Phenolic Plus BRUGGOLEN TP-H1803 bridges the price-performance gap in polyamide heat stabilization

Brüggemann’s Phenolic Plus BRUGGOLEN TP-H1803 is a new heat stabilizer for polyamides designed to outperform conventional phenolic/phosphite based stabilizers, i.e. blends of sterically hindered phenolic antioxidants with organic phosphites. BRUGGOLEN TP-H1803 bridges the price-performance gap between these blends and copper based stabilizers.

Phenolic Plus extends the heat stabilization of polyamides to peak temperatures of 180°C, something not possible for hindered phenolic antioxidants and organic phosphites. Furthermore, due to the high efficiency of Phenolic Plus, lower dosages are possible than those needed by conventional phenolic/phosphite blends in order to achieve the same effect. For example, in trials at 150°C, the dosage of Phenolic Plus BRUGGOLEN TP-H1803 could be reduced by 30% compared to that of a standard stabilizer package, whilst still maintaining the same level of tensile strength retention after heat aging.

Compared to commercially available blends of sterically hindered phenols and phosphites, Phenolic Plus BRUGGOLEN TP-H1803 extends the stabilization of polyamides at a similar cost in use.

Brüggemann supplies BRUGGOLEN TP-H1803 in the form of dust-free pellets which can be easily metered and readily dispersed and are suitable for both compounding and injection molding.
