ETFE Resin Pump Valve HY49003

ETFE(F-40) is made from 1:1 tetrafluoroethylene and ethylene copolymerization. Its molecular structure is as follows: [-cf _ 2-CF _ 2-C _ 2C _ 2N _ XN Ch _ 2-Ch _ 2N _ y] -n. Its chemical structure is similar to polyvinylidene fluoride, but different. The molecular formula of polyvinylidene fluoride is [-ch2-CH2] -n. it is soluble in dimethyl amides and dimethyl sulfoxide. Even cross-linked polyvinylidene fluoride is dissolved in these two solvents, but ETFE(F-40) is neither dissolved in these two solvents. ETFE(F-40) is formed by liquid polymerization or radiation polymerization.

Scope of application

1, suitable for making corrosion-resistant parts, wear resistant parts, seals, insulating parts and medical device parts.

2, wire, cable insulation layer, anti-corrosion equipment, sealing material, pump valve bushing, and chemical container.

3, industrial and agricultural construction film, Example: "Garden of Eden" in Britain, "Water Cube" in Beijing

4,Wire and cable are the largest market for ETFE application, accounting for 50% ~ 60% of ETFE application market. ETFE, which is mainly used as control line signal line and communication line, is suitable for high environmental requirements, such as ETFE for transporting aero-chemical and nuclear plant wells and various cables and communication lines downhole. Intrinsic lubricity helps cable pass through complex and curved channels, while its insulation integrity is guaranteed because of its wear resistance. The properties of hot-welded iron, such as non-burn-through and mechanical puncture resistance, are also required for cable.
