A PP flange is a type of flange made from polypropylene plastic. Polypropylene offers similar characteristics to HDPE but may have slightly different properties depending on the specific type of PP used.

Features:

• Affordable and Lightweight: Similar to HDPE flanges, PP flanges are a cost-effective and lightweight alternative to metal flanges.
• Chemical Resistance: Polypropylene offers good chemical resistance to various chemicals, making them suitable for some industrial applications.
• Limited Pressure Rating: PP flanges generally have limitations on pressure handling compared to metal flanges.
• Moderate Temperature Resistance: While better than HDPE, PP flanges also have limitations on high temperatures. Consider the specific temperature rating for the intended application.
