Pom Plastic material, a kind of synthetic resin, also known as POM Resin, POM plastic, steel, etc. . It is a kind of white or black plastic particles, with high hardness, high steel, high wear resistance. Mainly used in gears, bearings, automotive parts, machine tools, instrument parts and other skeleton role of the product. Chinese name POM plastic raw material, also known as Polyformaldehyde resin-shaped, white or black plastic particles, point high hardness, High Steel Content 1 define 2POM PERFORMANCE 3POM application 4 process characteristic define edit POM plastic granule POM performance edit (1) is crystalline plastic, density is 1.42 G / CM3, its steel is very good, commonly known as "Sai Gang" . (2) it has excellent properties such as fatigue resistance, creep resistance, wear resistance, heat resistance, impact resistance, etc. . (3) POM is not easy to absorb moisture, the water absorption rate is 0.22 ~ 0.25% , the dimensional stability is good in the humid environment, the shrinkage rate is 2.1% , the dimension is difficult to control in injection molding, the temperature of thermal deformation is 172 °C, POM has two kinds: HOMOPOLYFORMALDEHYDE and Copolyformaldehyde, different Properties homopolyformaldehyde temperature resistance is better. POM application editing can replace most of the Non-ferrous metal, cars, machine tools, instrument internals, bearings, fasteners, gears, spring plates, pipes, conveyor belt accessories, electric water cookers, pump shells, drains, taps and so on. Process Feature Edit (1) POM can be preheated at about 80 °c before POM is processed, which is good for the dimensional stability of POM. (2) the processing temperature of POM is very narrow 0 ~ 215 °C, and it will decompose when it stays in the barrel for a little longer time or when the temperature exceeds 220 °C. (3) the pressure of POM injection should be close to that of injection to reduce the pressure drop. Screw speed can not be too high, residual less; (4) POM product shrinkage rate is large, easy to produce shrinkage or deformation. Pom Specific Heat, mold temperature 80 ~ 100 °C, product demoulding very hot, need to prevent scald fingers. (5) POM should be processed under the conditions of "medium pressure, medium speed, low material temperature and high mould temperature" , precision products shall be molded using a control die temperature (6) with high mechanical strength and rigidity (7) highest fatigue strength (8) environmental resistance, good resistance to organic solvents (9) good resistance to repeated impact, good electrical properties, good recovery, with self-lubrication, good wear resistance, dimensional stability.
