LOW DENSITY PE SHEET<br />
Low density polyethylene (LDPE) is more fl exible than HDPE, which makes it a good<br />
choice for prosthetic devices, most of which are either drape formed or vacuum formed.<br />
Its impact resistance makes it a natural for impact pads, while its easy machinability<br />
makes it a good choice for fabricated parts where chemical and corrosion resistance is<br />
demanded. LDPE is stress relieved and a “natural” color. It is available in 4’ x 8’ sheets<br />
in thicknesses up to 1”.<br />
