Chopped Glass Microfiber

Chopped Glass Microfiber from Unifrax is designed as a stabilizing additive; our chopped glass microfibers provide unique properties as a reinforcing agent or filler material in rubbers, plastics, paints, adhesives, ceramics and specialty papers. Using a secondary chopping process glass microfibers are cut to shorten the fiber length in order to improve incorporation in compounding processes; while retaining the fibers’ inorganic, noncombustible and high surface area properties.

Unifrax Microfine Glass Fibers have the following outstanding characteristics:

• High specific surface area (SSA)
• Inorganic, inert and noncombustible filler material
• Multiple glass chemistries: B, C & E-glass
• Easy acceptance of surface treatments and coupling agents
• Product grades with average fiber diameters from 0.25μm – 5.0μm
• Fine chopped for improved processing
