RALUPOL® UP 4806

Chemical Family: Polyesters

RALUPOL® UP 4806 molding compounds are characterized by excellent dimensional stability with very low processing and post-shrinkage. Due to their high rigidity and excellent heat resistance, RALUPOL® products withstand short-term heat loads. They have excellent electrical insulation and dielectric properties, which are retained even with long-term use at high temperatures. The reason for this is high tracking resistance (CTI> 600 V), arc resistance, glow wire test (GWFI 960 ° C) and a high electrical RTI (relative temperature index) of 170 ° C according to UL 746 (IEC 60216 / T1).
