West System 727 Fibreglass Tape - Biaxial 125mm x 5m

Versatile glass tapes are ideal for reinforcing chines, hull/deck joints and similar structural applications. When bonded with West System epoxy, they provide added tensile strength to resist hairline crack development and add added abrasion resistance.

WEST SYSTEM BIAXIAL TAPE

727 Biaxial Tape is 15 oz (per square yard) electrical grade fiberglass referred to as E glass. Biaxial is essentially two layers of unidirectional fiberglass placed 45° to the ‘0’ axis off the roll. The layers are held together with a light stitching, thus it is referred to as a stitched tape. It should not be confused with braid, which is woven. Biaxial has good utility as the strands are oriented to allow the tape to pass over a tighter corner. Biaxial is generally stronger on a per thickness basis than a woven fabric. 727 is .018" per tow in thickness and has a specific gravity of 2.54. Woven tape has half its fibers taking the full brunt of the bend whereas with biaxial they pass as a more gradual 45° angle. However, Biaxial materials will take more filling with resin or fillers to finish smooth.
