    The scoop on global TiO2

    01 March 2002

    The bulk TiO2 pigment market of late has been characterised by consolidation, capacity increments, and cost reduction. Above all, a very weak market hit 2001 and producers are still suffering, being tightly squeezed as they are between feedstock suppliers and end users. Emergence from the doldrums seems to hinge on acceptance by consumers of a price increase, cutting of inventories, reduction in capacity, and a general positive swing in the world economies – not much then! However, the latter is not expected to kick in until the second half of 2002 or even early 2003 at best. It could be a long, tough old ride.

  • A coat for any occasion - Paper coating grade kaolin

    01 March 2002

    Paper coating grade kaolin (CGK) development can be discussed in terms of three generations of product characteristics: first generation with steep particle size distributions to impart brightness, gloss and print gloss; second generation products similar to first generation but modified to boost specific coated surface properties, enhance printability and/or lower coating costs; and third generation which are functionally engineered pigments, chemically modified to provide distinct functionality ie. for ink-jet printing.

  • Trends in papermaking - Pigment demand outstrips paper

    01 March 2002

    Total world paper and board production in 2000 was 323m. tonnes, and demand has grown from 2% to 3% per annum. This paper focuses on development trends in mineral usage in printing papers, which represent around 40% of the total paper and board production. With total pigment usage in the paper industry at approximately 27m. tpa, printing papers are the largest users of pigments, as fillers and coatings.

  • Fuelling chemical innovation - Chinese fluorspar to Japan

    01 March 2002

    Japan has long been at the forefront in the development of innovative fluorine chemistry, and is a major producer of hydrofluoric acid, the starting point for virtually all fluorochemicals made using acidspar. Japan is also a major steel producer and requires metspar in significant quantities. Having no major deposits of its own, Japan’s metspar requirements are imported from China and Mexico, and acidspar solely from China. This feature focuses on acidspar and the structure and fortunes of Japan’s fluorochemical industry.
