Neuthane 801 XP  (3 Component Extra High Performance) MDI - PTMEG Quasi Systems (60A - 75D)

Properties

The Neuthane 801XP series are high performance MDI – PTMEG ether quasi sytems designed to produce items for use in arduous application areas.

They offer:

  • a very high level of physical properties
  • very good dynamic performance
  • good hydrolysis resistance
  • high resiliance
  • low viscosity
  • low process temperatures

Typical Applications

  • Wheels (e.g.fork-truck, pallet-truck and press-on bands)
  • In-line roller-blade wheels
  • Mining and quarrying (e.g. screen-decks, scraper-blades)
  • Hydrocyclones
  • Automotive (e.g. suspension-bushes)
  • Roll covering

Processing can be by hand or by dispensing machine

Hand Processing

  • Melt ISO component at 30-40°C, POLYOL component at 50-60C° and BD at 40°C for 12-24 hours.
  • 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 the addition of the curative.
  • Add all components and thoroughly mix ensuring that no unmixed material is left on the container sides [if necessary the mix can be transferred to a second clean container and mixed again].
  • Remove air under vacuum.
  • Cast into moulds, pre-heated 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 completley liquid and thoroughly mixed prior to use.
  • Due to the exothermic nature of the system, larger mixes will have a shorter pot-life.

Alternatives

  • Solvents - ester based systems should be considered: Neuthane 200 [TDI] or Neuthane 700 [MDI prepolymer], or Neuthane 802 [MDI quasi].
  • Cost – Ester systems can be considered Neuthane 700 [MDI prepolymer] or Neuthane 802 & 803 [MDI quasi].
  • Temperature - Neuthane 100 [TDI - PTMEG] or Neuthane 500 [Aliphatic Isocyanate] based systems may be considered.
