PITTSBURGH—Lanxess' Adiprene C930 cast urethane has been used by Autox in an injection molding process.
Autox, a South Korean company, developed a production process allowing cast polyurethane to be injection molded, according to a Lanxess news release. It launched a new vibrating screen for the mining industry made from Adiprene, a low free MDI-based cast urethane.
The process combines the processing advantages of injection molding with properties of cast urethane, Lanxess said.
Adiprene LF prepolymer fits with the injection molding process, given that its viscosity is lower than that of a conventional prepolymer. It provides industrial hygiene as well as ease of processing, Lanxess said.
The Adiprene C930 mining screen features excellent abrasion resistance and rebounding properties, improving the lifetime and screening efficiency of the part. The lifetime of the screen can be up to three times longer than the market high quality reference, according to Lanxess. Results of the caprolactone-based technology have been supported by field testing. It allows less downtime in the mine operation leading to maintenance savings.
The new production process allows use of cast PU prepolymers, to increase performance and easier molding of complex shape parts as the pressure needed for the injection reaches part details, Lanxess said. It also provides better quality consistency, leading to both fewer trimmings and less waste from reduced scrap.
Both companies are confident that other applications can benefit from the production process development, Lanxess said.
