Heat Resistant E-Fiberglass Needle Mat

Heat Resistant E-fiberglass Needle Mat
CHARACTERISTICS
1. Non-combustibility, high stable chemical properties, excellent insulation material.
2. High recovery rate after compression, shock and vibration resistance.
3. Enormous number of minute air spaces, making it excellent sound absorption.
4. Low shrinkage at high temperature, the shrinkage of FSSP type at 1000° Cis max. 1%.
5. Low thermal conductivity, excellent thermal insulation material.
6. Max. Service temperature 1100° C.
7. After forming pipe, excellent resistance for wind velocity.

Virtues
The product adopts inorganic E type glassfiber along with the main components of silicone Al O and CaO. Also, it is characterized by heat-resistance, tensile strength, tenacity fireproofing, anti-erosion, and good electrical insulation. The adoption of extreme tiny E type glass fibres followed by particular needling leads to numerous thin holes with the glassfibre blanket so as to provide heat-insulation and sound-absorbency.
