Mat Tape

Tear Apart and Reinforce Tough Spots

Mat Tape Overview

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.

 

What is Mat Tape?

Mat Tape (#492) from Fibre Glast is a 1.5 oz/sq ft chopped strand mat tape, 4" wide and 0.045" thick, ideally suited to reinforce the seams, corners, or edges of larger parts made from chopped strand mat or other fiberglass fabrics.
 

Why Choose Mat Tape?

Mat Tape provides the same rapid-wetting, high-conformability characteristics of full-width chopped strand mat (#250/#1250) in a convenient 4-inch-wide tape format. This narrow width makes it ideal for targeted reinforcement at seams and joints where a full sheet of mat would be wasteful and difficult to position.

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.
 
Chopped strand mat is most frequently used with polyester resin to quickly build thickness for parts and between layers of fabric for building molds. Mat can be used alone or in conjunction with fiberglass fabrics, or woven roving, in larger fabrications. 

 What Are the Best Applications for Mat Tape?

Reinforcing seams, corners, or edges of larger fiberglass parts. Building up joints where separate molded pieces meet. For applications requiring a wider format, use Chopped Strand Mat in 38" (#250) and 50" (#1250) widths.
 

How Should Mat Tape Be Used for Best Results?

Mat Tape is not adhesive backed. It contains a binder that holds it together and prevents proper bonding with any epoxy resins. ONLY compatible with polyester or vinyl ester resins. Tear apart rather than cut for stronger bonds at edges. Features quick wetting and rapid air release for maximum molding productivity and reduced cost, excellent weight uniformity for consistent part quality, and superb dry mat integrity for reduced material losses during cutting and piece handling.
 
 Available in 10-yard roll (#492-C) and 86-yard roll (#492-D).

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.
