II. Raw Materials
Harnessing the formidable strength of high-modulus polypropylene, the QDPP equipment is meticulously engineered for optimal performance in subterranean drainage and wastewater treatment applications. This extraordinary material, with an elastic modulus of ≥1500 MPa, far surpasses HDPE's 800 MPa, significantly enhancing the product's ring stiffness. This is a testament to its unparalleled structural integrity and lasting durability.
Our polypropylene is a non-toxic, odorless, and tasteless polymer, renowned for its lightweight and superior crystalline structure. With an exceptionally low density of merely 0.90-0.91 g/cm³, it ranks among the lightest plastics available. Its outstanding stability in water, evidenced by an absorption rate of just 0.01%, combined with a molecular weight between 80,000 and 150,000, ensures excellent molding capabilities and a lustrous, appealing finish.
Polypropylene boasts exceptional chemical stability, making it resistant to a wide array of chemical agents. Although resilient against many, it is susceptible to erosion by concentrated sulfuric and nitric acids. It may soften in the presence of certain hydrocarbons, yet its superior crystallinity ensures enhanced chemical stability, rendering it an ideal choice for corrosion-resistant chemical equipment and components.
This non-toxic, odor-free polymer is celebrated for its low density and outstanding mechanical properties. It excels in strength, rigidity, hardness, and thermal resistance when compared to low-density polyethylene, maintaining its functionality at temperatures up to 100°C. Its impressive dielectric properties and high-frequency insulation remain unaffected by humidity, making it an ideal choice for diverse applications across industries.
Its resistance against common acids, bases, and organic solvents makes polypropylene an exceptional material for food utensils and other applications requiring robust chemical resistance.
PPH, a high molecular weight homopolypropylene, features a low melt flow rate and refined crystalline structure through β-modification. With superior chemical resistance, remarkable high-temperature endurance, impressive creep resistance, and exceptional low-temperature impact resistance, it is indispensable for demanding industrial applications.
