Polyester blended needle punched felt
Polyester composite conductive fiber needle punched felt is mixed with about 5% of conductive fiber into polyester fiber. The needle punching reinforcement technology has excellent antistatic effect, and it can endure all kinds of dyeing, finishing, washing and antistatic performance for a long time.
* the polyester fiber can also be used in combination with polypropylene, acrylic and other medium low temperature materials.
【Polyester mixed conductive fiber needling filter felt】
Application area
It is widely used in steel, cement, chemical industry, power generation, smelting, building materials, pharmaceutical, grain, food, processing, casting and other industries.
Matters needing attention
1. avoid the use of high temperature alkaline conditions;
2. the fire source and the heat source are isolated.
