Polyurethane castings
Polyurethane is a versatile material that's tough, strong, durable + competitive when compared to a wide range of alternatives including wood, steel, rubber and other engineered plastics.
Material properties that contribute to polyurethane as a preferred choice include:
- Hardness range greater than rubber: from SHORE 10A to SHORE 85D
- Outstanding durability in severe wear applications with high abrasion resistance
- Greater load bearing capacity compared to other elastomers
- High tear resistance
- High shock absorbing capability and impact resistance
- Resists cracking even under repeated flexing.
- Suitable for use in applications under continuous use up to 90°C
- Polyurethane can be formulated to provide protection against a range of chemicals
- Fire retarded formulations are available to meet a range of self extinguishing specifications including FRAS for underground mining applications
- High hardness polyurethanes have a low coefficient of friction that makes them especially suitable in high wear applications.
