Polyacetal (POM C)

Polyacetals are highly crystalline thermoplastics, characterised by their high mechanical strength, rigidity and impact resistance. Acetal absorbs very little moisture, enabling the product to maintain constant physical properties in a variety of changing environments. POM exhibits excellent dimensional stability and is ideally suited to close tolerance of mechanical parts.

Key characteristics

High mechanical strength and rigidity
High impact strength and creep resistance
Excellent dimensional stability and machinability
Low moisture absorptlon
Good electrical insulating and dielectric properties
No centreline porosity in copolymer grades
Suitable for food contact

Standard extruded

Polyoxymethylene (Polyacetal) grades):

POM C (Acetal copolymer, natural, black, various)
The copolymer grade is the ideal combination of strength, stiffness and wear resistance. It absorbs very little moisture, is easily machinable and is genuinely porosity-free, making it the preferred grade for food contact and medical applications. The product exhibits an elevated resistance to hydrolysis, strong alkalis and thermal-oxidative degradation when compared to acetal homopolymer.

POM CPE (Acetal copolymer + PE) (blue)
Self-lubrication is achieved by the incorporation of ultra-high molecular weight polyethylene to the copolymer grade, improving sliding, dry-running and abrasion resistance properties. The material also has extremely low moisture absorption, helping to improve component dimensional stability.

POM C GF (Acetal copolymer + 30% glass ﬁbre) (white, black)
This copolymer grade is reinforced with glass ﬁbre to achieve greater mechanical strength, rigidity and dimensional stability. The material also exhibits higher heat resistant properties.

POM H Acetal Homopolymer (Delrin®) (white, black)
The homopolymer grade exhibits slightly higher mechanical properties, illustrated in the hardness, rigidity and creep resistance. The material also demonstrates elevated wear resistance and has a lower thermal expansion rate than acetal copolymer.

POM HT Acetal Homopolymer + PTFE (Delrin®) (brown)
The inclusion of Teﬂon® ﬁbres uniformly dispersed in the compound improves the products frictional and sliding capabilities, improving wear and stick/slip behaviour.
