It is a thermoplastic polymer made from petroleum. It comes in white powder or granular form. Its hardness, tensile strength and creep properties are better than those of low density polyethylene. Good wear resistance, electrical insulation, toughness and cold resistance; Good chemical stability, at room temperature, insoluble in any organic solvent, acid, alkali and various salts corrosion resistance.
1. Easy to smelt and cast
One of the main advantages of this plastic material is its malleability, which makes it easy to shape and transform into any shape or design. Due to its high melting point, once it is reached, this HDPE material can be molded quickly and efficiently for a variety of unique applications, from cutting boards, detergent bottles, baby bottles, and food containers to pipes, plastic trays, and more.
2. Lightweight
The density range of HDPE is 0.93 ~ 0.97g/cm3, and the strength density ratio is large. HDPE has fewer linear branches, stronger intermolecular forces, and even higher tensile strength than LDPE.
3. Corrosion resistance
HDPE has the characteristics of anti-mold, anti-insect, anti-corrosion, and durable, weather resistant, can be disinfected by boiling, is the ideal material for making food and beverage containers. In addition, HDPE can withstand most strong mineral acids and bases and has good resistance to natural chemicals. In addition, this material is virtually impervious to most common chemicals, water, solvents, acids, detergents and can withstand some of the harshest weather.
4. Long life
Due to its strong impact resistance, chemical resistance and weather resistance, HDPE can be more durable than traditional materials and continue to be used after recycling.
5. Sustainability
HDPE is easy to recycle, which helps remove non-biodegradable waste from landfills and helps reduce plastic production by up to 50%. This is why many recycled plastic products, such as recycled plastic pallets and industrial bins, contain HDPE.
3. Application
1. Injection molded products: turnover boxes, bottle caps, buckets, caps, food containers, plates, garbage bins, boxes, and plastic flowers
2. Blow molding products: hollow molding products, such as various series of blow molding barrels, containers, bottles, holding detergent, chemicals, cosmetics, gasoline tanks, daily necessities, etc. There are blown film products such as food packaging bags, grocery bags, fertilizer lined film and so on.
3. Extruded products: pipes and fittings are mainly used in gas transportation, public water and chemical transportation, such as building materials drainage pipes, gas pipes, hot water pipes, etc. sheets are mainly used in seats, suitcases, handling containers, etc.
4. Rotary molding: injection molded products such as large containers, storage tanks, barrels, boxes, etc.
5. Polyethylene can be processed into film, wire and cable sheath, pipe, all kinds of hollow products, injection products, fibers and so on.
6, other uses: HDPE can also be used to manufacture home appliance shell, sports equipment, vehicle parts, garbage cans, sinks and so on.
4. Factors that affect the price
1. Price of raw materials
The production of HDPE requires the use of raw materials such as ethylene, and the price fluctuations of these raw materials will directly affect the production cost of HDPE. In general, the fluctuation of crude oil prices has the most direct and significant impact on the price of HDPE materials. Higher crude oil prices will lead to higher prices of raw materials such as ethylene, which will push up the price of HDPE materials.
2. Market supply and demand relationship
When market demand is greater than supply, HDPE material prices tend to rise; On the contrary, when the market supply is greater than the demand, the price of HDPE materials will decline. Therefore, the fluctuations in the price of HDPE materials are closely related to market supply and demand.
3. The impact of policies and regulations will also have a certain impact on the price of HDPE materials.
4. Adjustment of government policies and regulations on environmental protection and resource utilization,
It will lead to an increase in the production cost of HDPE manufacturers, which will push up the price of HDPE materials.
5. The impact of international market
Changes in the international market will have a certain impact on the domestic HDPE market, fluctuations in international crude oil prices, international trade policy adjustments, etc., may have a certain impact on the price of HDPE materials.
