Chem-Trend introduces new Pura® products for Polyurethane Rigid Foams and Polyurethane Rigid and Semi-Rigid Energy Absorbing (EA) Foams

Howell, January 2006 - Chem-Trend has recently added a number of new and innovative mold release agents into its Pura 15000 and Pura 16000 Series of ready-to-use and dilutable concentrate release agent products for the Polyurethane Industry. Applications for their use span the market segments of rigid foams, and rigid and semi-rigid energy-absorbing (EA) foams.

These products were developed using new proprietary dispersion chemistries and technologies that were specifically designed to give excellent release and surface aspect, as well as low build-up, in Polyurethane production molding operations. This has allowed mold-cleaning frequency to be reduced. According to Dr. Edward F. Cassidy, Chem-Trend Business Development Director for Polyurethanes, these products can be used as supplied, or diluted up to one part mold release agent to five parts carrier solvent in some situations, prior to application. Typical molding applications for these products include rigid foam parts and rigid and semi-rigid energy absorbing (EA Foam) articles. "These products contain a unique blend of components that provide good barrier properties and excellent film formation with rapid evaporation of the carrier solvent," says Dr. Cassidy. "They maintain superb release characteristics over a very broad molding temperature range, typically from 90-160ºF (32-71ºC), and are very robust products." he continues. Chem-Trend has also developed numerous product variations of this unique material that contain higher active component concentrations, higher flash points and the ability to employ surface-improving additives to allow for more flexibility in meeting specific customer requirements.

Extensive field-testing and commercialization efforts using these materials have yielded an overwhelmingly positive response from customers, particularly rigid foam and EA foam molded part manufacturers. It has been found that these products can be fine-tuned to allow specific process optimization in production, over a very broad processing range.
