Hotmelts are anhydrous and solvent-free adhesives composted of a mixture of thermoplastic materials. They are inexpensive and can be processed at very high machine speeds.
The most common base polymer is EVA, but this product line also includes adhesives based on APAO, PE, polyester and polyamide.
The book manufacturing business primarily uses EVA-based hotmelts. For perfect binding, Planatol offers a complete range of products with different qualities and a medium open time. Hotmelts with a longer open time are required for lateral glue applications.
Any of the types of hotmelts previously mentioned may be used in the packaging industry and for special applications.
Polyurethane thermoplastic adhesives (PUR) play a special role in the area of hotmelts. These adhesives provide a fast setting time (crystallisation) during processing, followed by a slow chemical reaction with humidity in the environment.
