II. Superior Raw Materials
Our commitment to excellence is evident in our choice of high-modulus polypropylene as the core of our underground drainage and wastewater solutions. Boasting an elastic modulus of ≥1500 MPa, significantly exceeding HDPE's 800 MPa, it ensures extraordinary ring stiffness and formidable structural integrity, paramount for high-performance applications.
Polypropylene is celebrated for being non-toxic and odorless, characterized by a highly crystalline structure and an ultra-light density ranging from 0.90-0.91 g/cm³. Its superior water stability is demonstrated by an absorption rate as low as 0.01%. Furthermore, with molecular weights between 80,000 to 150,000, polypropylene delivers outstanding molding capabilities and a sleek, sophisticated finish, rendering it the preferred material for a multitude of applications.
With its remarkable chemical stability, polypropylene can withstand numerous chemicals, though caution is advised with concentrated sulfuric and nitric acids. It may interact with certain hydrocarbons, but its enhanced crystallinity fortifies its chemical resilience, making it an ideal choice for creating robust, corrosion-resistant components across various applications.
Non-toxic and odor-free, polypropylene surpasses low-density polyethylene with superior strength, stiffness, and heat resistance, proving to be ideal around 100°C. Its excellent dielectric properties and high-frequency insulation, impervious to moisture, make it a versatile material for a wide array of industrial and commercial applications.
Resilient to common acids, bases, and organic solvents, polypropylene is perfectly suited for food-grade utensil applications, where safety and durability are paramount.
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, ideally equipped for high-demand environments.
