1.EVA foam bonding: EVA foam, also known as EVA foaming, is a sponge composed of vinyl acetate and has good resilience. When bonding EVA foam, it is recommended to use EVA hot melt adhesive film, because EVA hot melt adhesive has similar properties to EVA material and has better adhesion. EVA hot melt adhesive film is not only highly viscous, but also has strong water resistance and dry cleaning resistance.
2.Conductive foam bonding: In the electronics industry, conductive foam or conductive pad is a gap shielding material that is light, compressible and conductive. A layer of hot melt adhesive film can be attached between the conductive cloth and the conductive foam to bond the conductive cloth and the conductive foam into an integrated structure, reduce the contact resistance value, and provide a good electromagnetic shielding effect.
3.PES hot melt adhesive film: In the field of electronic shielding materials, PES hot melt adhesive film is often used for the composite of foam and conductive cloth. This kind of film has high requirements for thickness, usually thinner products are used, and the thickness accuracy of the film must be well controlled. Sometimes it also needs to have a certain flame retardant function.
4.TPU hot melt adhesive film: In the composite of electronic product protective covers, high-end electronic product protective covers may involve the composite bonding of leather and plastic. At this time, TPU hot melt adhesive film is often used for bonding, which has a better bonding effect on genuine leather, PU leather, and various plastic materials.
5.Flame retardant hot melt adhesive film: For foam bonding that requires flame retardant function, you can choose flame retardant series hot melt adhesive film products, such as HD200 and HD200E, which have good bonding properties, flame retardant properties, halogen-free and environmentally friendly properties.
In summary, hot melt adhesive film is an effective material for bonding foam. According to different foam types and application requirements, you can choose EVA hot melt adhesive film, PES hot melt adhesive film, TPU hot melt adhesive film or flame retardant hot melt adhesive film, etc.
