On 2 March 2010, BASF (Ludwigshafen / Germany; www.basf.com) reported limited availability of compounded PA 6.6 grades, specifically Ultramid A, Ultramid C and selected grades of the Capron and Miramid families. The group said the shortage was caused by an ongoing tight feedstock situation, carried over from last year, coupled with livelier demand.
BASF blamed insufficient supply of the feedstocks butadiene and ADN for the shortage, which it believes will be in place until June 2010. After announcing in mid-2009 that it intends to begin PA 6.6 production, Invista (Wichita, Kansas / USA; www.invista.com) still has not lifted force majeure (FM) for ADN. Butadiene remains tight as well, with BASF reporting FM for the feedstock in the US.
