Proteus™ LDPE lightweight shapes possess a great combination of excellent impact resistance, superior chemical and corrosion resistance, easy machinability and cleaning capabilities and zero moisture absorption. As an extremely flexible grade of low-density polyethylene, components made from Proteus™ LDPE are often used in prosthetic device applications that require drape forming or vacuum forming processes. Due to its flexibility and range of other performance properties, Proteus™ LDPE excels in a variety of industrial and medical environments such as thermoformed parts, impact pads, hinges and die pads.
