Acrylic Needle Felt
This kind of needle felt is with good ability of acid and alkali resistance, anti-oxidation, hydrolysis resistance.The major attributes of acrylic fibre are its excellent resistance to hydrolysis, its modest cost compared with the high performance fibers and reasonably high temperature resistance.
It suits middle temperature and high acid, alkali chroma environment. It is widely used in metallurgy, chemical, building material, electric power station, mechanism industry, petroleum, medicine, printing and dyeing, food and beverage, and other industries to filter gas and recycle material.
Features:
- High mechanicalcharacteristics
- Excellent resistanceto hydrolysis
- Optimal heat stabilityboth in dry andwet conditions
- Optimal resistanceto chemical agents
- Extraordinary resistanceto light, weathering,mildew andbacteria
Application:
•Metallurgy
• Chemical, building material
• Electric power plant
•Mechanism industry
• Petroleum
•Printing and dyeing,
• Food and beverage,
• Industries to filter gas and recycle material.
