2018年全球聚甲醛樹脂消費量約為130萬噸，而2010年為80萬噸，2010-2018年年均增長6.4%。聚甲醛在小零件中的多功能性和實用性在很大程度上決定了終端用途的需求量。電氣電子（E/E）和電器是聚甲醛的主要終端應(yīng)用，約占33%。第二大終端應(yīng)用是交通運輸，占23%。其次是消費品（20%）和工業(yè)/機械（14%）。預(yù)計2018-2023年全球聚甲醛需求年均增速約為3.0％，主要推動因素是電子、消費品和制造業(yè)。未來，電子電氣和電器仍將是zui大的終端應(yīng)用。聚甲醛在聚甲醛中加入抗氧劑及光穩(wěn)定劑可以提高聚甲醛的耐候性。</p><div
