Resins Reinforce Materials
Resins are a catalyzed epoxy polymer used to impregnate the reinforcement to make a stronger and lighter material.
General Plastics & Composites utilizes many different resin systems and cloth/roving combinations to meet each part or assembly’s mechanical loading and environmental requirements. Material strength depends on manufacturing method, and reinforcement cloth weave / roving size and orientation. Our Materials Science department develops custom resin systems utilized with proprietary materials. Our engineers and technicians will work jointly with you to choose the best composite materials and manufacturing methods for construction.
