PREPERM™ thermoplastics are an excellent choice for mmWave radomes due to the​ low dielectric constant and ultra-low losses. Other benefits include high levels of isotropy, low water absorption, and excellent mechanical properties, even in arctic conditions Low and stable εr • Ultra-low loss • Low water absorption • Hydrolysis resistant • Excellent impact strength • Mass production friendly APPLICATION BULLETIN A PREPERM radome grade gives you a longer and wider scanning range compared to common resins. 40 m Comparison of PREPERM radome grade and common resin at 24 GHz and 79 GHz bands Common Resin Common Resin PREPERM™ RB260 PREPERM™ RB260 PARAMETER PBT+GF PEI PREPERM RADOME GRADE ELECTRICAL εr @ 77 GHz 3.5–4.2 3.1 2.6 Tan @ 77 GHz 0.03 0.003 0.003 Isotropic @ 77 GHz No Yes Yes MECHANICAL Impact strength -20°C/+23°C notched izod 6kJ/m2/6kJ/m2 6kJ/m2/6kJ/m2 25kJ/m2/35kJ/m2 Elongation @ break 3% 40% 22% Brittleness Yes Yes No THERMAL Max use temp (HDT) 200–220°C 190–200°C 150–180°C Inherent flammability HB V0 V1 to V0 ENVIRONMENTAL Water absorption 0.4% 1.25% 0.2% Chemical resistance Good Excellent Good Hydrolysis resistant Specific Grade Yes Yes MANUFACTURING Batch-to-batch consistency Limited Excellent Excellent Moldability Excellent Good Good Abrasive Yes No No Mold shrinkage Inconsistent, warpage issue Homogenous Homogenous Raw material price Low High Moderate Copyright © 2022, Avient Corporation.

The Nymax BIO portfolio includes six grades that offer lower warpage plus excellent surface appearance and colorability compared with traditional PA66 glass fiber-filled materials. Four of them are low water absorption grades that deliver excellent dimensional stability and property retention after conditioning, solving the problem of water influence on finished parts. KEY CHARACTERISTICS • Bio-polymers that reduce the carbon footprint value significantly • Achieves equivalent performance as PA66 glass fiber-filled materials • Excellent surface appearance and colorability • Lower warpage compared with PA66 glass fiber-filled materials • Cost-effective alternative to PA66 glass fiber-filled materials • Excellent dimensional stability and property retention rate after water uptake • Commercially available in Asia APPLICATIONS Nymax BIO formulations can be applied to reach sustainability goals in demanding applications including: • Transportation • Consumer goods • Industrial • Building and construction PRODUCT BULLETIN 1.844.4AVIENT www.avient.com Copyright © 2022, Avient Corporation.

These grades combine excellent chemical resistance and dimensional stability with improved wear resistance and low coefficient of friction (COF) properties. KEY CHARACTERISTICS • Inherently low COF • Excellent wear resistance • Excellent chemical resistance • Low moisture uptake • Excellent dimensional stability • Cost-effective • Eco-conscious alternative to PA66, PA6 and POM MARKETS & APPLICATIONS These materials are ideal for use in applications requiring lubricated solutions, as the formulations have improved wear, chemical, and hydrolysis resistance over nylons (PA6 or PA66).
