Character of PTFE
The PTFE hose material is made of Japanese Daikin.
The temperature range is -200C to +260C, melting point: 327C. It
can't be injection molded and can be pressed and formed. The max.
operating temperature is 280C.
PTFE has the following excellent properties due to its strong
carbon-fluorine bond and high molecular weight:
1. Excellent weather resistance, long service life, no brittle
fracture, and no aging.
2. Resistant to strong acid and alkali, resistant to various
corrosive chemicals.
3. Anti-adhesive, anti-moisture and ultraviolet, non-toxic.
4. With a very low friction coefficient. non-flammable.
5. With a very low evaporate transpiration rate, the cold liquid is
not volatile.
6. With excellent electrical characteristics (does not change with
frequency and temperature changes)
7. Excellent mechanical properties, shock resistance, and
flexibility.
