Bruggolen TP-H1606 Heat Stabilizer

Extends the Long-Term Service Life under Heat

Bruggolen TP-H1606 is a new copper complex-based heat stabilizer from BrüggemannChemical with low halogen content, which allows a significant increase in the long-term service life under heat compared with conventional blends of sterically hindered phenols and phosphites. This applies particularly at low and medium temperatures up to 150°C.

In addition, it offers the effectiveness known from copper stabilizers at elevated temperatures up to 180 °C. It is color-neutral (even after conditioning) and is thus also suitable for natural-color products or lighter shades. The wide field of application, which includes the E&E sector, is also demonstrated by the fact that the stabilizer is neither subject to labeling (according to GHS), nor exerts any significant influence on the comparative tracking index (CTI).

The new additive can be accurately metered, disperses readily in polyamide and is ideal for the compounding of these plastics. Polyamide grades stabilized with this product can be processed without problem in the customary way, both in injection molding and in extrusion.

With Bruggolen TP-H1606, it is possible to stabilize polyamides so that the mechanical properties under heat remain constant for a very long time at a high level, thus enabling the final products to continue functioning in use very much longer and without failure. For example, with an unreinforced polyamide 6.6 stabilized with 0.5 % of TP-H1606, a half-life of the elongation at break of over 2000 h is obtained after aging at 120°C. At twice the dosage, over 4000 h is even possible. In comparison, when 0.5 % of a conventional phenol/phosphite blend is used, the half-life of the elongation at break barely reaches 1000 h. Even if the concentration is doubled, the time is only 1300 h, which represents a fraction of the value obtainable with the same dosage of Bruggolen TP-H1606. With the aid of the new additive, the long-term performance can be specifically prolonged and adjusted to the demands of the application. All this means that materials produced with this product open up new ways for the further substitution of complex metal structures through much lighter and cheaper – and in some cases, highly integrated – injection molded parts.
