II. Superior Raw Materials
Our unwavering commitment to quality is exemplified by our choice of high-modulus polypropylene as the foundational element for our underground drainage and wastewater solutions. With an impressive elastic modulus of ≥1500 MPa-remarkably surpassing HDPE's 800 MPa-it guarantees extraordinary ring stiffness and robust structural integrity, essential for high-performance applications.
Polypropylene distinguishes itself as a non-toxic, odorless material with a highly crystalline structure and ultra-light density of 0.90-0.91 g/cm³. Its outstanding water stability is demonstrated by a mere 0.01% absorption rate. Furthermore, with molecular weights ranging from 80,000 to 150,000, polypropylene excels in molding capabilities and presents an elegant, attractive finish, making it the ideal choice for a plethora of applications.
Polypropylene's chemical stability is truly remarkable, allowing it to withstand various chemicals; caution is only necessary with concentrated sulfuric and nitric acids. While it may interact with some hydrocarbons, its enhanced crystallinity elevates its chemical resistance, making it an ideal choice for crafting durable, corrosion-resistant components across numerous applications.
As a non-toxic and odor-free material, polypropylene outperforms low-density polyethylene with superior strength, stiffness, and heat resistance, functioning exceptionally well near 100°C. Its excellent dielectric properties and high-frequency insulation remain unaffected by moisture, making it versatile for an extensive array 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 crucial.
PPH, characterized by its high molecular weight and low melt flow homopolypropylene, is enhanced by β-modification, yielding a finely crystalline structure that boosts its chemical and temperature endurance, creep resistance, and impact resilience at low temperatures. This makes it an ideal choice for demanding environments.
