About Composites

Arc-Resistant GPO3
Fiberglass Sheets and Strips

Offering excellent arc and track resistance, this GPO3 fiberglass is often used for electrical applications in humid environments.

Structural FRP Fiberglass
Sheets, Bars, and Strips

An alternative to wood in structural applications, FRP fiberglass is strong and lightweight.

High-Temperature FRP Fiberglass

With more than twice the heat tolerance of standard FRP fiberglass, this material withstands temperatures up to 370° F.

Flame-Retardant FRP
Fiberglass Sheets and Bars

Made with a flame-retardant resin, this FRP fiberglass meets ASTM E84 Class A.

Ultra-High-Temperature
High-Strength SG-200 Fiberglass

SG-200 fiberglass withstands temperatures up to 410° F—higher than any of our other fiberglass raw materials. It’s also stronger than FRP fiberglass and easy to machine.

Chemical-Resistant FRP Fiberglass

This FRP fiberglass is made with a chemical-resistant resin that stands up to harsh environments.

Composite Fiber Aramid
Honeycomb Panels

With an aramid honeycomb core sandwiched between carbon fiber or fiberglass for rigidity, these panels are strong, but lightweight, and won’t conduct heat. Often used as wall panels in structural and insulating applications, they’re a lightweight alternative to solid composite and aluminum honeycomb panels.
