purpose

Used in color masterbatch manufacturing (dispersant), plastics and polymers, hot melt adhesives, inks, coatings, cable fillers, lubricants and demoulding agents.

Polyethylene (POLYETHYLENE, PE) is a polymer polymerized by ethylene. The product has been developed for about 60 years. The output of polyethylene in the world ranks first among the five most widely used resins.

Polyethylene is divided into high density polyethylene, low density polyethylene and linear low density polyethylene according to different polymerization methods, molecular weight and chain structure.

Low density polyethylene (LDPE), commonly known as high-pressure polyethylene, because of its low density, the softest material, mainly used in plastic bags, agricultural film, etc.

High density polyethylene (HIGH DENSITY POLYETHYLENE, HDPE) is commonly known as low pressure polyethylene. Compared with LDPE and LLDPE, it has higher temperature resistance, oil resistance, steam permeability and environmental stress cracking resistance. In addition, it has good electrical insulation and impact resistance and cold resistance, mainly used in blow molding, injection molding and other fields.

Linear low density polyethylene (LLDPE) is a copolymer of ethylene and a small amount of higher olefins in the presence of catalyst. LLDPE is similar to LDPE in appearance and poor in transparency, but it has good surface gloss, low temperature toughness, high modulus, flexural and stress cracking resistance, and better impact strength at low temperature.

The LLDPE application area has almost penetrated into all LDPE markets. At this stage, LLDPE and HDPE are in the growth stage of life cycle; LDPE is gradually entering the mature stage in the late 1980s, there are few LDPE equipment put into production in the world. Polyethylene can be molded by extrusion, injection, molding, blow molding and melt spinning. It is widely used in industry, agriculture, packaging and daily industry. Film is the largest user in China, consuming about 77% of low density polyethylene and 18% of high density polyethylene. Empty products occupy a large proportion in their consumption structure and play an important role in the plastic industry.

Chemical properties

Polyethylene has excellent chemical stability, resistance to hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, amines, sodium hydroxide, potassium hydroxide and other chemicals at room temperature corrosion, but nitric acid and sulfuric acid on polyethylene has a strong destructive effect.

Product use

High-pressure polyethylene: more than half used in film products, followed by pipes, injection molding products, wire coating, etc.

Medium and low pressure polyethylene: mainly injection molded products and hollow products.

Ultra-high pressure polyethylene (UHPPE): UHPE can be used as engineering plastics because of its excellent comprehensive properties.

Melting point 140 C

Melting enthalpy 292.88J/g

Printing

It is suitable for labeling of high performance products such as water, oil and chemicals. Hanyuan Printing often uses this material in cosmetics, shampoo, washing and other Daily Chemical labels with moisture and extrusion resistance requirements in the course of use. Excellent flexibility, especially for plastic bags. It can also be used for the use of PVC labelling materials for environmental protection requirements.

Processing

Polyethylene can be processed by blow molding, extrusion, injection molding and other methods, and is widely used in the manufacture of thin films, hollow products, fibers and household sundries.

Applied film

Low density polyethylene (LDPE) is widely used as packaging materials for various foods, clothing, medicine, fertilizers, industrial products and agricultural films. Composite film can also be processed by extrusion process for packaging heavy objects.

Since 1975, high density polyethylene (HDPE) film has also been developed. It has high strength, low temperature resistance, moisture resistance, and good printing and processability.

In addition, it can also be extruded on paper, aluminum foil or other plastic film coated with polyethylene to make polymer composites.

Hollow products

HDPE has high strength and is suitable for hollow products. Such as milk bottles and detergent bottles.

Tube sheet

The extrusion method can produce polyethylene pipe, high density polyethylene pipe strength, suitable for underground laying; extruded plate can be processed for secondary processing; also can be used foam extrusion and foam injection method to make high density polyethylene into low foam plastics, as bench board and building materials; protective sleeve (such as cable sheath).

fibre

China is called ethylene fiber, and generally uses low pressure polyethylene as raw material to spin synthetic fibers. Ethylene fiber is mainly used in the production of fishing nets and ropes, or spun into staple fibers used as flocs, but also can be used in industrial acid and alkali fabrics.

Ultra-high strength polyethylene fibers (strength up to 3-4GPa) have been developed, which can be used as composite materials for bullet-proof vest, automobile and marine operations.

Miscellaneous products

The sundries produced by injection molding include household sundries, artificial flowers, turnover boxes, small containers, bicycle and tractor parts, refrigerator containers, storage containers, household kitchen utensils, sealing caps, etc. High density polyethylene is used in the manufacture of structural parts.
