High density polyethylene for injection molding, film, pipe, blow molding,
HDPE for blow molding, HDPE for film, HDPE for injection moldin, HDPE for pipe,

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.

High density polyethylene resin products are granule or powder, no mechanical impurities. The products are cylindrical particles with good mechanical properties and excellent processing properties. They are widely used in the production of extruded pipes, blown films, communication cables, hollow containers, accommodation and other products.

Features

Application

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. Sinopec produces a full grade of HDPE, which cover all fields of HDPE applications, including film, blow-molding, extrusion molding, injection molding, pipes, wire & cable and base material for producing chlorinated polyethylene.

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 small sized 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 aluminum plastics compound pipes. In addition, through reactive extrusion, 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.

High density polyethylene (HDPE) has good strength, good toughness, good rigidity, waterproof and moisture-proof,

Heat and cold resistance, corrosion resistance, non-toxic, non-absorbent and other advantages, so in blow molding, injection molding, film,

It plays an important role in pipe, and is mainly used in pipe, automobile, chemical and other fields.

With the formation of industry trends such as “replacing steel with plastic and wood with plastic”, HDPE is used as a high-performance material

Material gradually replace traditional materials, market demand continues to rise, the industry development prospects are better.

HDPE is mainly used in injection molding, film, pipe, blow molding four major fields in the United States

HDPE gas pipe is occupied about 88% of the total demand for gas pipe, but its HDPE gas in our country

The demand for pipes is small, only accounting for about 15% of the gas pipe market. HDPE mainly in our country

Used in injection molding and blow molding field, injection molding is the largest consumption area of HDPE, accounting for about

32%, followed by blow molding accounted for about 23%, pipe and film field accounted for relatively low, mainly its

Production capacity is in short supply and products depend on imports.
