POM用在那些對潤滑性、耐磨損性、剛性和尺寸穩定性要求比較嚴格的滑動和滾動的機械部件上，性能尤為優越，因此主要用于工業機械、汽車、電子電氣、管件和灌溉用品等方面。中國pom市場增長迅速，2002年中國pom市場表觀消費量為13.657萬噸，1990～2002年pom市場表觀消費量年均增長率為11.7%。預計2005年中國pom市場表觀消費量為16.8萬噸，2000～2005年pom市場表觀消費量年均增長率將達到10.3%。到2010年，中國pom市場表觀消費量將增加到19.7萬噸，2005～2010年pom市場表觀消費量年均增長率將達到3.2%。

“Solar thermal power plants concentrate sunlight to produce high temperatures. In sunny regions, they are thus able to deliver large of environment-friendly electricity from a renewable source,” explains Professor Robert Pitz-Paal, Director of the Institute of Solar Research at the German Aerospace Center (DLR). Concentrating solar power (CSP) is best suited to countries with high sun intensity. The Moroccan solar park is in a perfect location: in the area around Ouarzazate, solar radiation reaches an intensity of more than 2,500 kilowatt-hours (kWh) per square meter per year, one of the highest levels in the world.
