II. Superior Raw Materials
Our unwavering commitment to exceptional quality is vividly demonstrated through our choice of high-modulus polypropylene as the foundation of our underground drainage and wastewater solutions. With an impressive elastic modulus of ≥1500 MPa, far surpassing HDPE's 800 MPa, it offers unmatched ring stiffness and robust structural integrity, critical for high-demand 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 highlighted by an absorption rate of just 0.01%. Additionally, with molecular weights ranging from 80,000 to 150,000, polypropylene excels in molding versatility and provides a smooth, attractive finish, making it the preferred choice for a wide array of applications.
The chemical stability of polypropylene is truly remarkable, allowing it to withstand a wide array of chemicals; caution is only necessary with concentrated sulfuric and nitric acids. Although it may react with certain hydrocarbons, its enhanced crystallinity boosts its chemical resistance, making it an ideal option for creating durable, corrosion-resistant components for numerous applications.
Polypropylene, as a non-toxic and odor-free material, outstrips low-density polyethylene with its superior strength, stiffness, and heat resistance, maintaining stellar performance near 100°C. Its exceptional dielectric properties and high-frequency insulation remain unaffected by moisture, ensuring versatility for a wide range of industrial and commercial applications.
Exhibiting exceptional resistance to common acids, bases, and organic solvents, polypropylene is perfectly suited for food-grade utensil applications where safety and durability are essential.
PPH, characterized by its high molecular weight and low melt flow homopolypropylene, is enhanced through β-modification, resulting in a finely crystalline structure that boosts its chemical and temperature resistance, creep resistance, and impact resilience at low temperatures. This makes it the perfect choice for demanding environments.
