Applications

TPD-901: Mainly used to produce lingings of pipes, pumps, valves, tank and bearings, etc.
TPD-902: Mainly used to produce pipes, wire insulation layer, membranes and various parts.
TPD-903: Mainly used for extrusion process, used to produce the layers of wire and cable;
TPD-904, TPD-905 and TPD-906: Mainly used to produce high-speed extruded wire and cable.

Cautions

The processing temperature should not exceed 425℃, to prevent PFA decompistion which will promote equipment corrosion.

Packing

Woven plastic bag with inner polyethylene bag, net weight 25KG.

Transportation & Storage

Transported as non-dangerous cargo.

Stored in clean, cool, dry, dark and ventilated places, avoid contamination.

Polyvinylidene fluoride(PVDF)

Polyvinylidene fluoride (PVDF) micropowder a kind of fluoropolymer products with many excellent properties, such as strong toughness, low friction coefficient, strong anti-corrosion resistance, aging resistance, weather resistance, high dielectric strength and good radiation resistance. It is widely used in fluorocarbon coatings, valve lining, anti-corrosion coatings, also can be used to make capacitor film, lithium battery separator film and various piezoelectric products of electroacoustic components.

Fluorinated ethylene propylene(FEP)

Fluorinated ethylene propylene(FEP) resin is a copolymer of TFE and HFP. FEP resin has excellent properties similar to polytetrafluoroethylene (PTFE) and has the characteristics of thermoforming.

FEP has a melting point temperature of 260 ± 5 ℃, relative density of 2.12-2.17, features of chemical inertness, acid and alkali resistance, excellent weather resistance (use temperature range – 80-200 ℃), low dielectric constant in a wide range of temperature and frequency, incombustibility and low friction coefficient.

FEP resin can be molded and extruded into inner lining of pipe and chemical equipment, surface layer of roller and various wires and cables, such as aircraft hook wire, booster cable, alarm cable, flat cable and well logging cable.
