Application
Polyoxymethylene, commonly known as POM, it is a thermoplastic engineering plastics with high melting point and high crystallinty, which is very suitable for machinning work on automatic lathe, especially for precision component manufacturing.
Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE), it has extremely long chains, with a molecular mass usually between 3.5 and 9.6 million. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening inter molecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made.

Frequently Asked Questions
What is POM and what makes it suitable for precision components?
Polyoxymethylene (POM) is a high-melting-point, high-crystallinity thermoplastic engineering plastic. Its excellent dimensional stability and rigidity make it ideal for machining work on automatic lathes for precision component manufacturing.
What is UHMWPE and why does it have high impact strength?
Ultra-high-molecular-weight polyethylene (UHMWPE) has extremely long molecular chains with a molecular mass between 3.5 and 9.6 million. These long chains transfer load more effectively to the polymer backbone, giving it the highest impact strength of any thermoplastic made.
What sizes and thickness ranges of POM Sheets are available?
Standard available sheet sizes are 1000x2000mm and 620x1200mm, with thickness options ranging from 1mm up to 200mm and lengths of either 1000mm or 2000mm.
Can I get a sample of the POM sheet for evaluation?
Yes, free samples can be provided for quality checks to help ensure the material meets your engineering specifications.
What chemical resistance ratings does POM offer?
According to the physical data, POM offers positive resistance (+) to acids, alkalis, carbonated water, aromatic compounds, and ketones.
What is the thermal resistance performance of POM?
POM has a melting point of 165ºC, a short-term heat resistance of up to 140ºC, and is capable of withstanding continuous heat up to 115ºC.
