The material most common in high frequency welding in PVC(Polyvinylchlorde) (something called simply vinyl) and PU(polyurethane) which are the most common thermoplastics that are wieldable by HF. also it is possbile to perform HF welding on other types of materia inculding naylon, PA, ABS, modified TOP, PETG, but particular attention should be pay on working parameters. HF welding is not suitable for PTFE, polycarbonte, polystyrne, polyethylene or polypropylene. However, a special type of mixed fabrics have been produced recently, which have the capability to be HF welded.The material can be thick or thin, reinforced or coated. It cab also be plain, coloured or structure/patterned.

         Observe that bonding requires the two materials to flow and mix easily. Thus PVC materials can be welded with PVC components and PUR sheets needs special PUR components.

        There are many other materials which can be welded by High Frequency but generally they will have a laminate of some type of polymer to allow the High Frequency to work. The main materials used in packaging are:PVC, EVA, PEVA, PET, PETG, TPU, TPR, PU, MPE, PE, and paste the above synthetic material coating or welding or bonding of textile materials.
