Brüggemann has launched its Phenolic Plus BRUGGOLEN TP-H1803, a new heat stabiliser for polyamides designed to outperform conventional phenolic/phosphite based stabilisers, 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 stabilisers.
Phenolic Plus extends the heat stabilisation of polyamides to peak temperatures of 180°C, something not possible for hindered phenolic antioxidants and organic phosphites.
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 per cent compared to that of a standard stabilier package, whilst still maintaining the same level of tensile strength retention after heat aging.
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 moulding.
