Our high-silica needled
insulation felt is a next-generation inorganic fiber material
designed for superior high-temperature resistance, chemical
stability, and mechanical strength. Composed primarily of
ultra-pure silica fibers, this felt offers excellent thermal
insulation and structural integrity across a wide range of
industrial applications—from aerospace and petrochemical plants to
power generation and automotive systems
Unmatched Thermal
Protection for Demanding Conditions
1.High Heat Tolerance: Performs reliably in extreme temperatures
where conventional insulation fails.
2.Low Thermal Conductivity: Delivers impressive insulation with a
thermal conductivity as low as 0.021 W/m·K.
3.Stable Thickness Range: Available in thicknesses from 3 mm to 30
mm to suit diverse needs.
Chemical & Mechanical
Endurance for Long-Term Use
1.Outstanding Chemical Stability: Resistant to acids, alkalis, and
most corrosive environments.
2.Strong & Flexible: Excellent mechanical strength allows it to
maintain form even under stress.
3.Non-Flammable: Offers natural flame resistance with no added
chemicals or coatings.
Multi-Industry Versatility
with Premium Specifications
1.Aerospace-Grade Performance: Ideal for thermal shielding and
insulation layers in aircraft systems.
2.Energy-Saving Applications: Widely used in power plants and
industrial furnaces to reduce heat loss.
3.Electrical Appliance Insulation: Provides safe, long-lasting
thermal barriers in household and commercial devices.
