Plastics: Pultrusions / Fiberglass Composites
Our Pultrusion partner pultrudes fiber reinforced resin composite products and custom shapes utilizing the unique pultrusion process.
PULTRUSION PROFILES INCLUDE
SOLID RODS: 0.080” O.D. through 2” O.D.
TUBING: ½” O.D. through 4.60” O.D.
The pultrusion process is a very efficient way to manufacture fiber-reinforced composite products. It allows the production of continuous lengths of fiber-reinforced polymer (FRP) profile shapes. The “pulling” process permits the strategic placement of continuous strand glass fiber, allowing for the optimization of structural properties.
FRP pultruded structural shapes have a superior long-term resistance to chemical corrosion and environmental weathering. Pultrusions have great strength due to multidirectional reinforcement.
Resin types include polyester, vinyl ester, polyurethane, & epoxy. The combination of resin & fiberglass is pulled through a special heated & shaped die (in a process called polymerization) using a continuous “puller” device.
The material then hardens to conform to the shape of the die and is heat-set into a permanent and rigid structurally reinforce shape. The protruded profile is then cut to the required length.
