Tuned for Wireless — The Low-Dielectric Alloy Engineered for the 5G Era
Material Overview
PBT/ABS occupies a quiet but increasingly critical niche in modern electronics: the alloy of choice for housings that must transmit signals without distorting them. As wireless devices push into higher frequencies — 5G millimeter-wave, Wi-Fi 6/7, automotive radar, and IoT mesh networks — the dielectric properties of the housing material directly affect signal integrity.
Standard PC/ABS introduces too much dielectric loss; specialty fluoropolymers solve the problem but cost too much for mass production. PBT/ABS hits the engineering sweet spot — combining PBT’s lower dielectric constant with ABS’s smooth aesthetic surface, supported by improved chemical resistance and heat tolerance.
Key Features
📡 Low Dielectric Constant (Dk)
Specialty grades achieve Dk below 3.0 at 1 GHz — minimizing signal attenuation in wireless devices.
📐 Dimensional Stability
Low and isotropic shrinkage delivers tight-tolerance flat panels and connector housings.
🧪 Improved Chemical Resistance vs. ABS
PBT phase resists oils, solvents, and cleaners that compromise pure ABS.
🌡️ Higher Heat Resistance than PC/ABS
HDT up to 130°C in reinforced grades — enabling lead-free SMT compatibility.
✨ Aesthetic Surface
Retains ABS-quality surface finish, suitable for visible consumer electronics housings.
