Effect of Rapid Heating Cooling Molding on Polycarbonate-based Material Properties


Jessica Boyer, application development engineer, Polycarbonates, Covestro LLC, presented: “The Effect of Rapid Heating Cooling Molding on Polycarbonate-Based Material Properties”.

Boyer shared results from a comprehensive study that compares conventional injection molding (CIM) and rapid heating cooling molding (RHCM) by examining the physical properties of parts produced using polycarbonate and polycarbonate blends. She discussed how, when using these materials, RHCM technology has been shown to enhance surface appearance of the final part, while increasing weld-line strength and flow length during the injection molding process.

New Resin for Liquid Cooled Modules in Electric Vehicle Battery Packs (EVBPs)


Rudy Gorny, senior principal scientist, Covestro LLC, presented “New Resin for Liquid Cooled Modules in Electric Vehicle Battery Packs (EVBPs).”

During his presentation, Gorny discussed how a new polycarbonate blend from Covestro can be used for liquid cooled modules in EVBPs. These components undergo rapid charging and discharging, generating large amounts of heat. Pumping coolant directly through molded-in cooling channels inside the battery module is a more cost-effective approach but requires a flame-retardant resin with high hydrolytic stability. Gorny shared test results that demonstrate how this new polycarbonate blend can meet the needs of liquid cooled EVBPs.

Accounting for Differences in Modulus and Stress Relaxation Behavior in Plastics Undergoing Chemical Resistance Testing


Mark Yeager, field engineering manager, Covestro LLC, presented “Accounting for Differences in Modulus and Stress Relaxation Behavior in Plastics Undergoing Chemical Resistance Testing”.

Yeager discussed how chemical resistance testing via strain fixtures ranks resistance based on the maximum strain at which the plastic can resist an applied strain without loss of mechanical integrity or appearance. While this comparison works well for materials within a family of plastics, such as unfilled polycarbonates, it can be misleading when comparing materials that differ in stiffness and stress relaxation properties. In this presentation, Yeager covered how manufacturers can adjust for these differences to yield a more realistic chemical resistance ranking for most applications.
