Essen, Germany – Evonik is expanding its portfolio of polyamide 12 compounds for insulating electrical conductors with the product Vestamid LX9050 OR. By using halogen-free flame retardants in accordance with IEC 60754, the compound meets the requirements for classification V-0 of its flammability according to UL94. Busbars insulated with the new RAL 2003 signal orange colored material can be used at elevated operating temperatures up to 125°C.
The copper or aluminum profiles are coated by co-extrusion, and the favorable processing properties of Vestamid LX9050 OR also allow higher extrusion speeds. Adhesion to the metal core is excellent; adhesion promoters are not required. Due to the high elasticity of the compound, the coated busbars can be shaped very well after extrusion and even bent with small radii without losing the protective effect of the Vestamid insulation.
The compound is also suitable for processing in injection molding. Because of the halogen-free flame retardants used, it can also be used to manufacture other components for automotive electrics or for the electrical industry. The newly developed compound with a flammability classification of V-0 completes Evonik’s existing range of other RAL signal orange polyamide 12 products with V-2 and HB classifications. Vestamid has been valued in the electrical and electronics industry for decades and is also used in cable insulation, among other applications
