Polyethylene Compound for the Production of PEX, PE-RT Pipes and XLPE Cables

Polyethylene Compound is one of the most widely used engineering compounds in the pipe and cable industry, which is produced by adding various stabilizers, masterbatches and special additives to the base polyethylene. This compound improves the physical, thermal and process properties of polyethylene according to the intended application. Polyethylene compound has a special place in the production industries of PEX, PE-RT pipes and XLPE cables and guarantees features such as resistance to temperature, pressure and cracking in the final product. At Behin Polymer, we produce a variety of specialized and high-quality compounds and provide them to various industries at the best price.

Polyethylene Compound and Its Types

Polyethylene compound is a specialized combination of base polymer and functional additives. Depending on the type of application, these products include antioxidants, UV stabilizers, anti-cracking agents, and color masterbatches. The formulation structure of these compounds is adjusted in such a way that they provide stable and reliable performance against harsh environmental conditions, mechanical and temperature stresses. Below, we will review some of the types of polymer products of Behin Polymer Company.

PEX Compound

PEX polyethylene compound is for PEX pipes that improves the thermal and mechanical properties of the pipe by creating cross-links in the polyethylene polymer chains (Cross-linking). This process is carried out by adding a curing agent (Crosslinking Agent) during or after the extrusion stage. PEX pipe compound with the ability to be cross-linked offers high resistance to high temperatures, internal pressure and environmental stresses and is an ideal option for underfloor heating systems, hot water piping and sanitary industries.

PEX polyethylene compound has excellent thermal and dimensional stability due to its network structure. These compounds are resistant to impact, stress cracking, and chemical effects, and have a low coefficient of linear expansion. The use of these materials in residential plumbing, industrial installations, and hot and cold water transmission is increasing day by day due to their durability and long service life.
Some of the advantages of these products are:
• Excellent heat resistance and high pressure resistance
• High chemical resistance to acids and alkalis
• Low thermal expansion coefficient
• Dimensional stability

PE-RT compound

PE-RT polyethylene compound for PE-RT pipes (Polyethylene raised temperature) is a flexible compound with a controlled molecular structure and high temperature resistance that is produced without a cross-linking process. This compound maximizes temperature resistance, flexibility and weldability in piping systems by using special branched polyethylene and anti-oxidation and anti-UV additives. PE-RT polyethylene compound is an optimal choice for drinking water transmission, underfloor heating and cooling systems, and medical and food applications. On the other hand, due to its special molecular structure, this product can withstand continuous temperatures up to 70 degrees Celsius without losing mechanical properties.
Some of the advantages of these products include:
• Excellent resistance to environmental stress ESCR
• Easy weldability with conventional methods
• No crosslinking process and easy production
• Approved for contact with drinking water

XLPE Compound

The XLPE polyethylene compound for XLPE cables is made from a combination of polyethylene and antioxidant, anti-oxidation, UV stabilizer and crosslinking agent additives. This compound creates a network structure in the polymer during the extrusion process and under radiation or heat. XLPE compound is widely used in the electrical industry and power plants due to its excellent insulation properties at medium and high voltages.

XLPE polyethylene compound provides stable performance by maintaining its insulating properties at high temperatures up to 90°C in continuous operation and 250°C in short circuit conditions. This compound is resistant to moisture absorption, thermal degradation and cracking and has high mechanical strength.
Some other advantages of XLPE cable compound include:
• Highly stable electrical insulation
• Excellent resistance to moisture and oxidation
• Optimal mechanical strength
• Reduced water absorption and increased cable life
• Suitable for medium and high voltages

Polyethylene compound purchasing tips

When purchasing polyethylene compounds, it is of great importance to accurately understand the type of application and the required technical specifications. Examining thermal properties, environmental stress resistance (ESCR), operating temperature, process method, and insulation requirements are among the main points that should be considered before selecting a product. Also, health standards and valid quality approvals in the selection of suppliers play a decisive role in maintaining the safety and performance of pipe and cable products.

Factors affecting the price of polyethylene compounds

The price of polyethylene compounds is affected by factors such as the type of grade of raw materials, additives used, order volume and production technology. At Behin Polymer, we use up-to-date machinery, mass production, direct supply of raw materials from
