Understanding HDPE Plastic Granules – Applications in Life

Understanding HDPE Plastic Granules

What is HDPE plastic granules?

HDPE is the abbreviation for Hight Density Poli Etilen, widely used in daily life. This is also the material used to produce plastic bags and many other plastic utensils.

HDPE is the result of polymerization of ethylene molecules with high density at low pressure and in addition combined with catalysts such as chromium or silicon catalyst… In addition, during the production process, gas molecules will form under polymer form and form solid polyethylene, then molded to form granules.

Thermophysical properties of HDPE

Plastic beads have the following thermophysical properties:

Density: 940 kg/m3
Melting temperature: 130.8 degrees Celsius
Crystallization temperature: 111.9 degrees Celsius
Heat capacity: 178.6 kJ/kg
Thermal conductivity: 0.44 W/m
Specific heat: Approx. 1330 – 2400 J/kg-K
Crystallization: 60%

Some outstanding features of HDPE plastic granules

HDPE is a durable plastic that resists natural corrosion extremely well such as water, wind, rain, dirt, etc. HDPE plastic material is also resistant to direct sunlight.

Outstanding strength and heat resistance compared to other plastic materials, HDPE pipes, even at -40 degrees Celsius, do not change pressure, fire resistance is 2 times better than conventional materials. often.

The granules have good chemical resistance, no side effects on contact and are 100% recyclable.

Products from HDPE are cheaper than those made from other materials. Plastic is also light in weight, so it is durable, easier for users to assemble or maintain.

Application of HDPE granules

In the industry, HDPE is used as a drainage pipe, especially in areas with complex terrain, the use of plastic pipes becomes even more convenient due to its light weight, flexibility, and ease of installation and construction. becomes easier. In particular, if used and constructed correctly, plastic pipes have a very long life expectancy of up to 50 years. Therefore, it is often used as a large-scale waste pipe for industrial or urban areas.

In addition, HDPE plastic is also widely used in daily life such as:

• Making household tools: cutting boards, shelves, floor mats, plastic cabinets, …
• Making water pipes in the agricultural industry system.
• Raw materials for making plastic bottles, plastic boxes and can be recycled, so the product is very popular.
• Making toys: Plastic is non-toxic and resistant to harmful effects from ultraviolet rays, so it is very safe to use as a toy for children.
• Used to manufacture chemical tanks and tanks for the safety industry: Common storage tanks such as washing powder, conditioner, cleaning products,….
