While the recycling of thermoplastic materials has been used in practice for decades, the recycling of PTFE was previously considered unfeasible. The reason for this is the processing of PTFE in the press-sintering process, as plasticising the materials is not possible due to the high molecular weight. In the press-sintering process, the smallest grain sizes are required (d₅₀ < 50 mm) in order to compact the material sufficiently and to achieve the target properties. STASSKOL has been working on the recycling of these materials for about 10 years and has now developed a process to successfully recycle PTFE. For this purpose, waste that accumulates in the form of chips during the manufacture of the products is collected by type and crushed and ground in a 2-step process. The resulting powder can be mixed into the virgin material and fed back into the product cycle. A positive side effect: the mechanical and tribological properties of the PTFE with recyclate content are even improved by the double heat treatment compared to the pure virgin material. The recycling of PFAS materials is an important step towards relieving the environment and reducing the consumption of resources.
