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 mechanical parts. Key characteristics: - High mechanical strength and rigidity
- High impact strength and creep resistance
- Excellent dimensional stability and machinability
- Low moisture absorption
- Good electrical insulating and dielectric properties
- No centreline porosity in copolymer grades
- Suitable for food contact
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. |
