ISOVAL ® 200

ISOVAL ® 200 is in accordance with the following international standards:

IEC 60893

EP GC 203


EP GC 308



ISOVAL ® 200 is prepared from glass fabric impregnated with temperature resistant version of ISOVAL ®  epoxy system.  Laminates exhibit excellent thermal and chemical resistance as well as high mechanical strength at very high temperatures.


ISOVAL ® 200 can be used as a high quality construction material as well as an electric and thermal insulation material in various machines and equipments, especially in those areas, where high operating temperatures are coupled with high mechanical strength requirements.  The extremely good flexural and compressive strength at high temperature enable also application in those areas that traditionally could only be covered by polyimides.  The excellent chemical resistance makes ISOVAL ® 200 an ideal material in the chemical industry.


Thickness: 0.1 – 160 mm Thickness tolerances  

according IEC 60893

Standard sheet size:

2140 + 30/-0 mm x 1040 +30/-0 mm

  2800 + 30/-0 mm x 1220 +30/-0 mm (up to 130 mm thickness)
  3180 + 30/-0 mm x 1220 +30/-0 mm up to 60 mm thickness)
  3180 + 30/-0 mm x 1040 +30/-0 mm (0.2 to 60 mm thickness)
  Machine parts and cuttings are available on request.


Machining  Recommendation

Due to the strength and hardness of the laminate and also the high glass content the tools used can be subject to a great degree of abrasion.  We therefore advise that only diamond carbide tipped tools  and high speed machinery are used.
