BRUGGOLEN® H11

BRUGGOLEN® H11 by Brüggemann is a synergistic mixture of sterically hindered phenolic antioxidants and phosphonates in powder form. Acts as an antioxidant and heat stabilizer. Provides an 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. Imparts 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, long term protection of bright colored polymers against yellowing. Compatible with polyamides (PA6, PA6.6, PA11, PA12, PA–Copolymers). Recommended dosage is 0.2-0.8%, depending on the polyamide and the desired properties of the finished parts. It has a shelf life of at least 12 months.
