The PTFE workability can be greatly improved by adding a proportion of ethylene of 25% and is formed so as ethylene tetrafluoroethylene (ETFE).
CHARACTERISTICS AND APPLICATION FIELDS
The most widespread ETFE processing is injection molding; It can be worked mechanically by chip removal.
The ETFE has a relatively high melting temperature and high electrical resistance, in addition to excellent wear resistance, corrosion resistance and tensile strength. It has an operating temperature of between -185 ° C and 150 ° C. It has good resistance to UV rays and weathering. And ‘necessary to stabilize it against chemical degradation and photochemical. The reinforcement with glass fibers increases both the stiffness is the solidity.
The ETFE is used for the production of gear wheels, components for pumps and laboratory items, in addition to being used for roof coatings, films and cable insulation.
Shown below are the most common trade names for the ETFE material.
