ISOVAL ® 200

ISOVAL ® 200

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

IEC 60893

EP GC 203

 

EP GC 308

NEMA LI 1 G11

Composition

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.

Application

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.

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.
