顺丁烯二酸酐在玻璃钢工业中主要用作不饱和聚酯树脂（UPR）的原料；1,4-丁二醇（BDO）、四氢呋喃（THF）和γ-丁内酯（GBL）；还用于涂料、润滑油添加剂、农药、酒石酸、琥珀酸和酸酐、四氢苯酐、改性松香等不饱和聚酯树脂（UPR）：是热固性树脂的主要品种之一。
MALEIC anhydride are mainly used as raw materials for unsaturated polyester resin (UPR) , 1,4-Butanediol, oxolane and γ-butyrolactone (GBL) in the FRP industry; Also used in coatings, lubricant additives, pesticides, tartaric acid, succinic acid and anhydride, tetrahydrophthalic anhydride, modified Rosin and other unsaturated polyester resin (UPR) : is one of the main varieties of thermosetting resin.
它以其优异的机械性能、电气性能、耐化学腐蚀性和简单的加工工艺而被广泛应用。顺丁烯二酸酐制造商经营400多个的不饱和聚酯树脂，主要包括邻苯型、间苯型、对苯型、双酚a型等。顺酐生产厂家根据用途和功能，它们包括通用树脂、耐化学树脂、阻燃树脂、浇注树脂、柔性树脂、人造大理石、BMC和DMC树脂，装饰树脂和特种树脂。在的不饱和聚酯市场中，增强（FRP）树脂的比例仅占40%，而非增强树脂的比例高达60%。在非增强树脂中，工艺树脂占34%，纽扣树脂占24%，人造大理石占19%。
It is widely used for its excellent mechanical performance, electrical performance, chemical corrosion resistance and simple processing technology. MALEIC anhydride manufactures more than 400 brands of unsaturated polyester resins, mainly including O, m, P, and BPA. MALEIC anhydride manufacturers include general purpose resins, chemical resistant resins, flame retardant resins, casting resins, flexible resins, artificial marble, BMC and DMC resins, decorative resins and specialty resins, depending on their use and function. In China’s unsaturated polyester market, the proportion of reinforced (FRP) resin accounted for only 40% , and the proportion of non-reinforced resin as high as 60% . Among the non-reinforced resins, process resin accounted for 34% , button resin for 24% and artificial marble for 19% .
顺酐在加氢产品（包括BDO、THF和GBL）中的应用，特别是在新型热塑性工程塑料聚对苯二甲酸丁二醇酯（PBT）和聚四甲基醚乙二醇（PTMEG）中的应用作为氨纶的原料，是过去10年乃未来很长一段时间内能够显著推动全球马来酸酐产品快速增长的主要因素。
The application of maleic anhydride in hydrogenated products (including BDO, THF and Gbl) , especially in the new thermoplastic engineering plastics PBT and PTMEG as raw materials for SPANDEX, mALEIC anhydride has been a major factor in the rapid growth of global consumer products over the past decade and beyond.
到目前为止，除了顺酐生产厂家的10000吨年BDO和2000吨年THF操作装置，没有以顺丁烯二酸酐为原料的新加氢产品装置的建设和运行。此外，金昊化工建设的15000吨年顺丁烯二酸酐生产装置已无法启动，因此需要采购顺丁烯二酸酐产品
So far, no new hydrogenation units have been built or operated in China using maleic anhydride as feedstock, except for the 10,000 ton annual BDO and 2,000 ton annual THF operating units of MALEIC anhydride producers. In addition, the 15,000 ton annual MALEIC anhydride plant built by Jinhao chemical has been unable to start, so it needs to purchase maleic anhydride products
顺丁烯二酸酐主要用于醇酸树脂涂料和氨基树脂涂料。醇酸树脂涂料是18种涂料中消耗量的一种。
顺酐生产厂家产量和消耗量约占涂料总量的三分之一。醇酸树脂具有良好的附着力、光泽和耐腐蚀性。广泛应用于建筑涂料、机械和汽车涂料、家具和防腐涂料；氨基树脂涂料还具有良好的硬度、光泽和保色性能。广泛应用于轻工家电装饰涂料中。
MALEIC anhydride is mainly used in alkyd and Amino Resin coatings. Alkyd resin coating is the largest consumption of 18 kinds of coating. MALEIC anhydride production and consumption of about one-third of the total volume of coatings. Alkyd resin has good adhesion, gloss and corrosion resistance. Widely used in architectural coatings, mechanical and automotive coatings, furniture and anti-corrosion coatings; Amino Resin coatings also have good hardness, gloss and color retention. It is widely used in decorative coatings of light industry household appliances.
