Cross-Linkable Compounds for Plumbing 

Polidan® PEX

Monolayer and multilayer PEX pipes made from Polidan® compounds are flexible and have excellent strength from below freezing up to 95°C. PEX piping systems are quieter than rigid metal piping systems and require fewer fittings, making them easier and less costly to install.

Over the past 30 years, this unique combination of properties has allowed Polidan® PEX to successfully replace metal in piping materials used in pressurized hot water plumbing systems, service lines and hydronic radiant heating systems.

Polidan® PEX compounds are globally approved for use with hot potable water and are certified by KTW, NSF and WRc.

Outperforms Thermoplastic Polyolefins

• Improved resistance to oxidative aging
• Higher strength at elevated temperature
• Better chemical and chlorine resistance
• Higher heat resistance
• Improved low-temperature impact strength
• Superior resistance to crack propagation
• Better abrasion resistance

Polidan® PEX is a family of silane cross-linkable polyethylene compounds. This means that permanent connections, known as cross-links, are chemically formed between molecular chains to create a three-dimensional structure. As a result, crosslinked polyethylene (PEX) has better thermal stability, mechanical properties and resistance to chemical attack than thermoplastic polyolefins.

Polidan® PEX for Pipes & Fittings

These cross-linkable compounds can be used for the production of different pipes and fittings where higher temperature, pressure, abrasion and chemical resistance are required within the underground sector. Special grade available for highly flexible pipes.

PEX pipes made from Polidan® compounds perform at a significantly higher level than the standards specified in ISO 15875 for PEX pipe used in hot and cold water piping systems.

Polidan® TUX 100 is a specialty designed crosslinkable PEX-b compound that allows pipes and fittings to be thermally welded similar to PE pipe and cross-linked in situ, to achieve higher characteristics than standard PEX materials.

Polidan® PEX for Gas Systems

In-house gas transport using plastic pipes is increasingly supported worldwide by international standards. Pipes made using Polidan® compounds can be certified to distribute gas, offering:

• Very low permeability to combustible gas and to its smelling components
• Superior mechanical resistance, allowing use for indoor gas pipes
• Excellent processing stability for high-precision pipe tolerances
