Hyosung PP RCT performance material of choice for pipe

High-temperature resistant β-crystalline polypropylene, PP-RCT (Poly Propylene Random Crystallinity Temperature), is an improved new generation of polypropylene material. The following is a detailed introduction to PP-RCT:

What is PP-RCT? What are the characteristics of PP-RCT?

PP-RCT is the abbreviation of Poly Propylene Random Crystallinity Temperature, also known as high-temperature resistant β-crystalline polypropylene.

Characteristics: PP-RCT uses a hexagonal crystal form instead of the monoclinic form of PP-R. This change in molecular structure gives it higher heat resistance, pressure resistance and toughness.

Performance advantages of PP-RCT

(1) Heat resistance: The melting range (melting temperature range) of PP-RCT is usually higher than that of PP-R, indicating that it requires a higher temperature to melt and thus has better resistance to high temperature deformation. According to industry standard testing, PP-RCT can be used for 50 years at a temperature of 90°C and a pressure of 1.0MPa, which is 20°C higher than the operating temperature of PP-R.

(2) Pressure resistance: Compared with PP-R, the long-term strength of PP-RCT at high temperatures is increased by more than 50%, which allows the pipe wall to be made thinner while maintaining or improving the pressure-bearing capacity.

(3) Toughness: The notched impact strength of PP-RCT has been greatly improved compared to PP-R, indicating that its low-temperature brittleness has been greatly improved and it has better impact resistance.

(4) Creep resistance: PP-RCT has a long creep resistance time, and the long-term hydrostatic test curve has no inflection point, indicating that it can maintain stable performance during long-term use.

(5) Anti-oxidation and anti-crack growth: PP-RCT has better anti-oxidation ability and resistance to slow crack growth, which helps extend the service life of the pipeline.

PP-RCT application fields

Because PP-RCT has the above-mentioned excellent properties, it is widely used in situations that require high temperature, high pressure and good toughness, such as high-temperature heating facilities, hot water supply systems, and corrosive chemical industry piping systems.

PP-RCT Market and Manufacturers

Borealis is the first company to launch PP-RCT on the market, and its PP-RCT materials have high visibility and recognition in the market. In addition, companies such as German Aqua-SCIE, as global strategic partners of Borealis, are also actively promoting and applying PP-RCT materials to produce high-end pipeline systems with outstanding advantages in hot and cold water supply and heating.

In summary, high-temperature resistant β-crystalline polypropylene (PP-RCT) is a new type of polypropylene material with excellent properties and has broad application prospects and market potential.
