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

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.

Features

  • 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

  • Long pot life enables 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

  • Pails or Drums must be melted and rolled so material is fully mixed before use
  • 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

  • It is recommended to store Neuthane™ 801 ISO XP within the temperature range of 20-30 °C. At lower temperatures can deteriorate, because of the partial crystallisation of its 4,4'-methylenediphenyl diisocyanate content. At higher temperatures above 30 °C, it is not recommended since discolouration and formation of insoluble solids (dimerization) may occur which can lead to a viscosity increase and a decrease of NCO content.
  • Recovery Procedure: If partial or entire freezing occurs, it is recommended to rapidly melt out Neuthane™ 801 ISO XP at 70°, typically for 16 hours or overnight.

Features

  • 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
  • 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

  • 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
