PTFE AND PRODUCTS

Detailed Product Description
PTFE SEMI-PRODUCTS PTFE(polytetrafluoroethylene)is the best chemical resistance plastic. It has the lowest coefficient of friction of all known solid materials and a wide range of working temperature from-180 to +260℃. APPLICATION: Resistance to chemical corrosion:Pipe hose,thin-wall beaker, reactor valve,diaphragm pump,lining of pipe-line equipment,filter etc. Resistance to aging, low friction coefficient: gland packing, pump seal, pull-rod sealing ring, mechanical seal, bearing, piston ring, guide ring, valve seat,valve clack,buffering ring etc. Good dielectric property: Wire and cable,insulating bushing of instrument,capacitor,radio insulation,transformer insulation etc. Self-cleaning property: Exterior wall coating,bridge slide block, machine guide track etc. Waterproof: Filter film,raincoat,sport suit,tabernacle etc. PTFE PLATE Length(mm) X Width(mm) Thickness(mm) Nominal tolerance 150 X 150; 250 X 250; 300 X 300 1～65 ±0.30～±0.50 450 X 450; 600 X 600 2～65 ±0.30～±0.50 800 X 800；1000 X 1000; 1200 X 1200；1500 X 1500 2～65 ±0.30～±0.50 1000 X 2000 5～35 ±0.30～±0.60 Φ100～400 1～2 ±0.30～±0.50 Φ400～1000 2～65 ±0.30～±0.50 PTEF TUBE & PIPE Specification outside diameter (mm) wall thickness (mm) Length (mm) Nominal Tolerance Nominal Tolerance 24 X 2～29.6 X 2 24～29.6 ±.65 2 ±0.30 1000～4000 32 X 2～50 X 5 32～50 ±0.80 3.5～5 ±0.30～±0.38 51 X 2～82 X 3 51～82 ±0.95 2～3 ±0.30～±0.38 90 X 3～104 X 3 90～104 ±1.10 3～3 ±0.30 129 X 3.5～204 X 4 129～204 ±1.20 3.5～4 ±0.35 PTFE BAR TYPES Diameter(mm) Length(mm) Nominal tolerance Nominal tolerance SFFBN 4,5,6 +0.48 0 100 +5.0 7,8,9 +0.58 0 SF X BN 10,13,15,16,18 +1.10 0 1000 +3.60 20,25,30 +1.30 0 35,40,45,50 +1.60 0 55,60,65,70,75,80,85,90,100 +2.00 0 100-300 +2.50 110,120,130,140,150 +2.50 0 180,200,250,270,300 +3.0 0 150 +2.0 Typical properties Item unit value Density g/cm3 2.10-2.30 Tensile strength(min) MPa 18 Ultimate elongation(min) % 230 FILLED PTFE PRODUCTS size unit value outside diameter mm 12-310 inside diameter mm 4.3-286 height mm 2-5 Note: Filler: glass fiber; carbon fiber; MoS2; graphite; PI; PPS; SiO2 ; bronze powder; polyphenyl, etc Typical properties Item unit value Density g/cm3 2.10-2.30 Tensile strength (min) MPa 15.0 Ultimate elongation (min) % 150 PTFE FILM 1.
