II. Superior Raw Materials
Demonstrating our unwavering commitment to quality, we have selected high-modulus polypropylene as the foundation of our underground drainage and wastewater solutions. With an impressive elastic modulus of ≥1500 MPa, significantly surpassing HDPE's 800 MPa, it guarantees exceptional ring stiffness and robust structural integrity, vital for high-performance applications.
Polypropylene is distinguished by its non-toxic, odorless nature, featuring a highly crystalline structure and ultra-light density of 0.90-0.91 g/cm³. Its exceptional water stability is demonstrated by an absorption rate of just 0.01%. Furthermore, with molecular weights ranging from 80,000 to 150,000, polypropylene excels in molding capabilities and offers an elegant, attractive finish, making it the material of choice for a myriad of applications.
The chemical stability of polypropylene is noteworthy, enabling it to resist a vast array of chemicals. While caution is necessary with concentrated sulfuric and nitric acids, its enhanced crystallinity boosts its chemical resistance, making it perfect for crafting durable, corrosion-resistant components in numerous applications.
As a non-toxic and odor-free material, polypropylene exceeds low-density polyethylene with superior strength, stiffness, and heat resistance, performing admirably even near 100°C. Its excellent dielectric properties and high-frequency insulation remain unfazed by moisture, rendering it versatile for an extensive range of industrial and commercial applications.
Demonstrating high resistance to conventional acids, bases, and organic solvents, polypropylene is ideal for food-grade utensil applications, where safety and durability are of the utmost importance.
PPH, a high molecular weight, low melt flow homopolypropylene, benefits from β-modification resulting in a finely crystalline structure that enhances its chemical and temperature endurance, creep resistance, and impact resilience at low temperatures, making it suitable for challenging environments.
