Caremelt® - the bio-based and biodegradable adhesive

Caremelt stands for hotmelt adhesives based on biobased and/or biodegradable polymers. The polymers are partly modified chemically and/or by additives so that they can be used as base polymers for hotmelt adhesives. A selection of commercially available bioplastics is the basis for various types of caremelt.

These include:

  • Polylactide (PLA)
  • Polybutylene succinate (PBS)
  • Polybutylene adipate terephthalate (PBAT)
  • Polycaprolactone (PCL)
  • Polyhydroxybutyrate (PHB)

Bio-resins based on rosin and terpenes, as well as bio-based plasticizers and waxes are used for the formulation into ready-to-use hotmelt adhesives. Thus, formulations with different properties can be created:

  • Viscosity (140°C): 5,000 - 30,000 mPas
  • Softening point (R&K): 75 - 115°C
  • Thermal stability (S.A.F.T.): 50 - 105°C

After thorough testing, Caremelt has already been named a promising hotmelt adhesive by renowned adhesive manufacturers. The range of applications extends from the packaging industry to bookbinding and from the wood and furniture industry to the do-it-yourself sector. In addition to the classic application, however, hotmelt adhesives can also be modified in the form of films, nonwovens or powders for the textile and automotive sectors.
