Weldable Material for High Frequency/Radio Frequency Welding Machine(HF/RF welder)

High frequency welding machine, also called radio frequency welding machine, dielectric welding machine, and dielectric interface, and HF/RF welding, sealing machine, which is suitable for polymer material containing high dielectric constant in seam joints bonding, because of its internal heating caused from molecular random flip, friction to realign them original, pneumatic driven high frequency electrode bar applies pressure dispense high frequency energy to exert alternative electromagnetic in raising temperature of interval melting and solidifying, but, not all of plastic is weldable for high frequency machine, under lists is collected for reference in determining the suitable material when fabricate your flexible products
