1.High density Polyethylene (HDPE):  is a highly crystalline non-polar thermoplastic resin produced through the copolymerization of ethylene and a small amount of α-olefin monomer. HDPE is synthesized under low pressure and is therefore also called low-pressure polyethylene. HDPE is mainly a linear molecular structure and has little branching. It has a high degree of crystallization and high density. It can withstand high temperatures and has good rigidity and mechanical strength and anti-chemical corrosion.

HDPE applications, including film, blow-molding, extrusion molding, injection molding, pipes, wire & cable and base material for producing chlorinated polyethylene.

 

2. HDPE products use grade :  

 

1). HDPE Film Grade

HDPE film grade is widely used in the production of T-shirt bags, shopping bags, food bags, garbage bags, packaging bags, industrial lining and multilayer film. Also used in beverage and medicine packaging, hot filling packaging and fresh produce packaging and anti-seepage film used in hydraulic engineering.

2). HDPE Blow Molding Grade

HDPE blow-molding grade can be used for producing smallsized containers such as milk bottles, juice bottles, cosmetics bottles, artificial butter cans, gear oil barrels and auto lubricant barrels. It can also be used in the production of intermediate bulk-containers(IBC), large toys, floating matters and large and medium-sized containers such as packaging-use barrels.

3). HDPE Filament Grade

The HDPE filament grade is suitable for making packaging film, nets, ropes and small and medium-sized containers

4). HDPE Injection Molding Grade

HDPE injection-molding grade is used for making reusable containers, such as beer cases, beverage cases, food cases, vegetable cases and egg cases and can also be used for making plastic trays, goods containers, home appliances, daily goods use and thin-wall food containers. It can also be used in the production of industrial-use barrels, garbage bins and toys. Through the extrusion and compression molding process and injection molding, it can be used to produce the caps of purified water, mineral water, tea beverage and juice beverage bottles.

5). HDPE Pipe Grade

HDPE pipe grade can be used in the production of pressure pipes, such as pressurized water pipes, fuel gas pipelines and other industrial pipes. It can also be used for making non-pressure pipes such as double-wall corrugated pipes, hollow-wall winding pipes, silicon-core pipes, agricultural irrigation pipes and aluminumplastics compound pipes. In addition, through reactive extrusion (silane cross-linking), it can be used for producing crosslinked polyethylene pipes (PEX) for supplying cold and hot water.

6). HDPE Wire & Cable Grade

HDPE wire & cable grade is mainly used for producing communication cable jacket through fast-extrusion methods.

7). Base Resin for Chlorinated Polyethylene

Base resin for chlorinated polyethylene (CPE) is principally used in the production of chlorinated polyethylene resin. As an excellent modifier and plasticizer to plastics and rubber, chlorinated polyethylene is widely used in the production of plastic doors and windows, PVC pipes and sheets, waterproof coiled material, anticorrosion coating, wires and cables, magnetic material, flameretardant rubber hoses, tapes and modification ABS.
