New TPEs Better Than PVC
Medalist® compounds for low-temperature film are 70% as dense as PVC, with a typical specific gravity of 0.90.
At the same time they exhibit greater toughness in cold-storage applications, with brittle points as low as -60 °C, as against -40 °C for PVC.
This greater toughness introduces the possibility of down-gauging from standard thicknesses or replacing multi-layer structures with monolayer films.
The new Medalist compounds exhibit tensile and tear strength properties comparable to those of PVC and better moisture barrier.
