Global EPP POM C Acetal Copolymer
Categories:	Polymer; Thermoplastic; Acetal (Polyoxymethylene, POM); Acetal Copolymer, Unreinforced
Material Notes:	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.
