what material is a hard hat made of
What materials are hard hats made from? Hard hat shells can be manufactured in a variety of materials. Most are made with some form of thermoplastic; either polyethylene (HDPE) or polycarbonate. They use these materials because they are lightweight, strong, and easily molded. They can, however, be made with other materials such as fiberglass, resin-impregnated textiles, or aluminum. Hard had suspensions will often consist of strips of woven nylon webbing and bands of molded HDPE, nylon, or vinyl.
