Product Description:

LLDPE , short for Linear Low-Density Polyethylene, is a type of polyethylene that is created by adding short branches onto HDPE. This unique composition merges the flexibility found in low-density polyethylene with the durability of high-density polyethylene. The key attributes of LLDPE are its high toughness, ease of processing, and resistance to low temperatures.

LLDPE is a versatile material that is widely used due to its exceptional properties. The incorporation of short branches distinguishes it from HDPE and grants it a remarkable combination of strength and flexibility. This makes LLDPE a preferred choice for various applications in industries such as packaging, construction, and transportation.

Features:

Physical Properties:

When it comes to physical properties, this material boasts an extremely strong toughness that is far superior to LDPE in terms of impact resistance and puncture resistance. For instance, it is ideal for making plastic bags for heavy objects that are not easily broken. In addition, it offers outstanding low temperature resistance, able to maintain good toughness even at -40 ℃ without easily becoming brittle. Despite having medium transparency, it does have slightly lower surface glossiness compared to LDPE.

Chemical Properties:

This material exhibits acid and alkali resistance, organic solvent resistance, and provides a good barrier against water and water vapor. It is known for its excellent electrical insulation properties and can serve as an insulation layer for wires and cables.

Processing Performance:

With regards to processing performance, this material offers good fluidity, making it easy to form through blow molding, extrusion, and other processes. It has a wide processing temperature range and high production stability, making it suitable for large-scale manufacturing of films, pipes, and other products.

Applications:

In the packaging field, polyethylene has the highest proportion and is commonly used for producing various types of films. These include stretch wrap film for packaging, food packaging film, agricultural film such as puncture-resistant greenhouse film, and heavy packaging film for fertilizers and feed.

In addition to its use in the packaging industry, polyethylene is also utilized in the manufacturing of pipes and profiles. It is used to create the inner layer of water supply pipes, gas pipes, and corrugated pipes due to its flexibility and sealing properties. Polyethylene is also used in the production of cable trays and other related applications.

Polyethylene finds additional applications in various fields such as the production of wire and cable insulation layers, plastic toys, container covers, and disposable items like gloves and aprons. Its versatility and durability make it a popular choice in a wide range of industries for different products and applications.
