Polyester Laminates GPO-3
INSULAC GPO3 is a mineral filled, continuous strand fiberglass-mat-reinforced thermoset unsaturated polyester material. INSULAC - GPO3 exhibits High Flame Resistant, Flame Rating, Combines High Arc and Track Resistance and Asbestos - Free. It is an easily fabricated laminate that exhibits excellent flame resistance. GPO3 is mainly used in the transit industry, where smoke generation and smoke toxicity are of primary concern. It is also recommended for switchgear, connectors and control panels.
Insulac Arc Stack Assembly and Flyback Transformer It has exceptional flame resistance, arc resistance and a high temperature capability for applications such as fly back transformers and arc stack assemblies.
