Neuthane 100 Series TDI - PTMEG Ether Prepolymers (72 - 95 Shore A)

Properties

The Neuthane 100 series are high performance TDI – PTMEG ether prepolymers designed to produce items for use in arduous application areas.

They offer:

  • a high level of physical properties
  • very good dynamic performance
  • good hydrolysis resistance
  • ease of use
  • low viscosity
  • choice of normal or long pot life grades
  • hardness range from 70A-95A

Typical Applications

  • Wheels (e.g. fork truck, pallet truck and press on bands)
  • High load roller coverings (e.g. steel & paper industry)
  • Mining and quarrying (e.g. screen decks)
  • Hydrocyclones
  • Oil and gas industry (e.g. gaskets)
  • Automotive (e.g. suspension bushes)
  • Pipe-linings
  • Metal Finishing (e.g. vibration bowls)

Processing can be by hand or by dispensing machine

Hand Processing

  • Melt prepolymer at 50-70°C for 12-24 hours (as a guide the grades with the lower NCO value will take  longer to melt than those with higher NCO values)
  • Heat the prepolymer and curative to the recommended temperature
  • Add pigments and Antifoam, as applicable, whilst mixing
  • It is recommended that air be removed from the prepolymer under vacuum prior to addition of the curative
  • Add the curative 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 Considerations

  • Avoid prolonged storage of prepolymers at  elevated temperatures. This will result in low  hardness and lower properties of the cured material
  • Avoid moisture contamination of all materials
  • Part used containers should be flushed with dry  nitrogen and resealed immediately after use
  • ‘LV’ grades available for certain hardness’s  allowing easier processing due to lower viscosity.

Alternatives

  • Solvents/Abrasion - ester based systems should be considered: Neuthane 200 [TDI] or Neuthane 700 [MDI]
  • Humid/Wet - MDI or Aliphatic Isocyanate based systems should be considered: Neuthane 600 [MDI]
    or Neuthane 500 [Aliphatic]
  • Resilience – improvements can be achieved with MDI based systems: Neuthane 600HR

[Prepolymer]

  • Cost – Neuthane 100 [PTMEG/PPG], Neuthane 300
  • [PPG] or Neuthane 200 [Ester] can be considered

Neuthane 100 Series TDI - PTMEG/PPG Ether Prepolymers (82 - 95 Shore A)

Properties

The Neuthane 100 TDI - PTMEG / PPG ether prepolymers are designed to offer a good level of physical properties at a price advantage over pure TDI – PTMEG systems.

They offer:

  • a high level of physical properties
  • very good dynamic performance
  • good hydrolysis resistance
  • ease of uselow viscosity
  • choice of normal or long pot life grades
  • hardness range from 70A-95A

Typical Applications

  • Wheels (e.g. pallet truck)
  • Medium load roller coverings (e.g. conveyor rollers for the steel industry)
  • Mining and quarrying (e.g. scraper blades)

Processing can be by hand or by dispensing machine

Hand Processing

  • Melt prepolymer at 50-70°C for 12-24 hours
  • Heat the prepolymer and curative to the recommended temperature
  • Add pigments and Antifoam, as applicable, whilst mixing
  • It is recommended that air be removed from the prepolymer under vacuum prior to addition of the curative
  • Add the curative 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 prolonged storage of prepolymers at elevated temperatures. This will result in low hardness and lower properties of the cured material
  • Avoid moisture contamination of all materials
  • Part used containers should be flushed with dry nitrogen and resealed immediately after use
  • The development of cure is longer than for pure PTMEG systems so in mould times may need to be extended. Rapid temperature changes during the early stages of cure may result in splits forming in large components.

Alternatives

  • Solvents - ester based systems should be considered: Neuthane 200 [TDI] or Neuthane 700 [MDI]
  • Humid/Wet - MDI or Aliphatic Isocyanate based Systems should be considered: Neuthane 600 [MDI] or Neuthane 500 [Aliphatic]
  • Dynamic – pure PTMEG systems should be considered: Neuthane 100 [TDI] or Neuthane 600 [MDI]

Neuthane 2100 Series Low Odour TDI - PTMEG Ether Prepolymers (85 Shore A - 47 Shore D)

Properties

The Neuthane 2100 series are low-odour, high perfomance TDI – PTMEG ether prepolymers designed to produce items for use in arduous application areas.

They offer:

  • low levels of free isocyanate
  • a high level of physical properties
  • very good dynamic performance
  • good hydrolysis resistance
  • ease of use
  • low viscosity
  • hardness range from 85A-95A*

* Lower hardness can be obtained with Neuthane CA curatives. (Details available upon request)

Typical Applications

  • Wheels (e.g. fork truck, pallet truck and press on bands)
  • High load roller coverings (e.g. steel & paper industry)
  • Mining and quarrying (e.g. screen decks, pipe lining)
  • Hydrocyclones
  • Oil and gas industry (e.g. gaskets)
  • Automotive (e.g. suspension bushes)
  • Metal Finishing (e.g. vibration bowls)
