产品说明

High-viscosity, plasticizer-free extrusion compound with an extraordinary longterm heat resistance

VESTAMID LX9008 is a plasticizer-free polyamide 12 compound, with an especially high long-term resistance under thermal load.

VESTAMID LX9008 is suitable to produce flexible tubes that are permanently exposed to higher temperatures, e.g., in the engine compartment of motor vehicles. Especially when used as diesel fuel lines they show significant advantages compared with standard grades, obvious in storage tests

with diesel fuel (see the figure).

The material absorbs only little moisture, thus leading to nearly unaffected dimensions and properties of the finished parts at changing ambient conditions.

Using VESTAMID LX9008 for fuel lines one must pay attention to certain preconditions. The Technical Marketing Department gives you advice in selecting the suitable VESTAMID compound.
