Epoxy Resin Impregnated Web Fiberglass Banding Tape

Product Description
"Haiying"H180, F155, B130 banding tape is made from continuous fiberglass yarns, high tensile electrical grade glass yarn, impregnated with thermosetting epoxy base resin. The yarns are laid parallel or web to form a thin flat ribbon & utilizing maximum tensile strength of the glass to give an exceptional strength.

Product Feature
As supplied the banding tape is soft & pliable with a slight amount of tack. During the cure the resin flows & fill voids & air space to produce a homogenous laminate. Finally, the fully cured band is rigid with a hard-smooth resin rich surface & forming a void free homogenous mixture of glass & resin. After application and curing the tape holds the body in radial compression.

Application
HAIYING Polyglass tape is a High strength, resin-impregnated, moisture resistant, fiberglass tape, 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 30oC, 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. Pre-heat the work piece at the temperature 80oC for one hour.
   B. Pre-heat the banding tape at the temperature 40oC±5oC for 20 minutes. Preheat cannot 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 continually at several stage: 80oC for 1 hour; 120oC for 1 hour; 155oC 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.
