On ethylene tetrafluoroethylene copolymer

The ethylene tetrafluoroethylene copolymer is in English: ethylene-tetra-fluoro-ethylene, referred to as ETFE, commonly known as polyfluoroethylene, commonly known as F-40.

Specific gravity: 1.7 grams / cubic centimeter

Molding shrinkage: 3.1-7.7%

Molding temperature: 300-330 degrees centigrade

ETFE is the most toughest fluorine plastic. It keeps the good heat resistance, chemical resistance and electrical insulation of PTFE, and improves the radiation and mechanical properties to a great extent, and the tensile strength can reach 50MPa, close to 2 times of polytetrafluoroethylene.
