Industrial filter cloth is a filtration medium woven from natural and synthetic fibers, primarily used for solid-liquid separation. It mainly includes polypropylene (PP) filter cloth, polyester (PET) filter cloth, nylon filter cloth, and vinylon filter cloth.
Polypropylene (PP) filter cloth is widely used in industries such as chemical, pharmaceutical, metallurgy, mineral processing, wastewater treatment, and more. It is commonly paired with solid-liquid separation equipment like press filters and belt filters.
Polyester (PET) filter cloth is made from polyester fibers and is widely applied in pharmaceuticals, food processing, chemicals, metallurgy, and industrial press filters or centrifuge filter cloths.
So, what are the differences between PP and PET filter cloths? Bolian, a specialist in filter cloth industry for many years, tells you that PP and PET can be distinguished by the burning test method and the water immersion method.
Polyester (PET) Filter Cloth:
Polyester easily ignites and burns with black smoke, a yellow flame, an aromatic odour, and hard black-brown ash.
Polypropylene (PP) Filter Cloth:
Polypropylene easily burns but slowly with black smoke, yellow flame at the upper end and blue flame at the lower end, emits petroleum odour, and the ashes are hard round light yellow-brown particles after burning.
Polyester (PET) Filter Cloth:
It sinks when immersed in water with fiber density of 1.2-1.37.
Polypropylene (PP) Filter Cloth:
It floats when immersed in water with fiber density of 0.9-0.92
