Material Requirements for 5G Communication Equipment

5G communication equipment has special requirements for materials, mainly including:
Low Dielectric Properties: Low dielectric constant (Dk) and low dissipation factor (Df) are required to reduce signal loss. Ideally, the Df value should be below 0.003 at 10GHz.

Temperature Resistance: A wide operating temperature range is required, capable of adapting to environments from -40℃ to +125℃.
Electrical Insulation: Excellent insulation properties ensure signal transmission stability.
Chemical Stability: Maintaining stable performance in complex environments.
Mechanical Properties: Good flexibility and shear resistance.
