They offer:
- a high level of physical properties
- good cut and abrasion resistance
- good chemical resistance
- hardness range from 75 - 95A (MOCA)
- hardness range from <40 – 60A (TMP)
Typical Applications
- Medium load roller coverings (e.g. steel industry – dry application areas)
- Roller coverings where lubricants are present (e.g. aluminium manufacture)
- Wheels (e.g. pallet truck)
- Mining and quarrying (e.g. screen decks, scraper blades)
- Oil and gas industry (e.g. gaskets, pipe pigs)
- Press blocks
- Paper converting (e.g. anvil rollers)
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
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]
- Non MOCA – MDI based systems should be considered: Neuthane 700 [Prepolymer] and 802 [Quasi]

Neuthane™ 200 Series TDI - Caprolactone Ester Prepolymers (60 - 95 Shore A)
Properties
The Neuthane 200 Caprolactone series are high perfomance TDI – ester prepolymers designed to produce items for use in arduous application areas. They offer advantages over conventional ester TDI prepolymers in several key areas.
They offer:
- a high level of physical properties
- good cut and abrasion resistance
- good chemical resistance
- good low temperature flexibility
- low viscosity and long pot life*
- improved hydrolysis resistance*
- improved dynamic performance*
- low hardness with MOCA
* Compared with conventional TDI ester prepolymers
Typical Applications
- Medium load roller coverings (e.g. steel industry)
- Roller coverings where lubricants are present (e.g. Dioctyl Sebacate)
- Mining and quarrying (e.g. screen decks, scraper blades)
- Oil and gas industry (e.g. gaskets)
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
- Avoid prolonged storage of prepolymers at elevated temperatures. This will result in low hardness and lower properties of the cured material
- It is important when processing Neuthane 230 that the correct temperatures are maintained. Failure to do so may result in incorrect cured hardness
- Avoid moisture contamination of all materials
- Part used containers should be flushed with dry nitrogen and resealed immediately after use
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]
- Cost – Conventional ester based systems will offer a price advantage: Neuthane 200 [TDI], Neuthane 802 [MDI Quasi]
- Solvents – Conventional ester TDI offer the best performance
