Avient Thermoplastic Tapes Engineered or unidirectional fibers are combined with thermoplastic resins to create continuous fiber-reinforced composite materials that provide superior strength-to-weight ratio and high performance for reinforcement across a broad range of applications. POLYSTRAND™ THERMOPLASTIC TAPES STRONG, IMPACT RESISTANT, LIGHTWEIGHT Formulated with glass fiber reinforcement and engineered thermoplastic resins, these continuous fiber composites offer reduced weight while maintaining exceptional strength and impact resistance. FIBER-LINE™ THERMOPLASTIC TAPES STRONG, CREEP RESISTANT, CHEMICAL RESISTANT Fiber-Line Specialty Engineered Thermoplastic Tapes are formulations composed of a wide range of fibers that are uniquely engineered to enhance fiber performance—such as twisting and coating— and then custom manufactured into a composite tape with a thermoplastic resin.
