Warm Beer? Thermoplastic Polyurethane to the Rescue!
Polyurethane is great at keeping your summer beverages cold when they’re in the refrigerator or cooler, but what about once you’re drinking them? Beer Blizzard™ is a freezable disk made of thermoplastic polyurethane (TPU) that’s designed to fit into the indentation on the bottom of a soda or beer can. Tucked inside a koozie, it continues to cool your drink from the bottom up.
TPU is an excellent choice for this application because it can be frozen and defrosted thousands of times without cracking, and can be created in any color. Created by Mike Robb and Tom Osbourne, Beer Blizzard™ appeared on the TV show Shark Tank.
