Technical Information
  THE PULTRUSION PROCESS
The pultruded structural component is made by reinforcing a polymer resin (usually polyester or vinyl ester resin) with multiple strands of glass filament and alternating layers of glass mat.
The glass is drawn through the liquid resin, which coats and saturates the fibers.The combination of resin and glass is then continuously guided and pulled (pultruded) through a heated die that determines the shape of the component.
In the die, the resin is cured to form a permanent, rein- forced part which can be cut to a specific length. Since the hardened fiberglass pultrusion is reinforced with an inter- nal arrangement of permanently bonded continuous glass fibers, it possesses great strength. In addition to strength, pultruded fiberglass components exhibit exceptional corrosion resistance.This attribute makes fiberglass the material of choice for many harsh industrial applications.
RESIN SYSTEMS
Polyester and vinyl ester resin systems are available.The vinyl ester resin system is somewhat stronger and is applied in severe corrosive applications.
Both resin systems are flame retardant, conforming to ASTM E84, Class 1 flame rating and are self extinguishing per the requirements of UL94V-0.
Consult the corrosion resistance guide on page 8 and 9 to determine the correct resin system for your application.
