Laminating Bulker is non-woven textile made from fine polyester fiber, manufactured in a continuous process similar to needlepunched felt. As the fiber is processed a 50% by volume load of hollow polyacrylonitrile microspheres is introduced along with an acrylic binder.
Perforations to facillitate faster resin saturation are hot needled into the Laminating Bulker as a final process before coiling and converting.

Why Can You Achieve Higher Mechanical Properties With Laminating Bulker?
3M Laminating Bulker
Most laminate bulkers available in the marketplace today are made of polyester fiber and glass microspheres. Only 3M Laminating Bulker has MULTI-DIRECTIONAL fiber orientation. Unlike the unidirectional fiber orientation used in bulker products manufactured by most of our competitors, our multi-directional fiber orientation provides equal strength characteristics in both length and width directions. It also helps in wetting out the laminate equally in both directions, as opposed to easier wet out in one direction in linear fiber products. LAMINATING BULKER PERFORMANCE CHARACTERISTICS INCLUDE:
3M Laminating Bulker is easily
recognized by its more frequent
perforations, which
help in the wetout of the
material and create more
vertical links as well as
easing the evacuation of
trapped air bubbles
throughout the laminate.
- Print blocking: Thinner-grade Laminating Bulker is a very effective print-through barrier when placed behind a skin coat.
- Screw retention: Laminating Bulker adds excellent screw retention capability to a laminate, and can be placed, for example, around the perimeter of swim platforms for rub rail installation.
- Microcracking prevention: Laminating Bulker reduces demolding cracks and stress cracks in gel coated parts.
Laminating Bulker performs at a level well above that of competitive products. Its shock resistance is 35 to 50 percent higher, one reason why products made with Matline obtain longer useful life cycles. Water absorption is equivalent to that of the competition. Its even, multi-directional fiber distribution offers reinforcement characteristics not available in competitive products.
The results of tests performed by certified labs in Europe and North America on products made by our principal competitors demonstrate that Matline exhibits superior impact and shear strength, thanks to stronger links between the different layers within the mat as well as excellent resin distribution throughout the product. Matline's excellent impact values underscore the ability of the Matline-reinforced laminate to meet toughness requirements and withstand severe-duty fatigue.
WEIGHT SAVINGS
Fabricators who use Matline
can realize as much as a 60
percent weight savings compared
to bulking laminate
with fiberglass. One layer of
Matline 301 replaces three
layers of 1.5-oz chopped
strand mat.
