Homopolymer
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.
Key features
- 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
