Material Overview: POM C Acetal Copolymer is highlighted for its strength, stiffness, and wear resistance. It is suitable for food contact and medical applications due to its low moisture absorption and porosity-free nature. It offers superior resistance to hydrolysis, strong alkalis, and thermal-oxidative degradation compared to acetal homopolymer.

General Properties: The material is available in white, black, and blue colors. It has a density of 1.410 g/cm³ and minimal moisture absorption.

Mechanical Properties: Key mechanical properties include a tensile strength of 70 MPa, E-modulus of 2700 MPa, and compressive strength of 110 MPa. It also features a flexural strength of 80 MPa and an Izod impact strength of 7.20 KJ/m².

Thermal Properties: The melting temperature is 170°C, with a maximum continuous service temperature of 90°C. The material has a thermal conductivity of 0.31 W/m.°C.

Electrical Properties: The dielectric constant is 3.8 at 1MHz, with a dielectric strength of 16.5 kV/mm. Volume resistivity is 1x10¹³ ohm.m.

Flammability: The material is rated HB according to IEC 60695-11-10:2003-08.

Catalog excerpts

Acetal Copolymer The Copolymer grade is the ideal combination of strength, stiffness and wears 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.
