Isoval 11, G11 Epoxy Fibreglass Sheet 0.2mm x 1040mm x 2140mm

• Premium Quality Epoxy Laminate Sheet with Layers of Fibreglass Reinforcement.
• Meets or Exceeds All Requirements of NEMA G11.
• Excellent Temperature Resistance (180°C), Mechanical Strength and Machinability.
• Manufactured in Europe by Isovolta.

Our Isoval 11 is a high quality, high performance grade of epoxy laminate used for all kinds of electrical insulation and mechanical support applications. This material is manufactured from heat resistant epoxy resin which is used to laminate layer upon layer of fibreglass. The result is a rigid, high strength sheet that can be cut or machined accurately and exhibits excellent electrical & thermal properties.

Isoval 11 meets or exceeds all requirements of NEMA G11 (and more). This quality rigid electrical insulation board is manufactured in Europe by Isovolta and is widely used throughout Australian industry and around the world. Some of the more important benefits and features of this epoxy glass sheet are expanded upon below while more technical details are covered on our Isoval 11 Technical Data Sheet.

Excellent Dielectric Strength and Electrical Insulation Properties.

Isoval 11 Epoxy Sheet is most commonly used for electrical insulation purposes. In these applications, it excels as it offers superior dielectric strength, breakdown voltage and electrical properties. These are summarised with the values below (more available on the TDS).

Very Good Heat Resistance and Thermal Endurance.

Isoval 11 has been tested for thermal endurance in accordance with the stringent requirements of European Standard IEC 216. In this test, Isoval 11 recorded a thermal index rating (TI) of 180. This ensures that this high-quality laminate is capable of withstanding maximum operating temperatures of 180ºC long term.

Isoval 11 Epoxy Fibreglass Laminate can be used in electrical applications up to and including Class H.

Mechanical Strength and Machinability.

Isoval 11 is a strong, rigid type of epoxy board that has excellent endurance, machinability and physical strength. It can be accurately machined to tight tolerances and has a high glass content which helps it withstand abrasion.

Since it’s been trusted and specified for decades, numerous aspects of this laminates physical strength have been tested over the years. Some of these are summarised in the table below with many more included on our Isoval 11 TDS.

Meets or Exceeds Numerous International Standards.

Isovolta Isoval 11 Epoxy Glass is used by some of the world’s leading electrical machinery manufacturers and has been rigorously tested and certified. This laminated electrical insulation board conforms to the following international standards:
