Increased DCB concentrations in TDI deliveries from BASF

According to BASF, BASF has identified quality differences in toluene diisocyanate (TDI) production in Ludwigshafen. TDI deliveries produced between 25 August and 29 September 2017 contain a significantly increased concentration of dichlorobenzene (DCB), according to the company.

In the meantime, the production process has been adapted in order to prevent further quality fluctuations. BASF had stopped the delivery of the corresponding product and informed its customers. The following measures were taken according to BASF:

    BASF will, at its expense, reduce TDI, which is still in the customer’s tank and has not yet been processed. This process is expected to be completed by the end of next week.     In addition, the company offers to collect all unprocessed foam blocks produced with the product from the corresponding period at BASF costs.     

For further processed product quantities, BASF recommends that customers perform tests as precautions to ensure that the relevant limits of the various industries are met.     BASF is in close contact with its customers and, if necessary, offers support in testing and consulting.

A customer hotline is currently set up. DCB is an organic compound. The colorless liquid is toxic to aquatic organisms with long-term effects. Dichlorobenzene can irritate skin, respiratory tract and eyes and is suspected of causing cancer.
