Successful solution for South West Metallurgical Services

South West Metallurgical Services based near Penzance Cornwall(UK) design, manufacture and supply Spiral Concentrators to the coal, mineral and environmental industries.

They were looking for a hand-mixable cast polyurethane, Shore A 86, for the high wear components of their Spiral Concentrator.
Spiral wear components are required to withstand a continuous flow of highly aggressive slurries 24 hours a day, seven days a week, over many years of service.

SWMS are using high-performance NOTEDOME Neuthane 801NG – A quasi PTMEG polyether-based MDI system for their Spiral Concentrators.

Rob Davies of SWMS says “we are using the Neuthane 801 NG system with the CAT044 catalyst and find that at 35 – 40°C material temperature and 75 – 80°C mould temperature we can pour any of our moulds (from 0.5kg up to 4kg), and get the required physical properties”.

Pot life is 8 – 12 min and demould time about 50 minutes – increasing the material temperature from 30°C has helped with mixing, de-gassing and pouring”.

Rob added – “We are very pleased with how the Neuthane 801NG system has worked and its resistance to the aggressive slurries.”
