Neuthane 801 NG C53 (2 Component) MDI - PTMEG Quasi Systems 60-95 Shore A

Properties

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

 

  • a high level of physical properties
  • good dynamic performance
  • good hydrolysis resistance
  • high resilience
  • 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 50-60°C 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 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, preheated to the recommended temperature
  • Cure as recommended

 

Processing

  • 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

  • Solvents - ester based systems should be considered: Neuthane 200 [TDI], 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
