GLS Corp. (McHenry, IL) has introduced a series of thermoplastic elastomers (TPEs) designed to replace polyvinyl chloride (PVC) and silicone-based elastomers in medical applications. Because of a negative safety perception of the material, some manufacturers are seeking alternatives to PVC, especially in the infant care industry. Other manufacturers are seeking alternatives to silicone in order to reduce production costs or increase design flexibility. GLS Corp.'s TPEs feature many of the favorable characteristics of these materials in a solution that is potentially safer than PVC and cheaper than silicone, according to the company. Thermoplastic elastomers are suited for a variety of medical applications, including medical tubing, elastomeric sheet and film products, and medical devices.
