Dichlorobenzene Content Exceeded, BASF Recall Thousands of Tons TDI in Europe

BASF said it has recently found that the quality of TDI produced by Ludwigshafen has fluctuated. The TDI delivered at this site from August 25 to September 29, 2017 contains excess amounts of dichlorobenzene (DCB) , the reason is that there are technical defects in the productive process, which are now being excluded.

BASF has notified about 50 affected customers and stopped delivering this product. BASF confirmed that the affected materials were not sold directly to Asia. TDI production facilities in Asia have not been affected, and no similar quality problems have been found.

About two-thirds of the 7,500 tons TDI with excessive dichlorobenzene content has not yet been further processed and BASF is recalling  these products. For finished products, BASF is actively engaged with relevant customers, including a team of 75 experts who are helping customers to detect dichlorobenzene content and prevent any occurrence of any hazards. As a part of the risk assessment, BASF experts conducted a preliminary test of the TDI foam produced from August 25 to September 29 in Ludwigshafen of Germany. The results and subsequent calculations show that there is no health risks. BASF will provide detailed assessment information to the relevant authorities and associations.

BASF said it has taken the following measures: It is recalling unprocessed TDI and unprocessed foam blocks, which are expected to be recalled completely by the end of next week. For the processed products, BASF is assisting customers with the relevant tests to ensure that the products meet the specific requirements of different industries.

It is reported that dichlorobenzene is a colorless liquid organic compound,it has persistent toxicity to aquatic organisms if enters into the water. It can cause stimulate in skin, respiratory and eye irritation as well as allergy. There is a possibility of cancer.

TDI (tolylene diisocyanate) is an important raw materials for the manufacture of polyurethanes and is mainly used in the furniture industry such as elastic foam mattresses, mattresses or wood coatings as well as the automotive industry (car seat cushions).
