High Density Polyethylene (referred to as “HDPE”), also known as low pressure polyethylene, is a kind of High crystallinity, non-polar surface shows a certain degree of translucent shape.PE has excellent resistance to most domestic and industrial chemicals.
Basic properties: High density polyethylene is a kind of opaque white waxy material, the specific gravity is lighter than water, the specific gravity is 0.941~0.960, soft and ductile, but slightly harder than LDPE, but also a little longer, non-toxic, tasteless.
Combustion characteristics: flammable, can continue to burn after leaving the fire, the upper end of the flame is yellow, the lower end of the flame is blue, the combustion will melt, there is liquid dripping, no black smoke, at the same time, emit the smell of paraffin combustion.
Main advantages: acid and alkali resistance, organic solvent resistance, excellent electrical insulation, low temperature, can still maintain a certain toughness.The surface hardness, tensile strength, rigidity and other mechanical strength are higher than LDPE, close to PP, tougher than PP.
Main usages of HDPE granules:
1.Injection products: turnover boxes, bottle caps, barrels, caps, food containers, plates, dustbins, boxes, and plastic flowers.
2.Blow molding products: hollow molding products, such as a variety of series of blow molding barrels, containers, bottles, containing detergents, chemicals, cosmetics, gasoline boxes, daily use products, etc.There are blown film products such as food packaging bags, grocery shopping bags, fertilizer lining film, etc.
3.extruded products: pipe, pipe fittings are mainly used in gas transportation, public water and chemical transportation, such as building materials drainage pipe, gas pipe, hot water pipe, etc. : sheet is mainly used for seats, suitcases, handling containers, etc.
4.Rotation molding: injection molding products such as large containers, storage tanks, barrels, boxes, etc.
5.polyethylene can be processed into film, wire and cable sheath, pipe, a variety of hollow products, injection products, fiber and so on.Widely used in agriculture, packaging, electrical and electronic, machinery, automobiles, daily necessities and other aspects.
You can buy different kinds of HDPE granules from many famous brands at home and abroad from IMRI at a competitive price.
