POM rod manufacturers

Product Description: POM rod (POM crystals): English name Polyoxymethylene, commonly known as the race bar, wins bars, super steel bar POM plastic particles is extruded through an extruder temperature, after extrusion port corresponding mold different the thickness of the bar. It is a high hardness, high-crystalline engineering thermoplastics. Good features POM rod has, very suitable for automatic lathe machining, particularly suitable for the manufacture of precision parts. Model POM-C / H (black, white) represent POM POM copolymers and homopolymers, POM copolymer low melting point, thermal stability, chemical resistance, flow properties, hydrolysis resistance, alkali resistance and thermal oxidation downgrade workability than POM. POM homopolymer with high crystallinity, creep out, lower coefficient of thermal expansion, wear resistance, mechanical strength, stiffness, heat distortion temperature of geometric acetal copolymer good. (POM semi-finished products currently on the market commonly used POM-C copolymer) POM-H + PTFE (dark brown) with DuPont POM (DELRIN) materials plus PTFE (Teflon) fiber extruded from. It retains most of the inherent strength of POM-H. Because filling PTFE (Teflon) fibers have certain properties change slightly soft, small rigid, more slippery than pure polyacetal resin. Compared with pure POM plate, this material better lubricity. Bearing with POM-H + PTFE produced moderate friction coefficient, wear, and almost no creep phenomenon. The main characteristics of a physical properties: POM is a surface smooth, shiny, hard and dense material, yellow or white, high crystallinity, good color, size, weighed, water absorption is minimal. Second, the mechanical properties: POM has a high hardness and rigidity, with a high degree of resistance to creep and stress relaxation ability, excellent wear resistance, self lubrication, and fatigue, can not be compared to other engineering plastics. Third, the thermal properties: POM has a high heat distortion temperature, long-term use at -40 ℃ -104 ℃ temperature range. Fourth, the electrical properties: its dielectric constant and dielectric loss over a wide frequency and temperature range is small, it maintained a good arc resistance. Five chemical properties: POM has good solvent, oil class resistance, weak acid, weak base properties. POM has excellent physical, mechanical, thermal and electrical properties, resistance to organic solvents, abrasion resistance, creep resistance, fatigue and other properties, it is widely used in place of a variety of non-ferrous metal and alloy production automobile, machinery, instruments, agricultural machinery, chemicals components. Such as gears, cams, bearings, bushings, gaskets, valves, liquid transport pipes, handles and chemical solution or the like. Especially in the automotive industry, for the production of a large number of universal shaft, carburetor; producing faucet in the construction, agricultural spray is sprayed, part agricultural sprayer components, audio and video tapes, tape reels, photographic equipment and a variety of precision instruments, and so on.
