It protects against yellowing under outdoor conditions and offers very low volatility. It is stable at highest processing temperatures and is very effective in the regeneration of fiber waste materials. Suited mainly for polyamides and polyesters, it can also be used as processing stabilizer against discoloration and degradation, co-stabilizer to antioxidant and in the polymerization of polyamides. BRUGGOLEN® H10 can be processed using extrusion, dry-blending and injection molding. The recommended dosage level is 0.1-0.3% and it has a shelf life of at least 12 months.

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.

BRUGGOLEN® H164 by Brüggemann is a non-discoloring antioxidant and heat stabilizer. It is a synergistic mixture of sterically hindered phenolic antioxidants and phosphonates in powder form. Provides long term heat stability in applications up to 150°C, efficient process stabilization against yellowing and degradation. Exhibits low volatility during processing, no deposits (‘plate-out’) on the finished parts after conditioning, excellent compatibility and low extractability. It offers long term protection of bright colored polymers against yellowing, 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. BRUGGOLEN® H164 is compatible with all polyamides (PA6, PA6.6, PA11, PA12, PA–Copolymers). It can be processed using extrusion, dry blending and injection molding. Recommended dosage is 0.2-0.8%, depending on the polyamide and the desired properties of the finished parts. Shelf life of BRUGGOLEN® H164 is at least 12 months.
