Cheap, good chemical resistance. High impact strength at low temperatures. Excellent electrical properties. Can be processed by all conventional methods. Can be transparent in thin film form.
Disadvantages
Low strength, stiffness and maximum operating temperature. Flammable. Poor UV resistance. High gas permeability ( particularly CO2 ). Susceptible to environmental stress cracking.
Applications
Chemically resistant fittings, bowls, lids, gaskets, toys, containers, packaging film, film liners, squeeze bottles. Heat-seal films for metal laminates. Pipe, cable covering, core in UHF cables.
