Neuthane 802-NG (3 & 4 Component) MDI - Ester Quasi Systems (55 - 95 Shore A)

Properties

The Neuthane 802 series are high performance MDI - ester quasi systems designed to produce items for use in arduous application areas.

They offer:

  • a high level of physical properties
  • good cut and abrasion resistance
  • good chemical resistance
  • higher levels of physical properties at low end of
    the hardness range compared to TDI systems
  • low process temperatures

Typical Applications

  • Wheels (e.g. pallet truck)
  • Mining and quarrying (e.g. screen decks, scraper blades)
  • Oil and gas industry (e.g. gaskets, pipe pigs)
  • Automotive (e.g. suspension bushes)
  • Concrete Industry (e.g. moulds for decorative slabs and walls)

Processing can be by hand or by dispensing machine

Hand Processing

  • Melt ISO component at 45°C, POLYOL components at 55°C for 12-24 hours (Excluding Plast NG for4 component system)
  • Ensure components are completely liquid and thoroughly mixed prior to use
  • Bring all components to the recommended process temperature.
  • Add pigments and Antifoam (as applicable) to the polyol component whilst mixing
  • It is recommended that air be removed from the ISO component under vacuum prior to addition of the curative
  • Add all components and thoroughly mix ensuring that no unmixed materialis left on the container sides (if necessary the mix can be transferred to a
    second clean containerand mixed again)
  • Cast into moulds, preheated to the recommended temperature
  • Cure as recommended

Processing Considerations

  • Avoid moisture contamination of all materials.
  • Part used containers should be flushed with dry nitrogen and
    resealed immediately after use
  • It is vital to ensure that both components are completely liquid and
    thoroughly mixed prior to use
  • Due to the exothermic nature of the system, larger mixes will have a shorter pot life

Alternatives

  • Humid/Wet - PTMEG ether based systems should be considered: Neuthane 100 [TDI], Neuthane 600 [MDI] or Neuthane 500 [Aliphatic]
  • Dynamic/Resilience - PTMEG ether based materials should be considered: Neuthane 100 [TDI], Neuthane 600 [MDI] or Neuthane 801 [MDI Quasi]
  • Temperature – Neuthane 100 [TDI PTMEG] or Neuthane 500 [Aliphatic Isocyanate] systems may be considered
