About ISOVOLTA
ISOVOLTA AG is an international manufacturer of electrical insulation materials, technical laminates and composite materials headquartered in Wiener Neudorf, Austria. Founded in 1949 in Werndorf near Graz, the company belongs to Constantia Industries AG and employs more than 1,500 people at around 15 production and sales locations in 11 countries. With its own infrastructure, ISOVOLTA covers the entire value chain: in its in-house laboratory, customer-specific resin systems are formulated; subsequently, fabrics, nonwovens, papers, glass and films are impregnated and coated, pressed into laminates, tubes and rods, and further processed. The portfolio comprises prepregs, layered laminated materials such as hard paper and hard fabric, CFRP laminates, GFRP rings, high-performance plastics, mica papers as well as technical and decorative laminates. Around 20 industries – from electronics, transformer and mechanical engineering to power generation and distribution, aerospace and automotive – rely on the products. The Group supplies worldwide with an export share of over 90%.
