Polyester resin impregnated glass fiber banding tapes

     "HaiYing"H180, F155,B130 banding tapes consist of parallel twisted E-glass yarns preimpregnated with a special thermosetting polyester resin. The banding tape is pliable and tacky. Its web structure provides easy unwind without glass strands separation and overlapping.The product contributes the characteristics of high tensile strength, high resistance to shocks, high modulus of elasticity, dimensional stability as well as no magnetically confining and eddy currents losses, which can be widely used as ideal banding materials for electrical motors, transformers and lightening arresters.

Application Instruction of Banding Tape

1、Banding tape should be stored in the condition of room temperature. If environment temperature is above 30℃, the products should be put in the freezer.
2、The testing of properties (for example: test volatile content) should be carried within one hour after the banding tape is taken from the plastic bag.
3、When applying the banding tape, keep it in the plastic bag at the room temperature for 24 hours after taking out from the freezer.
4、During the process of application, uneven tension and unsmooth banding would make the tape separation. You could continue to use after neatening the remaining pancake. 
5、Banding process should proceed at the room temperature. Better effect will obtain if the process is put up at the heat condition.
　　Heat banding process is as follows: 
　　A.Preheat the work piece at the temperature 80℃ for one hour. 
　　B. Prereheat the banding tape at the temperature 40℃±5℃ for 20 minutes. Preheat can not be over the time to avoid the tape to be cured in advance,. The tape preheated should be used up once.
6、Certain tension should be applied to the banding tape. Tension is less than 1000N/cm for 0.30mm thick tape , The speed is good enough at 10m-15m /min.
7、 In order to prevent the loosen of the tape, its end should be locked when the banding work finished. Insert the end into inner layer of the tape and press tightly.
8、It is recommended to cure the finished banding work piece continuely at several stage: 80℃ for 1 hour; 120℃ for 1 hour; 155℃ for 3 - 4 hours. It needs 6 hours for tractor motor and industrial large motor ( above-mentioned exclude the time for work piece to reach the curing temperature). 
9、 If you would treat dry process of varnish dipping and curing of banding tape together, it is necessary to do a trial to make sure that the dry process will not affect the curing of banding tape.
10、If you want banding process by hands, richer resin and higher volatile content type tape than normal of ours is suitable for you.
