ISOGLAS® F0710, H0720, H0730

Composition

ISOGLAS® F0710 and H0720 and H0730 are unidirectional glass fibre tapes impregnated with thermosetting polyester resin B-staged.

Poperties

ISOGLAS® F0710 and H0720 and H0730 have high tensile strength combined with low elongation and high moisture resistance after curing. The resin system gives sufficient resin flow after application to laminate the tape layers into a compact and resistant bandage.

Applications

ISOGLAS® F0710 is designed for use as winding resistants on DC- traction machines but it is also suitable for end winding bracing of high voltage motors and generators. ISOGLAS® F0710 is also used for the banding of transformer cores.

ISOGLAS® H0720 and H0730 are specially used for motors which are exposed to thermal overloads.

Storablility

Originally packed in polyethylene

Min. 4 months at 30°C
Min. 8 months at 20°C
Min. 16 months at 10°C

ISOGLAS® F0710 and H0720 and H0730 should reach room temperature before opening the original packaging to prevent condensation of water on the tape.

Processing advice

When applying ISOGLAS® tape it is recommended to preheat the armature to about 110-130°C and apply a tension of about 1000 N/cm to the tape. This ensures that > 50% of the applied tension will remain in the bandage after curing and prevents a loosening of teh bandage after cooling down or in service.

After fixing the end of the tape (e.g. with a soldering iron) curing should be done according to listed curing conditions.

Detailed processing advice available on request.
