A new line of TPE alloys with high barrier to oxygen and moisture have been launched by GLS Corp., McHenry, Ill., for food, beverage, and medical applications. Oxygen permeation ranges from 2000 to 20,000 cc-mil/m2-day-atm at 23 C compared with 50,000 to 90,000 for standard TPEs. MVTR is about 2.3 to 3.8 g/m2-day at 38 C and 100% RH. GLS claims the materials can provide two to five times longer shelf life than other materials. They can be injection and blow molded and extruded. Translucent grades are available. Hardnesses run from 40 to 90 Shore A.
