Description
This Polypropylene Homopolymer sheet is lightweight and offers excellent chemical resistance. Ideal for various applications including medical and equipment construction.
Material Properties
Polypropylene Homopolymer (PPH) is a lightweight material with a specific gravity of 0.91. It features improved chemical resistance and stiffness, along with a higher working temperature range compared to Polypropylene Copolymer (PPC), which is from 0°C to +100°C. PPH also has low water absorption and is compliant for food use.
Key Features
PPH exhibits excellent weldability and high corrosion resistance. It maintains high rigidity in upper temperature ranges and is food compliant, making it suitable for various applications.
Applications
This material is commonly used in the construction of chemical tanks, water applications, medical equipment, and general equipment construction.
Advantages and Disadvantages
The main advantages of Polypropylene Sheet include its acid resistance, low cost, high impact resistance, and lightweight nature. However, it can be challenging to machine due to its low melting point of 130°C, and bonding can be problematic, often requiring specialized processes.
