When WACKER’s Robert Tangelder first approached the European carpet market, he’d had no prior contact with producers in this industry. Yet Tangelder found Edel extremely receptive right from the start. “Edel is a company that understands a great deal about chemistry and its work is very much based around finding solutions,” he says. “That is why they understood the special characteristics of VAE so fast and adapted them to their own processes.”
Initially, Dr. Mike de Lange certainly had his doubts. When he used SBL and VAE in parallel, the inherent differences in the flow propertiesof the two binders became apparent. So, the VAE formulation had to be customized. “Wow, we’re really charting unknown territory,” de Lange thought at times. Once the formulation had been optimized and following six months of intensive carpet testing, Edel was ready to change its technology. “From the moment we switched production entirely over to VAE, everything was fine,” he recalls, adding that, today, the in-factory processes were more stable and uniform with VAE than in the past, and didn’t have to be modified as often. “So, the production staff also see the positive effects of VAE during processing,” says de Lange.
