Ability to post-form

• Tight batch-to-batch tolerance • Wide Dk range from 2.6 up to 23 • Lower weight and better impact resistance than ceramics • Isotropic material suits well for narrow beam widths (less than 0.2°) • Injection molding for complex shapes • Low cost mass manufacturing Whether we are talking about portable satellite terminals or stationary land stations, the material requirements are alike: reliable, low loss materials with low manufacturing costs, light weight and the ability to form complex shapes. Feasible form factors can be obtained even below 1 GHz with high permittivity materials.

By 2030, Avient will reduce Scope 1 & 2 greenhouse gas (GHG) emissions by 60% with 2019 as a baseline and achieve operational carbon neutrality by 2050. Deferred compensation, whether in the form of cash or common shares, is held in trust for the participating Directors.

Entanglement of longer fiber filaments allows the long fiber part to retain its molded form, which provides more structural integrity and increased toughness. During injection molding, longer fibers align and intertwine to form an internal skeletal network, enabling a unique set of performance characteristics, including: • High strength-to-weight ratio which facilitates metal replacement to achieve weight reduction • Added stiffness and strength to carry loads while resisting creep deformation • Increased toughness to absorb impact forces without permanent damage • High cyclical fatigue endurance to resist cracking and crack propagation • Mechanical performance that is retained across a wide temperature range • Improved dimensional stability with nearly isotropic properties and low thermal expansion • Corrosion and chemical resistance Long fiber composites provide a combination of stiffness, strength, and toughness performance enhancements not available together when using other reinforcing methods, while retaining the single- step processing simplicity of injection molding. DESIGN & DEPLOY WITH CONFIDENCE Transitioning from traditional materials to long fiber composites requires an integrated approach that includes material formulation, component design, and forming process.
