Middlebury, Connecticut - Chemtura Corp. claims to have recast the rules of polyurethane manufacturing with its new Adiprene Duracast two-component urethane system.
The group is excited about the ability of this "groundbreaking" advance to enable customers to pour parts of all sizes, "including some of the largest, most intricate parts ever," with greater ease, toughness and durability than ever before, said a 15 Aug release from Chemtura.
"Adiprene Duracast demonstrates total improvement in process, product and cost," said Matthew Hellstern, vice president of Chemtura Urethanes, in the company statement. "With the flexibility of making large or small parts with fast or slow cures, customers may now be able to capitalise on applications that were once too difficult to produce with cast urethane or rubber."
According to Chemtura, the two components of Adiprene Duracast, with its proprietary curative, offer high performance through superior phase segregation.
With no MOCA (4,4-methylene bis 2-chloroaniline) or BDO (butanediol) curatives, Chemtura says Adiprene Duracast delivers "significantly longer pot life and quick demould times." As a result, manufacturers gain tighter control over ratio and waste - and higher productivity at lower cost.
No TDI (toluene diisocyanate) and no MOCA also means improved environmental health and safety, especially in handling. Chemtura says workers do not have to deal with dust or melting issues, describing the four-step process as easy to learn, reducing human error while raising quality standards.
