A new high-tech heat stabilizing system has been developed by Lanxess, Pittsburgh, and is being applied to the company’s Durethan nylons for demanding applications in the electrical and electronic sectors and automotive underhood, particularly in the oil circulation system.

XTS3 (Xtreme Temperature Stabilization), like its predecessor XTS1, raises the continuous service temperatures that nylons 6 and 66 can withstand by around 140˚F to 392˚F. However, the heat stabilization properties of XTS3 are based nor on a inorganic but an organic additive system that is metal- and halide-free. Nylons that incorporate this stabilizer system are said to be ideal for manufacturing plastic parts that are subjected to high thermal loads and come into direct contact with metal components. This metal- and salt-free stabilizer ensures there is not contact corrosion.

The first two materials with the new stabilization are 30% short glass reinforced Durethan BKV 30 XTS3 nylon 6 and AKV 30 XTS3 nylon 66. Potential applications in the engine compartment include oil filter housings, oil pans, housings of transmission control systems and sensors that come into contact with oil, while those in the E/E sectors include plug connectors, plug strips and housing parts. Both grades boast an excellent price-performance ratio and high processing stability, and in some applications, can be an alternative to costly heat-stabilized specialty resins such as PPS, semi-aromatic nylons and nylon 46.
