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.
