Product Features & Advantages

Exceptional Long-Term Hydrostatic Strength. RA150E delivers superior long-term hydrostatic pressure resistance, making it highly suitable for hot and cold water supply systems that operate under sustained high temperatures and pressures. The resin complies fully with international standards such as ISO 15874 and GB/T 18742, ensuring dependable performance and service life that extends across several decades.
Excellent Mechanical Properties. This material offers a balanced combination of high tensile strength and flexural modulus, giving pipes and fittings strong resistance to cracking, deformation, and creep. It also provides stable dimensional behavior during pipe extrusion and injection molding processes. Even under varying temperature or pressure conditions, RA150E retains mechanical integrity and structural reliability.
Strong Impact Resistance at Various Temperatures. PP Borouge RA150E demonstrates excellent notched impact strength at room temperature (23°C) and maintains good toughness even at 0°C. This low-temperature impact resistance minimizes the risk of brittle failure during winter installation or use in colder climates.
Superior Processing Stability with Borstar® BNT Technology. With the support of Borstar® BNT nucleation technology, the resin exhibits faster crystallization and reduced cooling time, enabling higher processing efficiency. Its refined and uniform molecular structure provides consistent shrinkage and excellent pigment dispersion when using masterbatch. These advantages contribute to smooth and stable pipe extrusion, precise dimensions, and improved production output.
Hygienic, Odor-Free, and Corrosion Resistant Performance. RA150E is chemically resistant to acids, bases, salts, and typical industrial fluids. Being non-toxic and odorless, it is fully suitable for potable water applications. The material does not scale, rust, or corrode, offering a cleaner and safer alternative to metal pipes. Its lightweight structure also facilitates easy handling, installation, and heat-fusion joining.
Excellent Weldability for Reliable Jointing. The resin provides outstanding melt-bonding behavior, ensuring strong, durable, and leak-free connections in PP-R piping systems. Borouge RA150E is compatible with standard PP-R fittings, helping manufacturers and installers achieve uniform performance across complete pipeline systems.

Recommended Applications of Borouge RA150E PPR

Residential and Commercial Buildings. RA150E is extensively used in the manufacture of PP-R pipes and fittings for modern residential and commercial water supply systems. It is ideal for hot and cold potable water pipelines, bathroom and kitchen plumbing installations, as well as circulating hot-water distribution networks that require long-term thermal and pressure stability.
Heating Systems. The resin performs exceptionally well in heating applications, including underfloor heating pipelines, radiator and central heating connections, and continuous hot-water delivery loops. Its strong thermal resistance and durable mechanical performance ensure reliable operation in demanding heating environments.
Industrial and Technical Applications. In industrial sectors, RA150E supports a wide range of fluid transport requirements. It is suitable for process water lines, compressed air systems, and chemical liquid handling within the compatibility limits of PP-R material. The resin’s corrosion resistance, structural stability, and hygienic nature make it a reliable choice for technical and industrial pipeline configurations.
