What is the difference between polyester (PE) liquid filter bags and PP liquid filter bags?

PP is the abbreviation of polypropylene, Chinese is polypropylene, which is a polymer formed by addition polymerization of propylene. It is a white waxy material with a transparent and light appearance.

The interior of the pp material is mainly made of high-purity propylene, which includes a small amount of ethylene copolymer. After drying, mixing, extrusion, granulation, sieving and homogenization, star polypropylene particles are The cylindrical particles are very smooth and clean without any mechanical impurities. It has good mechanical properties and heat resistance. It is non-toxic when used in the temperature range of minus 30 degrees Celsius to 140 degrees Celsius.

Polypropylene is a thermoplastic synthetic tree finger with excellent performance, which is a colorless and translucent thermoplastic lightweight general-purpose plastic. It has chemical resistance, heat resistance, electrical insulation, high-strength mechanical properties and good high wear-resistant processing properties, etc., which makes polypropylene rapidly used in machinery, automobiles, electronic appliances, construction, textiles, packaging since its inception. It has been widely developed and applied in many fields such as agriculture, forestry, fishery and food industry.

PET polyester.

Polyester fiber, commonly known as "polyester". It is the largest variety of synthetic fibers at present. The biggest advantage of polyester fiber is that it has good wrinkle resistance and shape retention, and has high strength and elastic recovery. It is durable, wrinkle-resistant, iron-free, and non-sticky. Therefore, polyester is also a common raw material for clothes.
