What is PP Polypropylene?

PP (Polypropylene) is a high-performance thermoplastic commonly used in industries requiring chemical resistance and mechanical strength. Compared to PE-HD (PE 300), it is slightly stiffer and harder. Due to its superior resistance to organic compounds and chemicals, polypropylene is widely utilized in producing containers, wastewater treatment systems, fish farming tanks, and outdoor pools. It’s also extensively used in hot tub manufacturing, with color options including blue. PP is easy to process, allowing for cutting, milling, bending, and drilling. However, due to its chemical inertness, bonding is difficult, and welding is the preferred joining method.

Applications of PP Polypropylene

Food Industry

PP is extensively used in the food industry to manufacture containers and storage tanks for food processing and packaging, thanks to its non-reactive nature and compliance with safety standards.

Chemical Industry

Its high resistance to acids and alkalis makes PP an ideal material for chemical storage tanks, pipelines, and wastewater treatment systems, ensuring durability in aggressive environments.

Aquaculture

PP is a preferred material for fish farming reservoirs and tanks due to its excellent water resistance and structural rigidity, ensuring long-term use in aquatic environments.

Recreational Products

Due to its durability and flexibility, PP is commonly used in manufacturing hot tubs and outdoor pools. It can be easily thermoformed and customized in various shapes and colors.

Types of PP Polypropylene

PP-H AlphaPlus (Homopolymer)

• Density: 0.91 g/cm³
• Working Temperature: 0°C to +100°C
• Forms: Sheets, rods, welding rods
• Colors: White, light gray (RAL 7032)

Recommendation: PP-H is suitable for high-temperature applications and is available in custom-cut sizes for convenience.

PP-C (Copolymer)

• Density: 0.91 g/cm³
• Working Temperature: -20°C to +80°C
