II. Superior Raw Materials
Our relentless pursuit of excellence is embodied in our choice of high-modulus polypropylene as the foundation of our underground drainage and wastewater solutions. With an impressive elastic modulus of ≥1500 MPa-surpassing HDPE's 800 MPa-it ensures remarkable ring stiffness and robust structural integrity, essential for high-performance applications.
Polypropylene, celebrated for its non-toxic, odorless qualities, boasts a highly crystalline structure and ultra-light density of 0.90-0.91 g/cm³. Its excellent water stability is demonstrated by a mere 0.01% water absorption rate. Moreover, with molecular weights ranging from 80,000 to 150,000, polypropylene excels in molding capabilities, offering a refined, attractive finish suitable for diverse applications.
Polypropylene's remarkable chemical stability enables it to withstand a wide range of chemicals; caution is advised only with concentrated sulfuric and nitric acids. Although it might interact with certain hydrocarbons, its enhanced crystallinity augments its chemical resistance, making it ideal for creating durable, corrosion-resistant components across numerous applications.
As a material free from toxins and odors, polypropylene surpasses low-density polyethylene with superior strength, stiffness, and heat resistance, performing remarkably near 100°C. Its excellent dielectric properties and high-frequency insulation remain unaffected by moisture, making it versatile for a broad spectrum of industrial and commercial applications.
Demonstrating exceptional resistance to common acids, bases, and organic solvents, polypropylene is perfectly suited for food-grade utensil applications where safety and durability are of utmost importance.
PPH, characterized by its high molecular weight and low melt flow homopolypropylene, is enhanced through β-modification, resulting in a finely crystalline structure that enhances its chemical and temperature endurance, creep resistance, and impact resilience at low temperatures, making it ideal for challenging environments.
