Sustarin® H - Homopolymer
SUSTARIN®-H is an Acetal Homopolymer which was first commercialised by DuPont de Nemours in 1960 and trademarked as DELRIN®.
It is a crystalline thermoplastic made by the polymerisation of formaldehyde resulting in a material that has a slightly higher stiffness, tensile strength and creep resistance to SUSTARIN® C Copolymer.
Its limited resistance to long-term use in steam and boiling water restricts the use of SUSTARIN® H.
Semi-finished parts made from SUSTARIN®-H can be drilled, turned and milled in the same way as Sustarin®-C.
SUSTARIN®-H Acetal Homopolymer can be characterised by the following properties:
- High mechanical strength and stiffness
- Excellent dimensional stability
- Good impact strength
- Good wear resistance
- Good sliding properties
- Low water absorption
- Resistant to fuels and solvents
- Meets EU & FDA requirements for food contact applications
- Is not self extinguishing and burns with a clear flame
Fields of application: gears, sliding parts, bearings, impellers, pump parts, valve parts, feed screws, food industry components, bushes, cams.
