basalt fiber needled felt is a kind of porous non-woven felt material with a certain thickness(3-25mm). Basalt fiber with fine diameter is combed and needled by needle felt machine. Numerous small holes are formed in the fiber felt, which makes the product have extremely high heat insulation characteristics. At the same time, basalt fiber high temperature resistance, good electrical insulation products do not contain any adhesive. Basalt felt able to withstand temperatures up 1800°F(982°C) and continue working temperature1400°F(760°C) basalt felt is made of 100% basalt fiber, it's manufactured in various thicknesses and density to suit a broad range of applications. |
Low thermal conductivity. Three dimensional porous structure. Stable chemical properties, no moisture absorption, no midew, no corrosion. Belongs to inorganic fiber,
does not burn, will not produce harmful gases.
(1) Tensile strength≥0.6N/tex，modulus of elasticity≥91GPa,The elongation rate≥2%.Small coefficient of thermal expansion;
(2) Continuous basalt fiber has the advantages of tensile, compressive, stiffness and fatigue resistance balance etc.
(3) It has excellent resistance to chemical corrosion resistance, acid resistance, alkali resistance, salt resistance.
(4)High temperature resistance.
(5) it has good anti ultraviolet radiation performance.
(6) The residual stress on the bonding surface is small.
It can be widely used in the fields of sound insulation, sound absorption, shock absorption, flame retardant, filtration, heat preservation, etc.
1. Advanced air filtering & purification system.
2. Filtering, sound absorption, heat insulation and anti-vibration system in electronic industry.
3. Filtering system of toxic & harmful gas and smoke in chemical industry.
4. Mobile mufflers.
5. Heat insulations and muffler system min vessels and ships.
