FEPApplication of Rod
1. what isFEPTeflon sticks?
FEP rodIs a new type of crystalline perfluorocarbon polymer, is a modified product of polytetrafluoroethylene, its long-term use temperature is-80 ∽ 200 ℃, and has excellent chemical stability, outstanding surface non-stick, low temperature mechanical strength, electrical insulation, air tightness, fold resistance, and very low water absorption and friction coefficient, in the atmosphere The exposure life can exceed 50 years.
FEP rod/F46 rod is a small amount of perfluoropropyl perfluorovinyl ether and.Teflonof the copolymer. The melt cohesiveness is enhanced, the solution viscosity is reduced, and the performance is unchanged compared with PTFE. This kind of resin can be directly processed into products by ordinary thermoplastic molding methods.FluoroplasticsF46 casing is a modified variety of PTFE, which basically retains the performance of PTFE.

2.Performance of FEP rods
1、Appearance: uniform texture, smooth surfaceBlisters, cracks, delamination, flow marks, serious dents and mechanical scratches are not allowed..
2,Long-term use temperature-80--200It has excellent chemical resistance, corrosion resistance to all chemicals, low friction coefficient in plastics, and good electrical properties. Its electrical insulation is not affected by temperature.“The Plastic King”It is called.
3,Its chemical resistance is similar to that of PTFE.vinylidene fluorideOkay.
4,Its creep resistance and compression strength are better than PTFE, high tensile strength, elongation up100-300%. Good dielectric properties, excellent radiation resistance. Flame retardant, physiologically inert, safe and environmentally friendly products.
5,Flame-retardant in air, with a ratingUL94-V0Level.
6,Corrosion resistance:Teflon is hardly attacked by chemicals.

3.FEPCommon specifications of rods
Plate (1-80mm)* 1000*2000mm; Rod (10-130mm)* 1000mm long.
4.FEPRod Teflon Rod Application Field
1Suitable for making corrosion-resistant parts, anti-wear parts, seals, insulation parts and medical equipment parts.
2High temperature wire, cable insulation, anti-corrosion equipment, sealing material, pump valve bushing, and chemical container.
3Poor fluidity, easy to decompose, decomposition of corrosive gas. Should be strictly controlled molding temperature does not exceed475degree, the mold should be heated150-200degree, the flow resistance of the pouring system should be small.
4Translucent pellets, injection molding, extrusion molding. Molding temperature350-400degree,475Above degrees, it is easy to cause discoloration or bubbles. And note that demoulding will be more difficult.
