What is TPU?
Thermoplastic polyurethane: A linear block copolymer with both thermoplastic and elastomeric properties. Physical crosslinking occurs with hydrogen bonding and interactions between the hard blocks of the polymer chains.
Typical TPU Physical Properties
- High abrasion resistance
- High elasticity
- Low temperature and impact performance
- Resistance to oils, greases and solvents
- Good flexibility
- Easily colored
- Recyclable
Typical Castable Urethane Properties
- High abrasion resistance
- Oil resistance
- Tear and cut resistance
- High load bearing
- Extreme weather conditions
