Perstorp has a broad offering for different adhesives technologies. Our Capa™ Thermoplastics are formulated into Hot Melt adhesives whereas Capa™ Polyols are used in Liquid Polyurethane (PU) adhesives. 

Capa™ Thermoplastics are added when a performance enhancer is needed to produce Hot Melt adhesives with high demands. Capa™ plays a vital role in improving both the adhesion and bonding process.  Give Capa™ a sticky challenge, and it will rise to it. Capa™ Thermoplastics ensure you have no problem in getting excellent adhesion to a variety of substrates.  

Capa™ Thermoplastics have a low melting point and with its unique cooling properties allows for a long open time. The combination of early green strength and long opening time is a unique performance of Hot Melt adhesives based on Capa™. The early green strength enables quick and strong bonding that remains stable and flexible even in cold environments. They are highly compatible, allowing them to be processed effectively with other polymers and are also nontoxic in nature. The thermal stability of Capa™ with little or no changes in viscosity provides a good pot life. 

 Hot Melt adhesives are used typically on substrates such as fabrics, textiles, cardboard, leather and packaging material. For sensitive materials the low melting point will enable a good bonding even at low temperatures. Capa™ Thermoplastics can be utilized in conventional Hot Melt adhesives and Reactive Hot Melt adhesives.
