Technical Datasheet | Supplied by Brüggemann
BRUGGOLEN® H175 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 long term heat stability in applications up to 150°C. Exhibits efficient process stabilization against yellowing and degradation, best protection of organic pigments against discoloration at high processing temperatures up to approx. 320°C, low volatility during processing, excellent compatibility, low extractability, long term protection of bright colored polyamides against yellowing under aggressive conditions (heat, moisture, chemicals), high efficiency especially in glass-fiber reinforced or mineral-filled polyamides, excellent protection to the finished parts against embrittlement and premature fatigue of mechanical properties under aggressive conditions, both in unreinforced as well as reinforced and filled polymers. BRUGGOLEN® H175 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, dry blending and injection molding. Recommended dosage is 0.2-0.6%. Shelf life is at least 12 months.
