ESTANE4 Aliphatic TPU or ESTANE* ALR TPU is a high performance, aliphatic thermoplastic polyurethane (TPU) film used for surface protection, which has good mechanical properties, excellent ultraviolet resistance, hightransparency and high gloss. This film has been specifically developed for protecting susceptible areas of cars and other vehicles from damage of stone chips and scuffing.
On the surface, a hard grade of ESTANE* ALR TPU provides stain resistance and self-healing properties. While beneath the surface, the soft grade beneath absorbs impact from stones and road debris.
