The 50mm insulation filament tape 50 Meter combines a pressure sensitive adhesive layer with a fiberglass filament reinforced backing that resists tearing in both directions. Standard adhesive tapes tear easily when pulled the embedded fiberglass strands in this filament tape prevent that failure mode under tension, making it the preferred wrapping and securing material wherever the tape must hold under mechanical stress rather than just stick flat.
The filament tape 50mm wide format measured at 48mm actual width covers a larger surface area per wrap pass than the 25mm variant. On large-format battery packs of multiple 18650 cells, one pass of the 48mm tape spans the full cell diameter and more of the adjacent nickel strip, securing the pack structure with fewer total wrap turns. The cross filament tape strong pressure sensitive adhesive bonds to cell shrink wrap, PVC sleeve, cardboard and plastic surfaces on contact without requiring heat activation or solvent primer.
The insulation filament tape electrical insulating backing provides isolation between battery layers in pack, where the tape contacts exposed nickel strip or cell terminals between wrap turns. The 50mm filament tape roll wider format also suits industrial carton strapping, wire harness bundling on larger cable diameters and surface mount reinforcement on rigid enclosure. The 50 meter filament tape suits batch battery pack production and large cable management. This tape is working on battery pack construction and large scale wire management. Available on StemVolt.
