II. Superior Raw Materials
Our steadfast dedication to unmatched quality is highlighted through our selection of high-modulus polypropylene as the cornerstone of our underground drainage and wastewater solutions. Boasting an extraordinary elastic modulus of ≥1500 MPa, significantly outstripping HDPE's 800 MPa, it delivers exceptional ring stiffness and robust structural integrity, crucial for high-performance applications.
Polypropylene sets itself apart as a non-toxic, odorless material characterized by its highly crystalline structure and ultra-light density of 0.90-0.91 g/cm³. Its superior water stability is evidenced by an absorption rate of merely 0.01%. Additionally, with molecular weights ranging from 80,000 to 150,000, polypropylene excels in molding versatility and offers a sleek, attractive finish, making it the material of choice for a wide range of applications.
The chemical stability of polypropylene is truly exceptional, enabling it to endure various chemicals; caution is only needed with concentrated sulfuric and nitric acids. Although it may react with certain hydrocarbons, its enhanced crystallinity augments its chemical resistance, rendering it an ideal choice for creating durable, corrosion-resistant components across a multitude of applications.
Polypropylene, being a non-toxic and odor-free material, surpasses low-density polyethylene with its superior strength, stiffness, and heat resistance, maintaining excellent performance near 100°C. Its outstanding dielectric properties and high-frequency insulation remain unhindered by moisture, making it versatile for a vast range of industrial and commercial applications.
Exhibiting remarkable resistance to common acids, bases, and organic solvents, polypropylene is perfectly suited for food-grade utensil applications where safety and endurance are paramount.
PPH, distinguished by its high molecular weight and low melt flow homopolypropylene, is enhanced through β-modification, resulting in a finely crystalline structure that improves its chemical and temperature resistance, creep resistance, and impact resilience at low temperatures. This makes it the perfect selection for demanding environments.
