Fiberglass Needled Mat

Jun 4th, 2008 | By admin | Category: Fiberglass Mat
Fiberglass needled mat is a mechanically bonded e-glass glass fiber insulation blanket of uniform density. It is manufactured from a well-controlled assortment of long textile glass fibers to ensure uniform mechanical bonding with no additional binders. The resulting product has excellent insulation efficiency for extended exposure at high temperatures. Also good for sound insulation and filtration applications.

E-glass needled mat - excellent quality at a competitive price
