II. Superior Raw Materials
Our unwavering commitment to superiority is reflected in our choice of high-modulus polypropylene as the cornerstone for our underground drainage and wastewater solutions. With a remarkable elastic modulus of ≥1500 MPa, far exceeding HDPE's 800 MPa, it delivers exceptional ring stiffness and robust structural integrity, crucial for high-caliber applications.
Polypropylene is distinguished by its non-toxic, odorless nature and possesses a highly crystalline structure with an ultra-light density of 0.90-0.91 g/cm³. Its excellent water stability is demonstrated by an absorption rate of merely 0.01%. With molecular weights ranging from 80,000 to 150,000, polypropylene offers superior molding capabilities, providing an elegant and visually appealing finish, making it a prime choice for varied applications.
Polypropylene's remarkable chemical stability allows it to withstand a wide array of chemicals effortlessly; caution is advised only with concentrated sulfuric and nitric acids. While certain hydrocarbons may interact, its enhanced crystallinity bolsters its chemical resistance, making it ideal for creating durable, corrosion-resistant components for numerous applications.
As a non-toxic, odor-free material, polypropylene outperforms low-density polyethylene with its superior strength, rigidity, and heat resistance, operating efficiently around 100°C. Its outstanding dielectric properties and high-frequency insulation are unaffected by moisture, making it an adaptable choice for a wide array of industrial and commercial applications.
Boasting extraordinary resistance to common acids, bases, and organic solvents, polypropylene is ideally suited for food-grade utensil applications, where safety and durability are critical.
PPH, characterized by its high molecular weight and low melt flow homopolypropylene, is enhanced through β-modification, yielding a finely crystalline structure that significantly augments its chemical and temperature endurance, creep resistance, and impact resilience at low temperatures. This makes it an optimal choice for demanding environments.
