The compounding process provides the basis for the development of new plastic materials with advanced or enhanced properties. These properties can include mechanical, thermal, rheological, aesthetic and advanced characteristics.

At AIMPLAS, we provide materials with advanced properties, such as increased impact resistance, compatibilization of bioplastics (e.g. PLA, PBAT, PHB), improved fluidity, reduced odour in recycled plastics, electrical and thermal conductivity, antimicrobial resistance and fire resistance.
