STYROSUN® - A Weather Resistant High Impact Polystyrene Specialty   STYROSUN® resins are weatherable, high-impact, styrenic polymers specifically designed for use in outdoor applications. Resistant to sunlight, STYROSUN® resins maintain significant physical properties after weathering. The weather resistant properties of STYROSUN® resins are achieved by combining proprietary UV-stabilization technology with an inherently UV-stable impact modifier.   The key advantage of STYROSUN® resins is the retention of physical properties after outdoor weathering and its very low dielectric loss factor (Telecommunication devices). Applications using STYROSUN® resins maintain functional product life and toughness after UV exposure.
