FEP pipe and PFA pipeBetween fep tube and pfa tube,the main difference is that fep heat shrink tubing can withstand 200 ℃ and pfa hose can withstand 260 ℃.
The characters of fep hose are as follows:
(1)Fep chemical hose common colors: transparent, black.Unusual colors: yellow, brown, green, blue.
(2)Operating temperature: - 200 ℃ to 200 ℃.
(4)Anti-UV: Fep shrink tubing can be exposed to ozone and sunlight for a long time without aging.
(5)Very transparent: Because of he lowest refractive index among all plastics, the liquid flow inside fluorinated ethylene propylene tubing can be viewed clearly.
(6)Fep tube material's strong corrosion resistance: Fep centrifuge tubes can withstand all strong acids, strong oxidants, strong reducers and various organic solvents.
Volume resistance ＞ 1 × 1018；
Surface resistance ＞ 2 × 1013；
Arc resistance ＞ 165 seconds without leakage;
Low water absorption: water absorption ＜ 0.1%;
Minimum friction coefficient: minimum friction coefficient;
Surface non adhesion: the known solid material cannot adhere to the surface of fep teflon tubing.
(8)Fep lined tubing incombustibility:Tubing fep doesn't burn in the air and meet strict fire protection requirements.
(9)Coiled fep tubing is non-toxic and enviroment friendly.
(10)fep plastic tubing sizes:2 * 4mm, 3 * 5mm, 4 * 6mm, 5 * 7mm, 6 * 8mm, 8 * 10mm, 8 * 12mm, 9 * 12mm, 10 * 12mm,
12*14mm,14*16mm, 16*18mm, 18*20mm etc.
Produce heat shrink fep tubing,fep tube manufacturer want to know :Outer diameter before shrinkage, inner diameter before shrinkage, wall thickness before shrinkage, shrinkage ratio.
Teflon pfa tubing is a copolymer of a small amount of perfluoropropyl perfluoro vinyl ether and polytetrafluoroethylene.
High purity pfa tubing melt cohesiveness is enhanced, the viscosity of the solution is reduced, and the performance is unchanged compared with that of PTFE.The resin can be directly processed into products by common thermoplastic molding methods.
Pfa flexible tubing is suitable for making corrosion-resistant parts, wear-resistant parts, seals, insulating parts and instrument parts, high-temperature wires, cable insulation, anti-corrosion equipment, sealing materials, pump valve bushings, and chemical containers.
Tubing pfa main performance is as follows:
(1)Flexible pfa tubing long-term use temperature is - 196 - 260 degrees.
(2)High purity pfa has excellent chemical corrosion resistance and corrosion resistance to all chemicals.
(3)Pfa tube friction coefficient is the lowest among plastics.
(4)Pfa pipe also has good electrical performance. Its electrical insulation is not affected by temperature.
