Analysis of the classification and application of PTFE tubes: their main use is as a dry powder lubricant, this type of resin with the continuous improvement and improvement of performance, is gradually expanding its scope of application. Kill.

Dispersion PTFE is mainly used in the manufacture of corrosion resistance, high temperature resistance, high dielectric wire and cable. In the chemical industry, mainly used in the manufacture of threaded sealing raw material belt, pipe lining and so on. Kan

(1) high compression ratio powder: extruded under the condition that the compression ratio is greater than 2500:1, suitable for processing into thin-walled tubes and wire insulation sheaths with a diameter of 2mm or less and a wall thickness of 0.2~0.5mm. Great, great.

(2) medium compression ratio powder: it is extruded under the condition that the compression ratio is greater than 400:1, and is suitable for processing into medium-sized thin-walled pipes with a diameter of 2~15mm and a wall thickness of more than 0.5mm. Great, great.

(3) Low compression ratio powder: It is extruded under the condition that the compression ratio is less than 300:1, and is suitable for processing into thicker pipes and thicker bars with a diameter of more than 5mm for making sealed raw material belts.

The application of PTFE concentrated dispersion is mainly used as an anti-sticking coating in food, textile, printing and dyeing, papermaking industries, as well as impregnated glass cloth, asbestos, etc., and can also be used for glass fibers and porous materials. Kill.

PTFE products classification overview:

(1) PTFE pipe: can produce micro thin-walled capillary tube, push tube, plunger extrusion tube, etc. At present, the maximum diameter of the domestic plunger extrusion tube is 320mm, and the length is 4~6m. Kan

(2) PTFE plate: the maximum area of the molded plate can reach 1.2 × 1.2 m2. Turning plate: turning with equal pressure forming blank, the plate width can reach 2m, and the plate width is 1.5m by pressing forming blank. Kan

(3) PTFE bar: can produce all kinds of general bar. Molded bar up to 1.5m, equal pressure molding up to 2m, plunger extrusion method up to 4~6m. Kan

(4) PTFE film: PTFE film has oriented film, non-oriented film, semi-oriented film. At present, the widest domestic film can reach 600mm. Kan

(5) PTFE impregnated glass cloth: PTFE impregnated glass cloth can only produce products with a width of 1.5m due to the substrate (glass cloth) and equipment restrictions, and can also produce PTFE impregnated glass cloth that can be bonded. Kan

(6) expanded PTFE rib sealing tape: PTFE rib sealing tape has a thickness of 0.075~0.1mm and a width of 13, 22, 26, 52mm and other specifications. many domestic units can produce and export in large quantities. Great, great, great.

(7) Biaxially stretched PTFE microporous membrane and its composite materials: PTFE microporous membrane can be used as a filter material for the filtration of ultra-pure reagents, with a pore size of 0.1 ~ 1μm; It can also be compounded with fabrics to make advanced waterproof and moisture permeable clothing fabrics and high temperature resistant filter materials. The width of composite material is up to 2m. Kan

(8) expanded PTFE sealing tape, packing, filler rod: used as chemical anti-corrosion and other aspects of the sealing material, the use temperature is -218~320 ℃; Among them, the thickness of the sealing tape is 0.5~5mm, the widest is 80mm. Packing rod diameter 1~25mm. Kill.

(9) PTFE fiber: foreign PTFE fiber made of fabric as a filter material, domestic PTFE fiber and fabric samples. Kan

(10) PTFE filled modified products: In order to improve the creep characteristics and wear resistance of PTFE, PTFE filled modified, the main materials are graphite, carbon black, molybdenum disulfide, glass fiber, carbon fiber, polyphenylene sulfide and so on. Kan

(11) PTFE corrugated pipe and reinforced pipe: corrugated pipe and fiber or steel wire braided reinforced hose made of secondary processing have the characteristics of high and low temperature resistance, pressure resistance, corrosion resistance, non-stick and long service life. Suitable for hose connections for hydraulic, pneumatic, steam delivery, etc. Kan
