This is a fibreglass braid saturated in acrylic varnish making it a tough and flexible insulation material. It possesses good electrical and mechanical strength and has excellent compatibility with Class F impregnating resins and varnishes, making it ideal for protecting electrical conductors and terminals.
Please note: Care should be taken to minimise dust formation during handling and cutting this glass based material as dust or broken particles may cause skin irritation.
