Fraunhofer Institute for Structural Durability and System Reliability LBF, Germany, with support from the German Federation of Industrial Research Associations (AiF) and pinfa, launched a project to demonstrate the recyclability of several thermoplastics formulations using PIN flame retardants.
They will test polypropylene, PC/ABS, polyamides (PA-6 and PA-6.6), and polyethylenes, using phosphorus, nitrogen and mineral based PIN flame retardants provided by pinfa member companies Adeka, BASF, Budenheim, Clariant, Nabaltec. The project also involves compounders and recyclers Material quality after multiple extrusion and after accelerated ageing will be studied, as well as maintenance of fire performance (UL-94) and mechanical properties, polymer and additive degradation and potential for reformulation (re-stabilisation, compatibility). The project was approved by AiF in October 2015, and will run to the end of 2017.
