II. Superior Raw Materials
Our steadfast dedication to quality shines through our selection of high-modulus polypropylene as the cornerstone for our underground drainage and wastewater solutions. With an impressive elastic modulus of ≥1500 MPa-significantly exceeding HDPE's 800 MPa-this material ensures exceptional ring stiffness and robust structural integrity, crucial for high-performance applications.
Polypropylene stands out as a non-toxic, odorless material with a highly crystalline structure and ultra-light density of 0.90-0.91 g/cm³. Its extraordinary water stability is proven by a mere 0.01% absorption rate. Moreover, 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 numerous applications.
Polypropylene's chemical stability is exceptionally noteworthy, allowing it to resist various chemicals, with caution needed only with concentrated sulfuric and nitric acids. While interactions with some hydrocarbons may occur, its superior crystallinity enhances its chemical resistance, rendering it an ideal choice for crafting durable, corrosion-resistant components across numerous applications.
As a non-toxic and odor-free material, polypropylene surpasses low-density polyethylene with its superior strength, stiffness, and heat resistance, performing exceptionally well near 100°C. Its excellent dielectric properties and high-frequency insulation remain unaffected by moisture, making it versatile for a wide range of industrial and commercial applications.
Showcasing exceptional resistance to common acids, bases, and organic solvents, polypropylene is perfectly suited for food-grade utensil applications where safety and durability are paramount.
PPH, known for its high molecular weight and low melt flow homopolypropylene, is enhanced by β-modification, resulting in a finely crystalline structure that elevates its chemical and temperature endurance, creep resistance, and impact resilience at low temperatures. This makes it an ideal choice for the most demanding environments.
