Optical Brighteners / Whitening Agents for Plastic Compounds

BRUGGOLEN® L11 by Brüggemann is a mixture of optical active substances, heat stabilizers and processing auxiliaries. Acts as light stabilizer and optical brightening agent. Provides compensation of yellow discoloration caused by degradation during processing or by long-term exposure to light, processing stability up to processing temperatures of 320°C, excellent compatibility to polymers and low extractability. It is compatible with polyamides (PA 6, PA 6.6, PA 11, PA 12, PA-copolymers), polyesters (PET, PBT), styrenics (ABS, SAN). Offers excellent protection both in unreinforced and glass-fiber reinforced or mineral-filled polymers. It offers an excellent protection both in unreinforced and glass-fiber reinforced or mineral-filled polymers. BRUGGOLEN® L11 can be processed using dry blending, extrusion and injection molding. Recommended dosage is 0.05-0.3%. It has a shelf life of 12 months.
