High Performance Cast Elastomers |
Neuthane 600 Series |
They offer:
- a very high level of physical properties
- good dynamic performance
- good hydrolysis resistance
- high resilience
- low viscosity
- extended hardness range with CA curatives
Typical Applications
- Wheels (e.g. fork truck, pallet truck and press on bands)
- High performance in-line roller blade wheels (HR grades)
- Roller coverings – wet applications (e.g. steel industry)
- Mining and quarrying (e.g. screen decks, scraper blades)
- Hydrocyclones
- Oil and gas industry (e.g. gaskets)
- Automotive (e.g. suspension bushes)
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
- Ensure 1:4 Butanediol is dry by heating to 115°C and applying vacuum
- 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 - Development of cure is long compared to TDI-MOCA systems.
- Rapid temperature change during the early stages of cure should be avoided.
Alternatives
- Solvents – ester based systems should be considered Neuthane 200 [TDI] or Neuthane 700 [MDI]
- Cost – Ester systems can be considered: Neuthane 700 [MDI Prepolymer] or Neuthane 802 [MDI Quasi]
- Temperature – Neuthane 100 [TDI PTMEG] or Neuthane 500 [Aliphatic Isocyanate]
