PEX Compound

PEX compound is a cross-linked polyethylene compound and has gained a special place these days as one of the advanced and widely used raw materials in the pipe and fittings industries. Using this polyethylene compound simultaneously increases the quality of products and reduces costs. At Behin Polymer, we produce the best and highest quality types of PEX compounds and provide them to industries at the best prices.

PEX pipe compound

PEX compound is produced by combining polyethylene and specific chemical processes and will ultimately lead to the creation of a network structure in the polymer. This network structure gives specific mechanical and chemical properties to the PEX material. In fact, ordinary polyethylene is converted into PEX compound during the crosslinking process and this process can be carried out through various methods such as peroxide, silane or irradiation. This type of polyethylene compound is prepared by the silane method at Behin Polymer Company. In fact, it is PEX-b.

On the other hand, this material has many features, such as significant chemical stability, due to its structure. This has led to the use of PEX compound in many industries, especially plumbing. One of the reasons for the popularity of PEX compound in various industries is the optimal combination that this material provides between flexibility, high durability and corrosion resistance. This has led contractors and engineers to use this material in their large and sensitive projects.

What are the features of PEX compound?

PEX compound has several features, each of which can attract the attention of engineers, especially in the pipe and fittings industries. The numerous features that this material possesses have greatly increased the use of various types of PEX compounds. We will examine some of these features below.

1- High temperature resistance

Due to its network structure, PEX compound has high heat resistance and does not deform or degrade at high temperatures. This property allows it to perform stably in conditions such as hot water piping, underfloor heating or high temperature industrial systems. Many conventional polymers become soft or brittle at high temperatures, but PEX maintains its mechanical properties.

The working temperature of this material usually reaches 90 degrees and the instantaneous temperature reaches 110 degrees Celsius, and its long-term tolerance to high temperatures increases the useful life of the product. This feature will also reduce the need for system replacement or repair in the long term. Therefore, PEX compound is a safe choice in construction and industrial projects.

2- Better resistance to chemicals and chlorine

PEX compound is highly resistant to many chemicals, including chlorine found in municipal water. This feature prevents the polymer structure from degrading during prolonged contact with corrosive materials. The presence of crosslinks provides greater stability against chemical reactions. In drinking water or industrial piping systems, this resistance will increase the useful life of the equipment. Finally, PEX compound also reduces the risk of leaks or cracks due to chemical erosion.

3- Improve oxidation resistance

Oxidation is one of the main factors in the degradation of polymers in the presence of air and oxidizing agents. The reinforced polyethylene compound PEX shows good resistance to this process. Special additives in its composition prevent the polymer chains from breaking down over time. This high resistance will maintain mechanical and physical properties throughout the product’s life. As a result, pipes and parts made from it do not suffer from premature deterioration.

4- Better abrasion resistance

PEX compound is highly resistant to mechanical abrasion caused by fluid flow, suspended particles, or repeated contact. This feature prevents wall thickness reduction and surface cracks. In pipelines where there is high pressure and flow, PEX compound is more durable than conventional polymers. With this resistance, the possibility of leakage or breakage due to friction is reduced.

5- Excellent strength at high temperatures

In addition to its heat tolerance, PEX compound maintains good mechanical strength at high temperatures. This advantage prevents pipes from bending or cracking when temperatures rise. Its structural stability under pressure and heat is one of its key features. It does not lose its shape and function in environments with severe temperature fluctuations. This high strength reduces the need for replacement or repair in the long term.

6- Resistance to slow crack growth

One of the important advantages of PEX compound is its resistance to slow crack growth over time. This property prevents the propagation of microcracks that can lead to complete failure. Its network structure and uniformity prevent the penetration and propagation of internal stresses. Such a property is of great importance in long-term applications or those exposed to repeated loads. This increases the safety and stability of pipes in sensitive systems.

7- Improving electrical properties

PEX compound exhibits good electrical insulation properties due to its stable structural composition. This feature makes it suitable for use in the coating of low and medium voltage cables. High resistance to current leakage and electrical discharge increases system safety, and its suitable dielectric properties prevent damage to electronic equipment. Therefore, PEX pipe compound also has a special place in the electrical industry.

Applications of PEX compound in various industries

PEX compound is used in many industries due to its unique properties. Among the industries that directly benefit from this type of polymer material are construction facilities, automotive manufacturing, etc. In fact, this compound is a reliable and durable choice for environments with harsh conditions or high temperature changes due to its diverse features.

The main applications of PEX compound are as follows:

• Single-layer and multi-layer pipes used in hot and cold water piping systems
• Underfloor heating system
• Gas transmission system
