Cologne, Germany – Lanxess AG has developed a low free MDI-based cast urethane, which can be processed via injection moulding.
Adiprene C930 is based on a low-free-monomer prepolymer, with viscosity lower than a conventional prepolymer, that delivers improved ‘industrial hygiene,’ Lanxess announced 4 June.
With high output rates and more complex geometries offered by injection moulding, Lanxess said the process was “highly efficient and cost-effective.”
The German materials supplier highlighted an application for the elastomer involving an injection moulding process developed by Autox.
The Korean company, it said, recently launched an injection-moulded vibrating screen for the mining industry, in which production time was cut to five minutes – from 35 minutes with pour casting.
The cast PU also offers “outstanding” abrasion resistance and rebounding properties, which will allow the screen to withstand highly demanding applications in mining, added Lanxess.
Citing field testing, Lanxess said its new cast PU can improve lifetime of the screen by up to three times than the market high quality reference.
