Product Description:

1 Polyoxymethylene (POM), also known as acetal , polyacetal, and polyformaldehyde, is an engineering thermoplastic used in precision parts that require high stiffness, low friction and excellent dimensional stability.

2 Properties

POM is characterized by its high strength, hardness and rigidity to -40 °C. POM is intrinsically opaque white, due to its high crystalline composition, but it is available in all colors. 

POM homopolymer is a semi-crystalline polymer (75-85% crystalline) with a melting point of 175° Celsius 

POM copolymer has a slightly lower melting point of 162 - 173° Celsius.

3 Characters : 

• High mechanical strength and rigidity

• Toughness and high resistance to repeated impacts

• Long-term fatigue endurance

• Excellent resistant to moisture, gasoline, solvents, and many other chemicals of neutral pH

• Excellent dimensional stability

• Good resilience and resistance to creep

• Natural lubricity

• Wide end-use temperature range

• Good electrical insulating characteristics

•  

•   Application:·  Mechanical gears, sliding and guiding elements, housing parts, springs, chains, screws, nuts, fan wheels, pump parts, valve bodies.

• ·  Electrical Engineering: insulators, bobbins, connectors, parts for electronic devices such as televisions, telephones, etc.

• ·  Vehicle: Fuel sender unit, Light stock (including shifter for light, turn signal), power windows, door lock systems, articulated shells.

  ·  Model: Thin, later claimed Modellbahnen parts, such as bogies and handle bars. POM breaks under load slightly less than ABS, but in bright translucent colors, and not paintable.

  ·  Medical: insulin pen, Metered dose inhalers (MDI)

  ·  Furniture: hardware, locks, handles, hinges, or even curtains roles.

  ·  Construction: Structural Glass - pod holder for point

  ·  Packaging: aerosol cans, vehicle tanks.

  ·  Sports: Paintball accessories. It is often used for machined parts of paintball markers that do not require the strength of aluminum, such as handles and reciprocating bolts. POM is also used in airsoft guns, in order to reduce the noise of the piston.

  · Clothing: zippers.
