Polyurethane (PU) or Urethane from Allplastics Engineering , is a thermoset elastomer available in a wide range of shore hardnesses from extremely soft to hard. The hardness is a consequence of the molecular structure of Polyurethane, not by the addition of fillers.Polyurethane has excellent resistance to abrasion, oils, various chemicals, solvents, and oxidation: while maintaining high tensile strength and resilience. Polyurethane is cast (poured) into shapes and Allplastics offers a machining service on this unique elastomer which combines the elasticity of rubber with the advantages of plastics.
Features of Polyurethane:
- Polyurethane is corrosion resistant
- Polyurethane contains good bonding and moulding capability
- Remains flexible at low temperatures
- Superior abrasion and tear resistance
- High load bearing capacity
- Polyurethane offers a high impact resistance
- Fatigue resistant
- Noise reduction
- Non marking of painted surfaces
Polyurethane can be used in a number of applications, including:
- Pump Impellers
- Bumpers and Isolators
- Industrial rollers and wheel coatings
- Hydraulic Seals, Wipers, Washers
- Conveyor drive and idle rollers
- Scraper blades
Polyurethane comes in three differing specifications, including sheets from 10mm Dia to 150mm; rods from 3mm thick to 50mm and tubes made to order.
