Polyester Polyurethane Cast Elastomer Systems

Shore A20 - D87 Hardness

Components : Polyester Polyol Mixture and Polyester or Polyether / MDI Quasi-Prepolymer
                        or Polymeric MDI Isocyanate.

Applications : Where A-Scale and D-Scale Polyurethane elastomers with superior solvent
                         and oil resistance and/or good to excellent tensile and compression
                         properties are required. Higher Hysteresis (Heat Build-up) makes these
                         materials suitable for Non-dynamic applications.
                         Gaskets, Spill dams, Toys,…

Advantages

bullet Superior Solvent and Oil Resistance
bullet Variable Reaction Profile
bullet Hydrophobic Polyol Mix
bullet Variety of Colors

Considerations

bullet Poor Hydrolytic Stability of Elastomer
bullet Low Thermal Resistance
bullet Mediocre Resilience
