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 wieght:
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 coefficuent. non-flammable.
5. With very low evaporate transpiration rate, cold liquid is not volatile.
6. With excellent electrical charateristics (does not change with frequency and temperature changes)
7. Excellent mechanical properties, shock resistance and flexibility.
