Composition

ISOGLAS® F 0710 and H 0720 and H 0730 are unidirectional glass fibre tapes impregnated with thermosetting polyester resin B-staged.

Properties

ISOGLAS® F 0710 and H 0720 and H 0730 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® F 0710 is designed for use as winding restraints on DC-traction machines but it is also suitable for endwinding bracing of high voltage motors and generators. ISOGLAS F 0710 is also used for the banding of transformer cores. ISOGLAS® H 0720 and H 0730 are specially used for motors which are exposed to thermal overloads.

Availability

Tapes: approx. 200 m long: 10, 15, 20, 25, 30 mm width.

Inner diameter of the core: 82 mm

Packing: each roll individually sealed in polyethylene.

Storability

Originally packed in polyethylene:

• Min. 6 months at 20° C.
• Min. 12 months at 5° C.

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 the 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.
