Glass Mat


Application Description

Glass-based nonwovens do not absorb moisture and have good dimensional stability and tear strength. They are used in construction as reinforcement for ceiling panels, floors, and insulation and also in roofing shingles. The automotive industry uses glass nonwovens in batteries. Another common use is as veils in composite molding processes. Glass mats often produced by the wet-laid process.

For external use good UV resistance might be important. Softness is only needed during initial shaping or forming so Tg is not usually a key selection factor. For advice on polymers to use in nonwoven glass mat binders and coatings, contact a Product Specialist at MCP.
