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.
