BRUGGOLEN® H161

BRUGGOLEN® H161 by Brüggemann is a synergistic mixture of sterically hindered phenolic antioxidants and phosphonates in powder form. Acts as a non-discoloring antioxidant and heat stabilizer. Provides excellent protection against embrittlement and premature fatigue of the mechanical properties of the finished parts under long term stress, both in unreinforced and glass-fiber reinforced or mineral-filled polymers. Offers long term heat stability in applications up to 150°C, efficient process stabilization against yellowing and degradation, low volatility during processing, excellent compatibility, low extractability, high efficiency especially in glass-fiber reinforced or mineral-filled polyamides, complete dispersion, giving clear transparent films and fibers, no deposits (‘plate-out’) in fiber spinning. BRUGGOLEN® H161 is compatible with polyamides (PA6, PA6.6, PA11, PA12, PA copolymers), but also in other thermoplastics such as polyesters (PET, PBT), polycarbonates (PC) and their blends, styrenics (PS, ABS, SAN) and polypropylene (PP). It can be processed using extrusion, injection molding and dry-blending. Recommended dosage is about 0.2-1.0%, depending on the polymer and the desired properties of the finished parts. It has a shelf life of at least 12 months.
