Hot Cast Prepolymers
Hot Cast urethane prepolymers are used in the most rigorous applications where the highest performance is required. Processing of these polyurethane elastomers generally involves heated components and tooling along with a hot post-cure to optimize properties. In most cases, low to medium cost mixing equipment and tooling are adequate. Our Hot Cast polyurethanes are used extensively in mining, industrial tires, and metal manufacturing markets.
TDI PPG: these products are generally characterized by: ease of processing, room-temperature liquidity and low viscosity
TDI/PTMG: these products are generally characterized by: robust processing, hydrolytic stability, low-temperature flexibility and excellent dynamic load-bearing capability
TDI/ESTER: these products are generally characterized by: resistance to cut/tear, oils & solvents and high temperatures
TDI/CAPROLACTONE: these products are generally characterized by: a unique combination of chemical resistance, high cut/tear properties and good hysteretic performance
MDI/PPG: these products are generally characterized by: ease of processing, room-temperature liquidity, low viscosities and use of non-MBCA curatives
