DuPont POM wear-level distributor of imported plastic 500CL

The definition of DuPont POM POM wear-level distributor of imported plastic 500CL application: You can replace most non-ferrous metals, automobiles, machine tools, instrumentation internal parts, bearings, fasteners, gears, springs, pipes, conveyor belts accessories, electrical kettles, pump casing, drain device, faucets and other DuPont POM process features: front (1) POM can be processed without drying, preferably preheated (about 800 ℃) in the process, the stability of product sizes have benefits. (2) POM very narrow processing temperature (0 ~ 215 ℃), slightly longer residence time in the barrel or when the temperature exceeds 220 ℃ will break down, resulting in strong irritant formaldehyde gas. (3) POM material injection When the holding pressure to be larger (similar to injection pressure) to reduce the pressure drop screw speed is not too high, the residual amount is less;. (4) POM product shrinkage is large, easy to produce shrinkage or deformation .POM large specific heat , high mold temperature (800 ~ 100 ℃), product ejection when very hot, the need to prevent scald your finger. (5) POM should "press the speed, low melt temperature, mold temperature higher" Under the conditions of molding When required precision molding products mold temperature control (6) with high mechanical strength and rigidity (7) the highest fatigue strength (8) environmental resistance, resistance to organic solvents (9) resistance to repeated impact resistance, good electrical nature, good recovery, with self-lubricating, wear good, excellent dimensional stability of a synthetic resin, also known as Delrin, POM plastic, steel and other materials race;. is a white or black plastic particles with high hardness, high rigidity, high wear-resistant properties. Mainly used for gears, bearings, auto parts, machine tools, instrumentation and other pieces from the skeleton in the role of products. DuPont POM POM plastic particles performance of: (1) POM is a crystalline plastic, a density of 1.42g / cm3, it is very good steel, commonly known as the "Race of steel" (2) It has resistance to fatigue, creep. excellent performance wear resistance, heat resistance, impact resistance, etc., and low coefficient of friction, self-lubricating. (3) POM easy to moisture absorption, water absorption was 0.22% to 0.25%, in a wet environment, good dimensional stability, shrinkage 2.1% (larger), when the injection size is difficult to control, heat distortion temperature of 172 ℃, pom pom and there are two acetal copolymer [1], different properties (POM temperature resistance point) .
