Tornesch/Germany, September 2022 – Regarding processability and performance characteristics, these materials are potential alternatives to conventional plastics based on fossil raw materials. An additional contribution to sustainability can be provided when the material usage is reduced by foaming.
In Green Polymers, which are made from renewable monomers instead of the fossil-based ones (e.g. Bio-PE, Bio-PP etc.), conventional TRACEL® foaming agent systems can be used. If necessary, the carrier polymer might be adapted as well. Endothermic TRACEL® products are physiologically harmless and generally also suitable for food contact applications.
Other Bio-Plastics, e.g. polyester-based, require adapted foaming agent systems, particularly special endothermic foaming agents. These are available on various bio-plastic carrier materials from TRAMACO.
The new TRACEL® grades are suitable for injection moulding and extrusion.
