Product Description: POM plate, bar (POM board): English name Polyoxymethylene, commonly known as the race plate. POM plastic particles with high-temperature extrusion through an extruder, after extrusion port corresponding mold plates of different thicknesses. Is a high melting point, high-crystalline engineering thermoplastics. Good features POM plate has, very suitable for automatic lathe machining, particularly suitable for the manufacture of precision parts. POM plate, bar is a no no side chain, high-density, high-crystalline copolymer of polymer with excellent overall performance. POM plate, bar is a surface smooth, shiny, hard and dense material, black or white, long-term use in the -40- 106 ° C temperature range. Its wear resistance and self-lubricating plastic is superior than most, and good oil, peroxide-resistant performance. Very acid, alkali and impatience impatience moonlight ultraviolet radiation. POM is a crystalline plastic, melting point significantly, once they reach the melting point, melt viscosity decreased rapidly. When the temperature exceeds a certain limit or the melt heated for too long, it will cause decomposition. POM has good overall performance in thermoplastics is the hardest, it is one of the mechanical properties of the plastic material closest varieties of metal, its tensile strength, flexural strength, fatigue resistance, abrasion resistance and electrical properties are very good, long-term use between -40 degrees - 100 degrees. POM plates, rods generally have the following model POM-C / H (black, white): representing POM POM homopolymer and copolymer, POM copolymer low melting point, thermal stability, chemical resistance, flow characteristics, hydrolysis resistance, and thermal oxidation of alkali downgrade process better 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): POM-H + TF is 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 manufacturing low coefficient of friction, wear, and almost no creep phenomenon. POM plate rod main characteristics of high mechanical strength, stiffness, high hardness, excellent elasticity, slip resistance and abrasion resistance, good creep resistance, even at low temperatures, high impact strength, very good dimensional stability, excellent mechanical properties, physical inertia, suitable for contact with food. You can not use common epoxy adhesive glue AB. POM plate, bar applications: POM is widely used in the manufacture of sliding rotating machinery, precision parts, gears, bearings. Use industry throughout the automotive, electronics, clothing, medical, machinery, sports equipment and other fields. POM board Size: 0.5mm-120mm * 510 / 610mm * 1000 / 2000mm POM rods Size: Φ3-360mm * Color 1000 / 1200mm POM plate bar are: white, black, blue, green, gray, red yellow, other colors can be customized performance POM performance values ??specific gravity 1.43 Melting point 175 ° C tensile strength (yield) 70MPa elongation (yield) 15% (fracture) 15% impact strength (unnotched) 108KJ / m2 (with a notch) 7.6KJ / m2 Tip: Due to internal POM plate stress, to prevent stress and deformation, before processing and subject to the elimination of internal stress, and preventing plate bending.
