Polyoxymethylene (POM) plastic Basics
POM is a highly crystalline polymer, with surface smooth, shiny, water absorption of small size stability, wear resistance, high strength, self-lubricating
Well, color is good, oil-resistant peroxides. POM has good overall performance, in the thermoplastic plastic is hard, plastic
Mechanical properties of materials, one of the closest varieties of metal, its tensile strength, flexural strength, fatigue resistance, wear resistance and electrical properties of all 10
Good points, can be -40 ℃ - 100 ℃ between the long-term use.
By molecular chain structure is different, can be divided into both POM POM and acetal copolymer. The former density, crystallinity, melting point are high, but
Poor thermal stability, processing, narrow temperature range (10 ℃), the stability of the pH is slightly lower; the latter density, crystallinity, melting point lower, but hot
Stable, not easily broken down, processing temperature range (50 ℃).
Inadequacy of POM is: by the by acid corrosion, poor weather, poor adhesion, thermal decomposition and softening temperature close to, limited oxygen index
Small. They are widely used:
Automotive: used to make the car axle, planetary gear pads saves copper, and increased service life. Can also be used
It does radiator pipe valve, radiator cover, water pump impeller, gear housing, carburetor housings, gas pedal parts, and the heater
Fans, control rods, various types of switches, bearing bracket, regulator handle, brake and washer pump and other components.
Electronics: power wrench can be used to make shell, switch handles, can also make telephone, radio, tape recorders, video recorders, television
Machine, computer, fax machine parts, timer parts, such as cassette tape recorder.
Machinery and equipment: for making all kinds of gears, rollers, bearings, conveyor belts, springs, cams, bolts, all kinds of pump, shell, leaf
Wheel bearing friction and other mechanical equipment, structural components.
Other areas: for the production of tap, frame windows, wash basins, water tanks, curtain pulley, water shell and pipe fittings, etc..
In addition, it can be used in aerosol packaging, pipeline, submerged in the oil components and standard resistance panels.
