ACETAL COPOLYMER & HOMOPOLYMER (Delrin)
| Characteristics | Typical Applications |
|---|---|
| High crystalline with low water absorption | Pump Housings |
| Good dimensional stability & creep resistance | Impellers |
| Easy to machine to tight tolerances | Gears |
| Good electrical insulator | Bearings |
| Domestic Appliances | |
| Electrical Components | |
| Valves |
Both Homopolymer & Copolymer grades are similar in their overall balance of properties, although each shows some difference from the other in detail. In general, the mechanical properties of the Hompolymer are slightly superior to the Copolymer, although the latter has a higher continuous operating temperature. Delrin AF is Acetal Homopolymer containing PTFE fibre, uniformly dispersed to give a material with improved wear and low friction properties. Glass Filled is Acetal Homopolymer with glass fibre to enhance wear properties.
