Linear Low Density Polyethylene (LLDPE) is an inexpensive polymer with widely favorable mechanical and chemical resistance properties. Tubing made from this polymer is broadly used, particularly for water, chemicals and gases. Unlike with many other plastics, plasticizers are seldom necessary to obtain flexible products, such as tubing. These plastics are highly stable with low toxicity. In fact, many grades can even be used for food-contact and medical applications.LLDPE is a copolymer of ethylene and another longer olefin, which is incorporated to improve properties such as tensile strength or resistance to harsh environments.
