II. Superior Raw Materials
Our unwavering commitment to quality is reflected in our choice of high-modulus polypropylene, the foundation of our underground drainage and wastewater solutions. With an exceptional elastic modulus of ≥1500 MPa-far surpassing HDPE's 800 MPa-it ensures superior ring stiffness and remarkable structural integrity, crucial for high-performance applications.
Polypropylene distinguishes itself with its non-toxic, odor-free characteristics, boasting a highly crystalline structure and ultra-light density of 0.90-0.91 g/cm³. Its outstanding water stability is evidenced by a minimal absorption rate of just 0.01%. Additionally, with molecular weights spanning from 80,000 to 150,000, polypropylene excels in molding capabilities, offering a refined, attractive finish, making it the perfect choice for various applications.
The chemical stability of polypropylene is exceptional, allowing it to resist a broad array of chemicals. Caution is advised with concentrated sulfuric and nitric acids. While interactions with certain hydrocarbons may occur, its heightened crystallinity improves its chemical resistance, making it ideal for crafting durable, corrosion-resistant components in a multitude of applications.
As a non-toxic and odorless material, polypropylene surpasses low-density polyethylene with enhanced strength, stiffness, and heat resistance, performing admirably near 100°C. Its excellent dielectric properties and high-frequency insulation remain unaffected by moisture, making it highly versatile for a broad spectrum of industrial and commercial applications.
Exhibiting high resistance to common acids, bases, and organic solvents, polypropylene is the ideal choice for food-grade utensil applications, where safety and durability are paramount.
PPH, a high molecular weight, low melt flow homopolypropylene, benefits from β-modification, yielding a finely crystalline structure that enhances its chemical and temperature endurance, creep resistance, and impact resilience at low temperatures, making it perfect for demanding environments.
