AlphaGary Introduces Economical Silicone Replacement
Thermoplastic elastomer compounds for molding and extrusion applications have been launched in North America as a cost-effective replacement for silicone in disposable medical devices. The Evoprene Super G compounds reportedly allow users to benefit from the materials' elasticity and processing ease without sacrificing the critical properties of silicone.
Evoprene compounds combine elasticity and processing ease.
"Evoprene compounds will provide customers in the disposable medical device market with a new, innovative replacement in areas where thermoset silicone typically has been the only available material," announced Robert Gingue, managing director, worldwide, for AlphaGary Corp. (Leominster, MA).
Desirable properties of the styrenic-based TPE materials include their compression set characteristics, temperature resistance, and tensile strength. The compounds, which have been used in Europe for several years in a variety of industrial and consumer applications as well as in regulated industries, can be processed using standard thermoplastic equipment. They generally do not require predrying and are free of halogens.Norbert Sparrow
