Wangling TP Series Substrate Overview

Wangling TP series represents a unique high-frequency thermoplastic substrate lineup in the industry, adopting a specialized composite formula of polyphenylene oxide resin and nano-ceramic fillers without any fiberglass reinforcement. Different from traditional fiberglass-reinforced high-frequency laminates, its dielectric constant can be precisely calibrated by adjusting the mixing ratio of ceramic particles and PPO resin, achieving customizable dielectric parameters for diverse high-frequency scenarios. The series features graded structural classification: pure dielectric substrates are defined as TP, single-sided copper-clad variants as TP-1, and double-sided copper-clad versions as TP-2. With exclusive molding and lamination techniques, TP series substrates deliver exceptional electrical consistency, extreme environmental resistance and superior structural machinability, serving as a high-reliability alternative for precision microwave and antenna hardware.
