HDPE
High Density Polyethylene (HDPE) is leveraged in applications where great impact and tensile strength are needed. It is easy to fabricate, absorbs little moisture, and is corrosion resistant. Typical applications include water and chemical tanks, light duty wear strips and chain guides, and orthotic and prosthetic devices.
