POM / Polyoxymethylene Granules / Paraformaldehyde

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 **0 °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 (****5% crystalline) with a melting point of **5° Celsius
 
POM copolymer has a slightly lower melting point of **2 - **3° Celsius.
 
POM advantages
 
High abrasion resistance
 
Low coefficient of friction
 
High heat resistance
 
Good electrical and dielectric properties
 
Low water absorption
 
 4.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.
