2850Polyester Resin Impregnated Fiberglass Tape

 

 

1. Description:   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 lightning arresters.

 

2. Specification:

 

 

 1) Thermal class: H (180C)

 

 2) Loss of weight at calcination: 26% ± 2%

 

3) Tensile strength before curing: ≥ 1000N/cm

 

4) Thickness (mm): 0.17, 0.30

 

5) Width (mm): 10, 15, 20, 25, 30, 50

 

6) Storage time: 2 ~~ 8 months

 

Application 1,Banding tape should be stored in the condition of room temperature. If environment temperature is above 30degree, 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 apply 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.
