Main Applications of PP T4401

  • Hot and Cold Water Pipes. PP T4401 is widely used to manufacture PP-R pipes for residential, commercial, and municipal water supply systems where durability and long-term reliability are essential.
  • Underfloor Heating Systems. Its excellent thermal endurance makes it suitable for radiant floor heating pipes that operate continuously under elevated temperatures.
  • PP-R Pipe Fittings. The resin is ideal for producing injection-molded fittings such as elbows, tees, couplings, reducers, and unions, ensuring compatibility with PP-R piping systems.
  • Building Plumbing Systems. PP T4401 serves a broad range of plumbing applications in apartments, hospitals, hotels, schools, office buildings, and other infrastructure projects.
  • Industrial Fluid Transport. The material is also suitable for conveying cooling water, process water, and selected chemical solutions that require corrosion-resistant piping.
