What is Polyethylene Compound (PE)?

Polyethylene compound is a thermoplastic material made by combining base polymer materials with additives such as calcium carbonate and talc, antioxidant additives, lubricants, and color pigments. Polyethylene is one of the most widely used compounds in the plastic industry and encompasses a wide range of products. PE compound can act as an insulator against moisture and enhance the resistance and strength of the product. Moreover, due to its economical price, production costs are reduced. This material comes in various grades, which will be discussed further below.

Features of PE Compound 

High physical resistance: This material has strong and dense interconnected chains, which increases the physical resistance and stability of the product when added.

Facilitation of production processes: This material has good processability, meaning it deforms well during various production stages such as molding and is receptive to alteration.

Thermal resistance: This substance is highly resistant to high temperatures and is immune to temperature variations.

Insulation: Polyethylene is an excellent insulator in most areas, including heat and electricity, and is therefore used in the manufacture of electrical cable insulation and enclosure insulation.

Cost savings: This compound contains multi-functional properties due to its additive components, which means that the manufacturer does not need to use additional raw materials.

Types of Polyethylene Compound (PE)

High-Density Polyethylene (HDPE): This grade has good physical resistance and strength, making it resistant to impact and tensile stress. It is widely used in industries such as textiles, fibers, product packaging, etc.

Low-Density Polyethylene (LDPE): The low-density grade has lower physical strength compared to the previous one. This material is used in the production of bottles, garbage bags, and various types of packaging.

Ultra-High-Molecular-Weight Polyethylene (UHMWPE): This material is the heaviest grade among all compounds. To grasp its weight, it is important to know that its molecular weight is one million grams per mole! This material is used in the production of heavy industrial parts such as rollers and bearings.

Applications of PE Compounds

Insulation: Insulation from this compound is used to produce coverings for electrical cables to prevent electrical theft and connections, as well as to maintain or prevent the entry of heat.

Automotive Industry: The application of this compound in the automotive industry is in the production of strong components that are resistant to severe physical impacts and high temperatures.

Agricultural Industry: This material is used in the production of drip tapes and irrigation pipes, which require a substance that does not decay over a relatively long period and does not cause pollution.

Pipes and Fittings: Water and gas pipes are vulnerable in various conditions; therefore, this compound is used. This material prevents premature degradation of pipes against moisture, pressure, and high temperatures.
