727 Biaxial Tape is 4" wide, 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.
Comes in 2 pack sizes: 4" x 10' and 4" x 20 yards
