Avient’s reinforced composite technologies use carbon, glass and aramid fibers with custom formulated thermoset or thermoplastic resins in continuous forming processes Composite Ballistic Panels for Use in Building and Construction Polystrand™ Continuous Fiber Reinforced Sandwich Panels

In 1997, the Frog Legs team developed an innovative alternative to the rigid casters commonly used for the front wheels. Their pursuit led them to carbon fiber composites and, subsequently, to Avient, a leading supplier of long fiber-reinforced thermoplastics and technologies. Using PlastiComp™ Complēt™ carbon fiber composites offered remarkable design flexibility.

These monomers are then polymerized into chains called polymers, or plastic resin, such as polyethylene and polypropylene, in their most basic forms. The major types of thermoplastics include polyethylene, polypropylene, polystyrene, polyester and a range of specialized engineering resins.
