Cologne, Germany – Lanxess has launched a hot cast, cold cure system for PU Elastomers based on its MDI ether prepolymer and a room temperature curative. The company said this can save energy and CO2 emissions.
The system cures at ambient temperatures, enabling processors to turn off hot tables or ovens. This significantly reduces the risk of operator burns. Turning off heating systems can lead to energy savings between 40% and 50% compared with earlier processes.
Using a new MDI ether-based prepolymer also makes it easier to manufacture larger complex parts such as mining pipelines. Lanxess said that with earlier technology, this was challenging, and productivity was limited because plants were used for a long time.
Gerald King, head of application technology for EMEA at Lanxess, said: 'Sustainability has increasingly come into focus within the last decade and, by driving clear energy saving, we offer our customers a more sustainable product.’
King is scheduled to present a paper about this development at UTECH Europe in Maastricht in the CASE session on the afternoon of 16 November.
