Resin Glass Banding Tape
Nashik Insulations Resin Glass Banding Tape is a high strength non-woven glass tape used for banding of rotor, armatures and transformer core. It consists of high strength glass yarns laid parallel, impregnated with special high temperature thermosetting polyester resin. During cure, the resin flows and fills the voids and air spaces to produce a homogeneous laminate with a smooth resin surface.

Recommended Application:
- As a winding restraint on traction armatures, generators other rotating machines & transformer core binding.
- Other applications where high tensile strength and insulating properties of the product can be made use of.
Features :
- High Thermal Resistance of up to 200°C. A short period of heating up to 260°C may be tolerated, whereas solder may melt on steel wires.
- Very high Arc Resistance thereby minimizing the possibility of “flash-over” which has often been a problem with steel bands.
- Resistant to humidity and corrosion.
- A smooth cured surface on the application of banding tape reduces dirt adhesion, which might otherwise lead to tracking failure.
- Non-conducting material, hence eliminating insulation as required under steel banding.
- Prevents Lashing banding tape bands gone far in eliminating the extreme damage caused by lashing wires & lifting armature coils experienced when steel bands break.
- Composite material Banding Tape is supplied in a semi-cured soft balanced flat ribbon of glass yarn & high temp. polyester resin. Thus ensuring that each yarn bears a distributed share of the load. Banding Tape forms a high-strength loop, holds the coil in place against centrifugal forces and has a high safety factor, once suitably applied under requisite winding tension & cured to recommended cycle. Supports weight reduction as compared to steel banding wire.
Application Care :
Due application care is recommended for optimum performance. It is advised that the banding procedure be standardized on the basis of the job & monitored for compliance with process parameters to obtain the desired performance. Generally for the banding tape, in addition to product quality and storage condition, the method of use plays an equally important role in product performance.
Storage :
Resin Glass Tape should be stored in a low-temperature atmosphere. See shelf-life guidelines on the next page. The tape should be brought back to the ambient condition at the time of use. Except at the time of use it is best to put Banding Tape in a plastic cover and seal it to keep it clean and to avoid condensation of moisture on the product at low temperatures.
Transportation :
Resin Glass Banding Tape requires special/quick transportation arrangements. Mutual consultation is suggested for appropriateness depending on the transit period, available modes, handling, etc. Considering the sensitivity of Resin Glass Banding Tape promptness is required by the buyer to take delivery of the consignment and store it suitably.
