the Flexible PR740

  • Suitable for living hinges and very resistant to torsional and bending forces
  • Limited isocyanate aggressiveness to ensure long mould life
  • High chemical resistance to various aqueous solutions and engine fluids
  • Overall good mechanical resistance with very high elongation at break > 50% and high impact resistance even notched

the cold-curing HPR65

  • Very low exothermic reaction allowing the casting of small to massive parts
  • Can be cured at room temperature or at 70°C for a faster demoulding
  • Very high impact resistance even on a notched specimen
