Tear Apart and Reinforce Tough Spots

1.5 oz/sq ft mat, 4" Wide, 0.045" Thick

Chopped Strand Mat Tape is ideally suited to reinforce the seams, corners, or edges of larger parts made from chopped strand mat or other fiberglass fabrics.

Fabricators generally tear apart this tape, rather than cut it. This maintains the length of fibers along the torn edge, which create stronger bonds with subsequent layers.

  • Quick wetting and rapid air release, which allows for maximum molding productivity and reduced cost.
  • Excellent weight uniformity allows consistent part quality.
  • Superb dry mat integrity enhances productivity and reduces material losses during cutting and piece handling.

Mat Tape is called tape only for its width and appearance. It is not adhesive backed. Like its fabric counterpart, it contains a binder that holds it together and prevents proper bonding with any epoxy resins. PLEASE NOTE: it is only compatible with polyester or vinyl ester resins.

For applications requiring a wider format, use Chopped Strand Mat in 38-inch (#250) and 50-inch (#1250) widths.


The 10 yd. roll (#492-C), when ordered alone, will typically ship in a small box. The 86 yd. roll (#492-D) will typically ship in a medium box. Where possible, we will combine ordered items to reduce the number of boxes shipped.


Mat Tape This tape is only available in two pre-cut lengths, one measuring ten yards (#492-C, roll), the other measuring 86 yards (#496-D, roll). Each is packaged and sold separately.

The 4 inch chopped mat tape is convenient to use, especially in the sculpture I'm working on. It does have a tendency to shed
fibers to a greater extent than the sheets, but that's a small price to pay for the ability to wrap tubular objects without the mess and delay cutting sections of mat while trying (and often failing) to keep the pieces even.. I'm quite pleased with it.
