High Silica Needled Mat is made from high silica fiberglass chopped strands through carding and needling processes. After carding, silica chopped strands are sent into the needle loom, randomly distributed and wound together, and punched into mat.
It has good effect of sound absorption and heat insulation.

Storage:
Except where otherwise noted, high silica fiberglass products should be kept in a cool, tidy, dry location. The temperature ranges from 15°C to 35°C, and relative humidity ranges from 35% to 65%. Please do Not unpack its original packing before they will be put into production. The products have no known shelf life when stored properly. However, please retest them 36 months after their initial production date to ensure their good performance.
FAQ
Q: Why does it have two shrinkage rates?
A: The shrinkage rate of 5 is the one after preshrinking treatment, and the rate of 12.5. without preshrinking treatment.
Q: Can you manufacture the silica needled mat according to our specifications?
A: Yes, we are always here meeting your requirements.
Q: What is the filament diameter?
A: It is 9um, another size upon request.
