| LANXESS Glass Fiber MF 7980* is suitable for a wide range of applications where the reinforcing properties of glass fibers are needed in combination with small initial fiber length, no surface treatment and excellent flowability. For example, MF 7980 is excellent for reinforcing integral skin polyurethane foams by the RRIM method (RRIM = Reinforced Reaction Injection Molding). Milled fiber is normally stirred into the polyol during processing, but may also be added to the isocyanites. MF 7980 consists of individual filaments of different lengths; Small average fiber length of 190 µm nominally. No treatment/sizing; Also suitable for the reinforcement of thermoplastics (particularly polycarbonates). Adding MF 7980 improves, among other things, heat resistance, stiff-ness, strength and dimensional stability and Excellent flowability Information provided by Lanxess. |
