1/4" and 1/2" Strand Fiber Filler
Chopped strand are E-Glass fibers that have been chopped into
1/4" (0.25") or 1/2" (0.50") lengths. They are easily
handled and added to a polyester or urethane resin system to
For polyester systems, chopped strand can be used to strengthen
edges or corners. Impact, tensile, compressive and flexural can
be increased through the addition of chopped strand.
Cabosil or fiberglass flock should be added as a thickening
agent to the system in order to prevent running of the liquid
APPLICATIONS: In addition to being used as a resin filler in
polyester, many of our clients have been successful using this
product to impart strength in urethane systems. Because the
chopped strand fibers will float, it is best to use fillite in
the system to thicken the liquid and prevent fiber floatation.
It is not recommended to use cabosil as a thickening agent in
urethane, as it is an easy way for moisture to enter the system
and cause unwanted air bubbles.
Chopped strand is also added to increase the strength of
plaster. In the production of plaster mother molds or cast
figures, the inherent brittle nature of plaster can be avoided
by adding chopped E glass fibers for strength.
