In the fields of building water supply and drainage and HVAC systems, the evolution of piping materials has always been driven by the pursuit of higher performance, longer service life, and greater safety margins. While traditional PP-R (random copolymer polypropylene) has become a market mainstream, a superior-performing material—PP-RCT (Polypropylene Random Crystallinity Temperature resistant)—is establishing itself as the new benchmark for high-standard engineering, grounded in solid materials science.
