Basalt Fiber Needled Felt

Product Summary
Continuous basalt fiber needled felt is made by random entanglement of single fibers to form a three-dimensional structure. There is the large surface area of the 5.5-7¨ªm fine fibers and about 80% porosity, no boron. Basalt fiber needled felt can be used in high efficiency air filtration and purification, heat and sound insulation, and used as cushion material for hot rolling of steel and aluminum.
Application:
- Advanced air filtration system;
- Filtration, acoustic absorption, heat insulation and vibration proofing systems in electronic industry;
- Poisonous gas and dust filtration systems in chemical industry;
- High-temperature resistance, environmental protection automobile mufflers;
- Heat insulation and acoustic absorption system of vessels and ships.
