product

Polytetrafluoroethylene(PTFE)  Filling Product
PTFE has good overall performance such as heat or cold resistance, corrosion-resistance, non-adhesiveness,
self-lubrication, good dielectricity, and low friction coefficient. However, compared with other plastics, its mechanical
performance is not good in low abrasion and creep resistance, low hardness. Mechanical performance can be
greatly improved   and other good property of PTFE is maintained by adding to PTFE filler which can stand PTFE sinter
temperature (360℃-380℃). Fillers can be glass fiber, metal, metal oxide, graphite, MoS2, carbon fiber, polyamide.

Characteristic of the products
Enhanced PTFE product has strong corrosion-resistance and friction-resistance. By adding filler such as glass fiber,
carbon fiber, copper powder, graphite, asbestos, MOS2, AL2O3, carbon powder, ceramic   fiber, metal powder,
polyamide, PS, hardness, compression strength and abrasion-resistance of the product is improved. In addition,
it will have good heat conductivity and low heat expansion coefficient.

Use of the products
As enhanced product has good corrosion-resistance, low friction and good hardness, it is widely used for the production
of washer, valve, bearing, slide, piston ring, insulating   sleeve, and self-lubricating seal.

Product specification
We can supply enhanced PTFE product such as cylinder, washer, sealing ring. Special product such as irregular
shaped parts can be made to order.

PTFE Shaped Parts

Polytetrafluoroethylene(PTFE)  Shaped Parts

Characteristic of the products
PTFE   irregular shaped part and liner is made by post process or special treatment of PTFE material,
which is difficult to be done by mould press method.

Use of the products
It is suitable  for seal under -180℃-+250℃  and different corrosive conditions , parts of corrosion-resistant 
pipe, corrosion-resistant chemical vessel , friction-reduction of machinery , self-lubricating material ,
insulating   parts for different  frequency.

PTFE Steel-Plastic component Pipe

PTFE steel plastic compound pipe is extruded by high quality plunger. Special processing method is used to get a close joint between steel pipe and plastic pipe. It can  bear positive pressure of 1.6Mp and negative pressure of  77Kpa and be used under-60℃~+260℃. It has excellent corrosion-resistance. No other pipes can replace it for the transfer of highly corrosive gas or liquid under high temperature.
