LDPE
Low Density Polyethylene (LDPE) is a soft, flexible, lightweight plastic material. It is a corrosion resistant material that sustains low moisture permeability. Additionally, it has a relatively low working temperature and low tensile strength. Typical applications include orthotic and prosthetic devices, impact pads, and hinges
