Polyolefins polyethylene blow molding

Polyolefin - Polyolefins are a large class of carbon-chain elastomeric and thermoplastic polymers usually prepared by addition (co)polymerization of olefins or alkenes such as ethylene. The most important representatives of this class are polyethylene and polypropylene. There are branched and linear polyolefins and some contain polar pendant groups or are halogenated. Unmodified polyolefins are characterized by relatively low thermal stability and a nonporous, nonpolar surface with poor adhesive properties. Processed by extrusion, injection molding, blow molding, and rotational molding. Other thermoplastic processes are used less frequently. This class of plastics is used more and has more applications than any other. Also called olefinic resin, olefinic plastic. 

Blow-molded polyolefin containers, cisterns, and bottles can be made of polypropylene, low and high density polyethylene, and their copolymer. These vessels are used for the packaging, storage, and transport of fluid, viscous, and powdered products such as chemicals, intermediates for synthesis, oil products, detergents, paints, water, food products, drugs, cosmetics, and so on.
