| Pultrusion is a continuous moulding process utilizing glass
or other fibrous reinforcement in a polyester or other resin
matrix. Pre-selected reinforcement materials like fibreglass
roving, matt or cloth, are drawn through a resin bath where
all the material is thoroughly impregnated with a liquid thermosetting
resin. The wet fibrous laminate is formed to the desired geometric
shape and pulled into a heated steel die. |
| Once in the die, setting of the resin is initiated by controlling
precise elevated temperatures. The laminate solidifies in
the exact shape of the cavity of the die as it is being continuously
pulled by the pultrusion machine. |

| A pultruded composite consists of reinforcing
materials, such as unidirectional glass fibers, other wise
called rovings, continuous fiberglass mat and a thermoset
resin that binds the composite together. A polyester surfacing
veil to improve the external appearance of the composite,
and chemical resistance or weatherability may also be added.
A variety of ancillary materials may be added to the resin
formulation, such as pigment for color, accelerators to speed
the curing of the thermoset resin, internal release agents,
and several various types of inert fillers, each having its
own functionality. A pultruded profile can be uniquely designed
to meet your custom application. |
