RO4003C is a patented material reinforced with woven glass cloth in a hydrocarbon resin system/ceramic filler. Its electrical properties are very similar to PTFE/woven glass cloth materials, and its processability is similar to epoxy resin/glass cloth materials.

RO4350B can adopt standard processing technology of epoxy resin/glass cloth, while providing strictly controlled dielectric constant and loss, and its price is a fraction of traditional microwave materials. There is even no need for special through-hole pre-treatment or operation procedures like PTFE based microwave materials. At the same time, it has passed the UL 94V-0 fire rating required for active equipment and high-voltage RF design.
