PP (polypropylene) filter cloth is often selected for filtration applications because it offers a number of advantages over other types of filter cloths:

Chemical resistance: PP is resistant to a wide range of chemicals, making it suitable for use in filtering corrosive liquids and gases.

High temperature resistance: PP can withstand temperatures up to 194°F (90°C), making it suitable for use in applications where high temperatures are required.

Great mechanical toughness: PP/polypropylene filter cloth is durable as well as has great tensile toughness, making it appropriate for usage in applications where the cloth will go through high pressures or mechanical anxiety.

Good cake release: PP filter cloth has a smooth surface, which allows for easy cake release during filtration, reducing the amount of time required for cleaning and maintenance.

Cost-effective: PP filter cloth is often less expensive than other types of filter cloths, making it a cost-effective option for many filtration applications.

Overall, PP filter cloth is a versatile and reliable option for a wide range of filtration applications, making it a popular choice for many industries.

Characteristics:
Polypropylene offers good tensile strength and abrasion resistance. They perform well in organic and mineral acids, solvents and alkalies. Polypropylene is attacked by nitric and chlorosulphonic acids, sodium and potassium hydroxide at high temperatures and concentrations.
