Bioadhesives on an Industrial Scale

The demand for products that do not require fossil raw materials has risen sharply in recent years. The "BioPSA" joint project therefore focused on the further development of hotmelt pressure-sensitive adhesives made from renewable raw materials that can also be produced on a large scale.

Pressure-sensitive adhesives (PSAs) are characterized by the fact that they remain permanently tacky at room temperature. A hotmelt pressure-sensitive adhesive is a pressure-sensitive adhesive that is processed from a melt. They are primarily comprised of three basic components: a primary polymeric ingredient, a tackifier, and a plasticizer and other additives. Primary polymeric ingredients - also known as base polymers - are responsible for the cohesiveness of the entire formulation and for the adhesion.
