Product Description

Product Introduction

HDPE, or High - Density Polyethylene, stands as a cornerstone in the plastics realm. Derived from ethylene monomer polymerization, it's a thermoplastic celebrated for its robustness. Boasting a density range of 0.941-0.965 g/cm³, it outshines LDPE in rigidity and tensile strength. Resistant to chemicals, temperatures (melting at 120-130°C), and wear, yet adaptable via additives for weathering needs. Its molecular structure, a tightly packed carbon - chain backbone, grants stability-making it indispensable across industries, from packaging to infrastructure, where durability and reliability are paramount.

Product Application

1. Packaging Industry

 

• Plastic Containers: HDPE is commonly used to manufacture containers for various products. For instance, it is the material of choice for making bottles of household cleaning products like detergents and bleach, as well as personal care items such as shampoo and conditioner bottles. Its chemical resistance protects the contents from reacting with the container, and its strength ensures the container can withstand handling and transportation. In the food industry, HDPE is used for packaging edible oils, milk, and sauces. Special grades of food - grade HDPE meet strict safety standards to prevent any contamination of the food products.
• Plastic Films and Bags: HDPE films are used for packaging applications that require strength and durability. These films are often used in industrial packaging to protect goods from moisture and physical damage. HDPE is also used to make shopping bags, garbage bags, and agricultural packaging such as silage bags, which are used to store and preserve animal feed.

 

1. Construction and Pipe Systems

 

• Water Supply and Drainage Pipes: HDPE pipes are extensively used in municipal water supply and drainage systems. Their corrosion resistance eliminates the need for costly anti - corrosion treatments, and their smooth inner surface reduces friction, allowing for efficient water flow. HDPE pipes are also lightweight, making them easier to transport and install compared to traditional metal or concrete pipes. They have a long service life, often exceeding 50 years, and can withstand ground movement without cracking.
• Building Materials: In construction, HDPE can be used to make various components such as geomembranes for landfill liners to prevent the leakage of waste and contaminants. It is also used in the production of insulation materials, roofing membranes, and some types of decorative panels due to its weather resistance and durability.

 

1. Industrial Applications

 

• Chemical Tanks: HDPE's excellent chemical resistance makes it an ideal material for manufacturing storage tanks for chemicals, both in industrial settings and laboratories. These tanks can safely store acids, alkalis, and other corrosive substances without the risk of degradation or leakage.
• Mechanical Parts: HDPE can be injection - molded into various mechanical parts, such as gears, bearings, and rollers, especially in applications where low friction, wear resistance, and chemical resistance are required. It is also used in the production of automotive components like fuel tanks and battery cases due to its lightweight and safety features.

 

1. Agriculture

 

• Irrigation Systems: HDPE pipes are commonly used in agricultural irrigation systems. They are resistant to the chemicals and fertilizers used in farming, and their flexibility allows for easy installation in different terrains. Drip irrigation systems often use HDPE pipes to efficiently deliver water and nutrients to crops.
• Greenhouse Films and Covers: Some greenhouse films and covers are made from HDPE or HDPE - based composites. These materials provide good light transmission, thermal insulation, and durability, creating a suitable environment for plant growth.
