II. Raw Materials
Empowered by the robust strength of high-modulus polypropylene, the QDPP equipment achieves peak performance in subterranean drainage and wastewater treatment applications. This extraordinary material, boasting a remarkable elastic modulus of ≥1500 MPa, significantly surpasses HDPE's 800 MPa, greatly enhancing the product's ring stiffness. It stands as a testament to its unmatched structural integrity and durability, ensuring long-lasting excellence.
Our polypropylene is a non-toxic, odorless, and tasteless polymer, celebrated for its lightweight nature and superior crystalline structure. With an exceptionally low density of only 0.90-0.91 g/cm³, it ranks among the lightest plastics available. Its extraordinary stability in water features an absorption rate of merely 0.01%, coupled with a molecular weight ranging between 80,000 to 150,000. This ensures superior molding capabilities and a lustrous, appealing finish that speaks volumes of quality.
Polypropylene's exceptional chemical stability makes it resilient against a broad spectrum of chemical agents. While it withstands many, it is susceptible to erosion by concentrated sulfuric and nitric acids. It may soften in the presence of certain hydrocarbons; however, its heightened crystallinity ensures improved chemical stability. This makes it an ideal choice for corrosion-resistant chemical equipment and components, offering lasting reliability and performance.
This non-toxic, odor-free polymer is distinguished for its low density and outstanding mechanical properties. It excels in strength, rigidity, hardness, and thermal resistance compared to low-density polyethylene, maintaining its functionality at temperatures around 100°C. Its impressive dielectric properties and high-frequency insulation remain unaffected by humidity, making it a versatile choice for numerous applications across various industries.
Its resilience against common acids, bases, and organic solvents makes polypropylene an exceptional material of choice for food utensils and other applications that demand robust chemical resistance, ensuring safety and performance.
PPH, a high molecular weight homopolypropylene, features a low melt flow rate and refined crystalline structure through β-modification. With its superior chemical resistance, remarkable high-temperature endurance, impressive creep resistance, and exceptional low-temperature impact resistance, it is indispensable for demanding industrial applications, ensuring excellence in performance.
