RD250 is the PTFE composite reinforced with woven fiberglass cloth with low dielectric constant,very low Loss Tangent, and low cost,etc. The RD250 uses a unique chemical formulation structure and process to improve the dielectric and mechanical properties of the material while reducing costs, and providing microwave RF designers with high frequency microwave materials of superior performance. Compared with existing domestic and foreign similar products and other traditional fluororesin glass cloth materials, RD250 has significant cost performance advantages.

RD250 has low dielectic loss and low PIM and other key features including low water absorption, lowest temperature drift coefficient TCEr (-153ppm/°C) and very low x, y, z axis expansion coefficients (14, 21 and 173ppm/°C), high copper foil peel strength and size and thermal stability. Its dielectric constant of 2.50 and smaller dielectric constant tolerance range (±0.05) can achieve high antenna efficiency and greater bandwidth,  also can be used to design miniaturized antennas, and save space for products.

RD250 can follow the standard PTFE circuit board processing process.
