据英国《增强塑料》1994年2、5、6期报道,目前由于有的马来酐(顺丁烯二酸酐)生产设备检修、停产,同时世界主要地区对它的需求增大,因此,出现了全球性马来酐供应紧张、价格上扬的局面。 美国近几年对马来酐的需求逐年递增,价格随之上涨。1994年4月1日熔化的和粉末的马来酐都涨到3美分/磅。 西欧近几年UP(不饱和聚酯树脂)供过于求,产量下降,如:1992年UP产量为41万t,年增长—7.7％;1993年37万t,年增长—
According to the British “Strengthening Plastics” report of the second, fifth and sixth periods of 1994, at present, due to the overhaul and discontinuation of some maleic anhydride (maleic anhydride) production equipment, the demand in the major regions of the world has increased. The global supply of maleic anhydride is tight and prices are rising. In the United States, the demand for maleic anhydride in recent years has been increasing year by year and prices have risen. Melting and powdered maleic anhydride rose to 3 cents per pound on April 1, 1994. In Western Europe, oversupply of UP (Unsaturated Polyester Resin) has declined in recent years and production has declined. For example, in 1992, UP production was 410,000 tons, an annual increase of -7.7%; in 1993, it was 370,000 tons, an annual increase -
