II. Superior Raw Materials
Our unwavering commitment to quality is embodied in our selection of high-modulus polypropylene as the cornerstone for our underground drainage and wastewater solutions. With an astounding elastic modulus of ≥1500 MPa-vastly superior to HDPE's 800 MPa-it ensures exceptional ring stiffness and structural integrity, crucial for superior performance applications.
Polypropylene stands out as a non-toxic, odorless material with a highly crystalline structure and an ultra-light density of 0.90-0.91 g/cm³. Its impressive water stability is evidenced by a minimal 0.01% absorption rate. Further, with molecular weights ranging from 80,000 to 150,000, polypropylene offers excellent moldability and an elegant finish, making it the top choice for a multitude of applications.
Polypropylene's chemical resilience is nothing short of extraordinary, enabling it to resist various chemicals, with caution advised only for concentrated sulfuric and nitric acids. While interactions with some hydrocarbons may occur, its superior crystallinity boosts its chemical resistance, rendering it ideal for crafting durable, corrosion-resistant components for numerous applications.
As a material free of toxicity and odors, polypropylene surpasses low-density polyethylene in strength, stiffness, and heat resistance, performing outstandingly at temperatures nearing 100°C. Its excellent dielectric properties and high-frequency insulation remain unaffected by moisture, making it highly adaptable for a broad range of industrial and commercial uses.
Exhibiting remarkable resistance to common acids, bases, and organic solvents, polypropylene is ideally suited for applications such as food-grade utensils where safety and longevity are paramount.
PPH, known for its high molecular weight and low melt flow homopolypropylene characteristics, is enhanced by β-modification, resulting in a finely crystalline structure that augments its chemical and thermal endurance, creep resistance, and impact resilience at low temperatures. This makes it perfect for challenging environments.
