Plasma4Bio2K - Innovative plasma technology for adhesion- and property-optimised two-component injection moulding of bio-based and sustainable plastics
The ‘Plasma4Bio2K’ research project aims to develop products for oral hygiene, such as a toothbrush or toothbrush head, made from bio-based materials.
The aim is to offer environmentally friendly alternatives to conventional fossil-based plastics such as PP, PET, PE and PA. Instead, bio-based plastics made from renewable raw materials such as castor oil, sugar cane, maize or cellulose are to be used and three different models with different combinations of Bio-PP, Bio-PET, Bio-TPE and Bio-PE are to be developed.
As the adhesion of various bio-based plastics is challenging, environmentally friendly atmospheric pressure plasma technology is used instead of wet-chemical pre-treatment processes. It enables precise surface modification for better bonding properties and efficient application in the injection moulding process.
Plasmas are increasingly being used in the plastics sector, although their use in the injection moulding of bio-based plastics is still unexplored.
As part of the project, a material and action library for 2K injection moulding with bio-based plastics is to be created, which will allow production parameters to be optimised and plasma technology to be integrated into automated manufacturing processes. This will make a significant contribution to promoting bio-based plastics and supporting the bioeconomy.
