Polyolefin plastic, a polymer material prepared by polymerization or copolymerization of one or more type olefin.
Polyolefin plastics are the largest and most used polymer materials in the world, mainly including polyethylene (PE), polypropylene (PP), POE, EVA, MMA and other advanced olefin polymers.
Applications of Polyolefin plastic
Automotive industry:
With the requirements on automobile lightweight and automobile consumption reduction policies, it has become a development trend to replace steel with plastic to reduce automobile quality. Modified polypropylene is the plastics with the largest proportion in automotive plastics, which applied in instrument panel, door panel, exterior trim, bumper, fender, etc..
Polyolefin films
Low density polyethylene film has good transparency and a certain tensile strength, widely used as agricultural film and a packaging materials for food, medicine, fertilizer, industrial products .
Home appliances and construction area
HDPE injection molding material is usually used as the shell of household appliances. HDPE pipe has high strength, so it used as building underground laying pipe.
Excellent performance of Polyolefin plastic:
Low density. The density of polyolefin plastic is usually between 0.83-0.96 g/cm³, that’s also why it’s been selected as Top1 material in Automotive industry.
Good physical and chemical comprehensive performance.
Easy to be pigmented, polyolefin can be made into a variety of color products according to request.
Well processing performance. It can be processed into tube, plate, film and fiber by extrusion, blow molding and injection process.
Some of the polyolefin defects you may encounter:
Polyolefin contains weak double bonds and defects. When catalyzed by high temperature, light, O3, or metal ions, these weak bonds become the breakthrough of aging and the starting of chemical reactions, then triggering a series of reactions which change the molecular structure of the polymer. Thus, Polyolefins will occur discoloration, hardening brittle and crack. At the same time, product’s mechanical properties will reduce, some application value will also lose.
