Title: Innovations by Gary L Maechtle
Introduction
Gary L Maechtle is a notable inventor based in West Bend, WI (US). He has made significant contributions to the field of polyurethane foam technology. With a total of 2 patents to his name, his work focuses on enhancing the safety and utility of polyurethane products.
Latest Patents
One of his latest patents is for a flexible polyurethane foam having a low flame spread index. This innovative foam is produced by combining polyol, predominantly diol and/or triol, with polyisocyanate, mainly diisocyanate, in the presence of a foaming catalyst and a blowing agent. By incorporating at least 75% by weight of pentabromoethyl benzene based on the weight of the polyol, a flame spread index of less than 150 can be achieved according to the ASTM test E-162-76. Remarkably, this invention has led to the production of polyurethane foams with a flame spread index of less than 25. Another significant patent involves the creation of polyisocyanate prepolymers from scrap polyester and polyurethane foam. These prepolymers are prepared by combining organic polyisocyanate with polyols derived from waste or scrap polyalkylene terephthalate polymers and organic polyols. The resulting polyurethane products exhibit useful and unexpected properties.
