fiberglass in shanghai "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 trands 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. Polyester glass Tape (2830) Specifications: 1) Thermal class:B (130C) 2) Loss of weight at calcination: 26% ± 2% 3) Tensile strength before curing: ≥ 1000N/cm 4) Thickness (mm): 0.17, 0.2,0.30 5) Width (mm): 10, 15, 20, 25, 30, 50 6) Storage time:2 8months Outer packing: Carton Dimensions: 300 x 300 x 300mm The characteristic 1,Web Banding Tapes are divided into thermal class H;F. Parallel Banding Tape is thermal class B. 2,The thickness of tapes are 0.17mm,0.30mm,0.33mm. The width of tapes ranges from 6mm to 50mm. The length of each pancake ranges from 50 to 200 meters. The spools are from 1500 to 2000 meters. 3,Two kinds of resin, polyester and epoxy resin are impregnated for banding tapes. Polyester resin impregnated banding tape possessed longer storage time. 4,The tapes provide high tensile strength before curing. It reaches more than 1500 N/cm for 0.30mm thick tape. 5,The tapes need short curing time, 4 – 5 hours at 155C (continuely curing ). 6,Tapes have good dielectric, more than 12kv per milimeter. 7,Banding tapes contribute long storage time, six months at 25C ( three months for epoxy resin impregnated banding tape). They are good for storage, avoiding wasting. 8,The products are easy unwind and high efficiency application.
