• High porosity, connected by fiber wire → excellent sound absorption → three-dimensional grid structure → good insulation effect.

• Its flammability → No need to add flame retardants to reach B1 level standards, no dripping, no toxic smoke.

• Thermal stability → long-term operating temperature -180℃- +200℃.

• Flexible filament → Excellent cleaning effect.

• Chemical stability → Resistance to weak alkali and acid.

• Sound absorption, heat insulation, easy to clean, characteristics of strong flame retardant, good cleaning effect.
