ruilong rd255 is a polytetrafluoroethylene (ptfe) composite reinforced with woven glass fiber cloth, with low dielectric constant, excellent dielectric loss and low cost. rd255 adopts the unique chemical formula structure and process, improves the dielectric and mechanical properties of the material, and provides the high frequency microwave material with better performance for the microwave rf designers.

dragon media rd255 have low to dielectric loss angle and low pim, and other major features include low water absorbability, the lowest level of temperature drift coefficient of tcer (153 ppm / ℃) and very low x, y, z axis expansion coefficient (14, 21 and 173 ppm / ℃), the copper foil with high peel strength and size and thermal stability, and its dielectric constant is 2.55 and the smaller the dielectric constant of tolerance range ( / - 0.04) can obtain high antenna efficiency, and greater bandwidth, and can also be used to design miniaturized antenna, save a space for the product.

ruilong rd255 can follow the processing process of standard ptfe circuit board.
