| FB72M is heat-resistant/light-stability, flame retardant polypropylene using base resins with superior impact resistance to create high-impact strength characteristics. Due to exceptional light-stability, exposure to ultra-violet light causes little or no discoloration. FB72M is ideal for use in lighting components featuring long-term heat resistance in hot environments.&& |
