Butt welding machines are suitable for most thermoplastic materials, which soften when heated and solidify when cooled.
The following are commonly used types of plastics suitable for hot melt welding:
Polyethylene (PE): Polyethylene is a common thermoplastic material used extensively in the manufacturing of plastic bags, bottles, containers, and pipes.
Polypropylene (PP): Polypropylene is another widely used thermoplastic material suitable for automotive components, electronic devices, medical instruments, and more.
Polyvinyl Chloride (PVC): PVC exhibits excellent chemical resistance and heat resistance, making it applicable in construction, wire and cable, pipe manufacturing, and other industries.
Polystyrene (PS): Polystyrene is commonly used in packaging, insulation cups, household appliance casings, and other manufacturing applications.
Polycarbonate (PC): Polycarbonate offers outstanding impact resistance and transparency, making it popular in the electronics, optical, and medical fields.
Which plastics are not suitable for hot melt welding?
Butt fusion welding is not suitable for thermosetting plastics, as these materials undergo irreversible curing after being heated and cannot be softened again. Common examples of thermosetting plastics include epoxy resins, phenolic resins, and unsaturated polyesters. Since thermosetting plastics cannot be re-softened, they cannot be joined using the hot melt welding method.
