Polyurethane: From Old to New

Dear Readers,

in order to promote the circular economy, cooperation along the value chain is often invoked. Four major players in the plastics industry have now entered into such a cooperation to recycle polyurethane foams.

Up to now, these foams have largely been thermally recycled. The aim of the companies is now to process them chemically instead and to use the polyol obtained again for the production of polyurethane.

Enjoy reading!

Citro?n and BASF Unveil Electric Concept Car Oli

The high functionality of the concept vehicle should even allow users to stand on the hood and roof. ? BASF/Citro?n

The 雪铁龙 oli (all-?) is intended to stand for sustainable mobility. The flat hood, roof and rear cargo area were developed to ensure low weight, high strength as well as maximum durability – thanks to materials from 巴斯夫 . Read more

Additive Manufactured Mold Cavity Increases Production Efficiency

In the center of the image, the two halves of the injection molding tool can be seen. The inner cavities were created by additive manufacturing. The contributors from left to right are: Nicolas Büttner, Dominik Lawatsch, Dr. Sebastian Neubauer (all Valeo), Christian Hellmuth, Michael Vosswinkel (both Hofmann). Pawel Uchyla (Valeo) is missing. ? Valeo/Hofmann

Based on simulations and prototype production, the influence of an additive manufactured injection molding tool cavity on the manufacturing process was investigated. Due to the improved cooling performance, the cycle time can be reduced by approximately 10 %, whereas at the same time, a high dimensional stability of the polybutylene terephthalate (PBT) component can be achieved.
