Title: Glenn C. Castner: Innovator in Thermoplastic Foam Technology
Introduction
Glenn C. Castner, an esteemed inventor based in Victor, NY, has made significant contributions to the field of thermoplastic foam technology. With a total of 11 patents to his name, Castner has developed innovative methods and materials that enhance the performance and environmental sustainability of thermoplastic foams.
Latest Patents
One of Glenn C. Castner's latest significant inventions pertains to reduced-VOC (volatile organic compounds) and non-VOC blowing agents used for manufacturing expanded and extruded thermoplastic foams. This innovative process involves preparing an expandable polymeric formulation that includes a thermoplastic polymer and a specific blowing agent blend. The process further entails forming this formulation into expandable beads, which are then expanded to produce a thermoplastic polymer foam article.
The blowing agent blend utilized in this process is comprised of methyl formate, hydrocarbons, and either carbon dioxide or 1,1,1,2-tetrafluoroethane (HFC-134a). This blend is notable for having a higher effective volatility than that of methyl formate alone. Additionally, his invention provides a method for producing thermoplastic polymer foams that are dimensional and stable, with improved resistance to flame spread due to the incorporation of co-blowing agents alongside methyl formate.
