II. Raw Materials
Harness the unparalleled capabilities of high-modulus polypropylene-your ultimate ally in efficient drainage, sewage, and wastewater management. Boasting an impressive elastic modulus of ≥1500 MPa, it outshines HDPE by delivering unmatched ring stiffness, ensuring robust and reliable performance for varied applications. Its superior material properties elevate it as the quintessential choice for subterranean infrastructure solutions.
Embrace the lightweight elegance of polypropylene, a non-toxic, odorless, and tasteless crystalline polymer, celebrated for its minimal density of just (0.90-0.91 g/cm³). This distinguished plastic offers exceptional stability in aqueous environments, with a mere 0.01% absorption rate. Its substantial molecular weight, ranging from 80,000 to 150,000, coupled with superb molding capabilities and a lustrous finish, makes it a versatile star in modern material science.
Polypropylene stands as a paragon of chemical stability, resilient against numerous reagents while maintaining integrity. Although vulnerable to concentrated sulfuric and nitric acids, it exhibits resilience by resisting low molecular weight hydrocarbons. With increased crystallinity, its chemical durability is optimized, making it an ideal candidate for manufacturing high-grade components that demand superior corrosion resistance.
Polypropylene's non-toxic, odor-free nature, combined with low density, sets it apart. It offers an impressive trifecta of strength, rigidity, and thermal endurance, outperforming low-density polyethylene. Capable of withstanding temperatures around 100°C, its dielectric properties and exceptional high-frequency insulation remain unaffected by humidity, ensuring reliable performance across varied applications.
Unaffected by common acids, bases, and organic solvents, polypropylene is well-suited for use in the culinary arena, making it the material of choice for food-grade utensils, upholding safety and durability standards.
Experience the excellence of PPH, a high molecular weight, low melt flow rate homopolypropylene, ingeniously enhanced through β-modification. This sophisticated process endows it with a refined crystalline structure, bestowing remarkable chemical, thermal, and creep resistance. Its stellar impact resistance at low temperatures endorses it as an exemplary material for demanding environments.
