Antifouling finishing properties of (PTFE)teflon coatings
（1）The
clothes
Keeping their clothes clean is no longer
a problem for many children returning to school after the holidays. Their
tracksuits, skirts and trousers are treated with teflon-coated anti-fouling,
which keeps the children's clothes looking sleek and tidy. The clothes also
stand the toughest tests of comfort, even when they are close to sensitive
parts of the body. For office workers, leaving coffee stains or ink stains on
their clothes can be embarrassing. Make consumers' life more comfortable.
（2）Leather
aspect
(PTFE)Teflon coated antifouling finish gives
leather perfect waterproof and antifouling protection. But when it comes to
vision, taste and touch, consumers are unaware of the TeflonB coating.
（3）other
aspects
Teflon coating finishing is not only
used in the field of clothing and leather, but also widely used in luggage,
umbrella and other textile products, hunting and fishing and other recreational
textiles, bedding, all kinds of decorative textiles and so on.
Surface
properties：
The molecules slide easily between each
other, and the friction coefficient is the lowest in all polymers. It has good
lubricity, is difficult to be wetted by ordinary liquid, and has little
adhesion to other substances.
Chemical
resistance：
Teflon is even more resistant to chemical corrosion than
rare metals. Except perfluoroalkane and perchloroalkane can make it slightly
swelling, ketones, ethers and other organic solvents can not act on it. Because (PTFE)teflon has little wettability, its absorption rate to acid and alkali solvent
is very low. Even at high temperature, concentrated acid, concentrated alkali
and strong oxidant cannot react with teflon uplift.
Heat and
climate resistance:
Teflon has good thermal stability, and is not affected by
oxygen, ozone and ultraviolet radiation, and is not easy to age. The combustion
oxygen index of teflon is greater than 95, which is incombustible.
