Rhein Chemie Additives has opened a production line for Rhenoshape tyre curing bladders at its Chinese production site in Qingdao. The Lanxess business unit set up the facility with a “low single-digit million euro” investment and initially the new production line will expand Rhein Chemie Additives’ global production capacity by around ten per cent. The operation in Qingdao is the company’s fourth bladder plant.
