Polyformaldehyde: r, >Crystalline product): English name, commonly known as steel rod, steel rod Steel rods and super steel rods are made of plastic particles extruded through an extruder at high temperature, and rods of different thicknesses are obtained through corresponding die openings. It is a thermoplastic engineering plastic with high hardness and high crystallinity. Because
rod
: r, >has good properties, it is very suitable for machining on automatic lathes, and is especially suitable for manufacturing precision parts.
: r, >C/ (black, white)
<:rr, , represent copolymer and homopolymer respectively. Copolymer has low melting point, thermal stability, chemical corrosion resistance, flow characteristics, It is resistant to hydrolysis, strong alkali and thermal oxidation degradation, and its processability is better than homopolymer formaldehyde. The homopolymer has high crystallinity, creep properties, lower thermal expansion rate, wear resistance, mechanical strength, rigidity, heat distortion temperature, etc. than copolymer formaldehyde. (Currently, C copolymer is commonly used in semi-finished products on the market)

Raw material plus (Teflon) fiber
Made by extrusion. It retains most of its inherent strength. There are some performance changes due to the addition of (Teflon) fiber. It is slightly softer, less rigid, and more slippery than pure polyacetal resin. Compared with pure plate, this material has better lubricity. Bearings made of + have a medium friction coefficient, are wear-resistant, and have basically no creep.

: r, >Physical properties: Polyformaldehyde is a hard and dense material with smooth and shiny surface, light yellow or white, high crystallinity, good colorability, and constant size. , the water absorption rate is extremely small.
: r, > 2. Mechanical properties: Polyacetal has high hardness and rigidity, high resistance to creep and stress relaxation, excellent wear resistance, and self-lubrication The resistance and fatigue resistance are unmatched by other engineering plastics.
: r, > 3. Thermal properties: Polyoxymethylene has a high heat deformation temperature and can be used for a long time in the temperature range of ℃.
: r, > 4. Electrical properties: Its dielectric loss and dielectric constant change very little over a wide frequency and temperature range, and it maintains good arc resistance.
: r, > 5. Chemical properties: Polyformaldehyde has good resistance to solvents, oils, weak acids, weak alkali and other properties.
: r, > Polyoxymethylene has excellent physical, mechanical, thermal and electrical properties, resistance to organic solvents, wear resistance, creep resistance, fatigue resistance and other properties, and is widely used in replacement Various non-ferrous metals and alloys are used to make automobile, machinery, instruments, agricultural machinery and chemical parts. Such as gears, cams, bearings, bushings, gaskets, valves, liquid transportation pipelines, handles and chemical melters, etc. Especially in the automobile industry, it is widely used in making cardan shafts, carburetors, building faucets, agricultural sprayers, agricultural sprayer components, audio and video tapes, tape reels, photographic equipment and various precision instrument components.
: r, >It is widely used in manufacturing various sliding rotating machinery, precision parts, gears, bearings, etc. The industries used include automobiles, electronics, clothing, medical care, machinery, sports equipment and other fields.
