Different types of plastics can be bonded using a variety of adhesives and tapes. This depends on the type of plastic and the substrate to which it is being bonded.
The bond can be achieved by using adhesives – chemical substances that bond through the evaporation of a solvent or by curing using heat, pressure or time.
Although the type of surface is often considered the most important factor affecting adhesive bond strength, modern, advanced tapes and adhesives are capable of achieving the required properties on most surfaces without any special preparation.
Contemporary solutions are also suitable for bonding and repairing composite materials, such as CFRP/GFRP.
Typical applications of adhesives for plastics.
Bonding is essential in many manufacturing processes, for example in the automotive industry, plastics processing, construction, mechanical engineering, the packaging industry and medical technology. In these contexts, bonding not only replaces welding, riveting and screwing, but also enables new ways of joining materials. This is particularly useful when, for example, screws and rivets weaken a composite, or when welding and soldering introduce too much heat into the material.
At the same time, bonding techniques can be used to impart properties to a product that go beyond mere joining, such as insulation or electrical or thermal conductivity, sealing against gases and liquids, vibration damping, corrosion protection and compensation for relative movement between joined components.
