In addition, demand for composites including Dyneema applications for personal protection were also higher,” said Robert M. We bolstered our composites business with the acquisition of APM and divested our Distribution segment. We do expect conditions to improve in the second half of the year driven by performance in our key growth drivers, particularly sustainable solutions and composites.

Fiber-Line™ Specialty Engineered Thermoplastic Tapes PRODUCT BULLETIN Fiber-Line™ Specialty Engineered Thermoplastic Tapes are composite formulations composed of a wide range of fibers that are uniquely engineered to enhance fiber and composite tape performance— such as twisting and coating—and subsequently custom manufactured into a tape cured with a thermoplastic resin. Engineered fiber thermoplastic composite tapes provide excellent strength-to- weight performance and creep resistance suitable for demanding applications. KEY FEATURES • Compatible with various Fiber-Line fibers, performance-adding processes, and thermoplastic resins to meet your application needs • Tapes available up to 5" in width via spools or cut-to-length profiles • Rapid prototyping capability FIBERS • Carbon Fiber • Kevlar® Para-Aramid • Nomex® Meta-Aramid • Fiberglass PERFORMANCE-ADDING PROCESSES • Coating • Twisting KEY APPLICATIONS • Oil & Gas • Industrial • Aerospace • Composite applications needing unique/ specialized reinforcement Copyright © 2024, Avient Corporation.

Spring deflection limitations: The free movement or deflection of springs must be limited so that it does not overstress the composite. Exposure to finishing operations: One time exposure to elevated temperatures of up to 400°F (204°C) for 15 to 20 minutes, typical for the application of coatings, have no effect on the performance of the composite springs.
