Polybutene-1 | Major Projects

Polybutene-1 piping systems have become a vital component part of modern building technology. Offering a best in class ecology profile, they assist the goal of sustainable building. PB-1 thermally outperforms alternative systems made from traditional plumbing and heating materials and is increasingly selected by specifiers for major projects because of its long life, low maintenance, logistics, ease of on-site handling and cost benefits.

Polybutene-1 compared to PE-RT & PEX

A Polybutene underfloor piping system was chosen to heat the Canary Wharf Wintergarden complex.

Universal System

In today's building technology, plastic piping systems are being used extensively in large projects. The advantages of plastic far outweigh those of metal, especially in complex applications. Complete piping systems are generally installed using pipes with diameters from 10 mm to 225 mm. Both pipes and fittings can be produced from Polybutene-1 for universal piping systems.

PB-1 advantages for major project installations

  • Safe and reliable jointing technologies
  • Flexibility in planning and implementation
  • Physical and chemical material properties
    (no corrosion and buildup)
  • Hygienic and non-toxic (for drinking water)
  • Lightweight and manageable on-site
  • Flexible installation, allows bending around obstructions
  • Long lengths require less connections
  • No flame or chemicals required
  • One material from entry point to last tapping point

Systems Applications

Project Categories

With working pressures of up to 16 bar and working temperatures of up to 95°C, PB-1 piping systems deliver significant benefits for major installations.

PB-1 systems are specified for facilities such as:

  • Hospitals, homes for the elderly
  • Schools
  • Sewage plants
  • Sports facilities (football stadiums, gymnasiums)
  • Shopping centres
  • Office buildings
  • Hotels and apartments
  • Thermal baths, health resorts
  • Airports, train stations
  • District heating systems


Polybutene is often referred to as Polybutene-1, Polybutylene, PB-1 or PB.

Polybutene is not sold by PBPSA members for use in pipe applications intended for use in North America, and those parties require their customers or distributors not to sell products made from Polybutene into pipe applications for North America.
