- Product Characteristics
It is easy to machine, has very good electrical insulation properties and is resistant to most dilute acids, cleaning agents and some solvents. Acetal homopolymer (Delrin®) sheet has a lower thermal expansion rate than Acetal copolymer. PAR can supply genuine Delrin® plastic sheet upon request.
- Key Features
- Temperature: Up to +110°C (+150°C short term).
- Good sliding properties.
- Offers enhanced mechanical strength, hardness and resistance to creep than acetal copolymer.
- Very good electrical insulation properties.
- Improved temperature resistance compared to acetal copolymer.
- Highly machinable.
