When the temperature is below 125 ℃, acrylic exhibits good resistance to organic solvents, oxidants, inorganic and organic acids. Acrylonitrile homopolymers are not easily hydrolyzed, so they are used to replace polyester in low-temperature, chemically corrosive, and humid environments.

According to different requirements of working conditions, our company can perform various functional treatments on acrylic needle punched felt, such as water and oil repellent, PTFE impregnation, coating, laminating, etc.

ACRYLIC NEEDLED FELT is an industrial material with excellent performance and wide application.

1. Material properties

Chemical stability

Polypropylene needle felt has good chemical stability and is resistant to many chemicals. In different chemical environments, such as industrial scenes with weak acids and alkalis, it can maintain its own structure and performance, and is not easily corroded by chemicals and deteriorated or damaged, which makes it stable for use in chemical, printing and dyeing and other industries.

Hydrophobicity

This material has good hydrophobicity. In a humid environment or when filtering gas or liquid containing moisture, it can effectively prevent the adsorption and penetration of moisture. For example, in some humid waste gas treatment processes, polypropylene needle felt can avoid filter material blockage caused by moisture adsorption and ensure the smooth progress of the filtration process.

2. Physical properties

Strength and durability

Polypropylene needle felt has high strength. Through the needle punching process, the fibers are interwoven to form a stable structural network. This structure gives it good tensile strength and is not easy to break or deform when subjected to a certain amount of tension and pressure. In industrial filtration equipment, it can remain intact even under long-term air flow impact or material friction, and has a long service life.

Filtration performance

Its fiber structure determines that it has excellent filtration performance. Its pore size is uniform and moderate, which can effectively intercept particulate matter. In air filtration, it can filter out tiny particles such as dust and pollen in the air; in liquid filtration, it can block impurities, suspended matter, etc. in the liquid, so as to achieve the purpose of purification.

3. Application fields

ACRYLIC NEEDLED FELT plays an important role in many fields. In industrial ventilation systems, it is used as a high-efficiency air filter to ensure the air quality in the workshop; in the water treatment industry, it is used as an important filter material for liquid filtration to improve the purity of water; in the food processing industry, it can be used to filter air, prevent dust and other pollutants from entering the processing area, and ensure the hygiene and safety of food.
