- High densityThe density of HDPE is usually 0.94g/cm ³ Compared to other types of polyethylene, the density is higher.
- Excellent physical performanceHDPE has high strength, stiffness, and hardness, as well as good heat and cold resistance.
- Good chemical stabilityHDPE has good corrosion resistance to most acids, alkalis, and organic solvents.
- Excellent electrical insulation performanceHDPE has good electrical insulation performance and is suitable for electrical applications such as wire and cable insulation layers.
Packing materialDue to its excellent flexibility and chemical resistance, low-pressure high-density polyethylene is often used in the production of packaging materials such as plastic bags, plastic films, and packaging films.
Plastic containersPlastic containers made of low-pressure high-density polyethylene have good impact and chemical resistance, and are often used to make food containers, cosmetic bottles, pharmaceutical bottles, etc.
Agricultural sectorThe flexibility and weather resistance of low-pressure high-density polyethylene make it an ideal material in the agricultural field, often used to make agricultural films, greenhouse films, agricultural water pipes, etc.
Medical devicesLow pressure high-density polyethylene has good biocompatibility and chemical resistance, and is often used in the production of medical devices, medical packaging materials, etc.
Industrial pipelinesThe corrosion resistance and pressure resistance of low-pressure high-density polyethylene make it an ideal material for industrial pipelines, often used in the transportation of chemicals, water treatment and other fields.
1. Differences from LDPE:
(1) Density and hardness: HDPE has a higher density than LDPE, which makes HDPE products harder and more sturdy.
(2) Transparency: LDPE has good transparency, while HDPE appears semi transparent or opaque.
(3) Heat resistance: HDPE has better heat resistance than LDPE and can withstand higher temperatures without deformation.
(4) Usage: Due to its high hardness and heat resistance, HDPE is often used to manufacture products that require high strength, such as buckets, water pipes, cable sheaths, etc. LDPE, on the other hand, is often used to manufacture daily necessities such as films, packaging bags, and containers.
2. Differences from LLDPE:
(1) Density and flexibility: LLDPE has a density between HDPE and LDPE, but has better flexibility.
(2) Strength and stiffness: Although LLDPE has slightly lower strength and stiffness than HDPE, its toughness makes it more advantageous in certain applications.
(3) Transparency and Gloss: LLDPE has a higher transparency and a certain surface gloss.
(4) Usage: Due to its excellent flexibility and transparency, LLDPE is often used in the manufacturing of stretch films, wrapping films, plastic bags and other products. HDPE is more suitable for applications that require high strength and heat resistance.
