順丁烯二酸酐在玻璃鋼工業中主要用作不飽和聚酯樹脂（UPR）的原料；1,4-丁二醇（BDO）、四氫呋喃（THF）和γ-丁內酯（GBL）；還用于涂料、潤滑油添加劑、農藥、酒石酸、琥珀酸和酸酐、四氫苯酐、改性松香等不飽和聚酯樹脂（UPR）：是熱固性樹脂的主要品種之一。
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.
它以其優異的機械性能、電氣性能、耐化學腐蝕性和簡單的加工工藝而被廣泛應用。順丁烯二酸酐制造商經營400多個的不飽和聚酯樹脂，主要包括鄰苯型、間苯型、對苯型、雙酚a型等。順酐廠家根據用途和功能，它們包括通用樹脂、耐化學樹脂、阻燃樹脂、澆注樹脂、柔性樹脂、人造大理石、BMC和DMC樹脂，裝飾樹脂和特種樹脂。在的不飽和聚酯市場中，增強（FRP）樹脂的比例僅占40%，而非增強樹脂的比例高達60%。在非增強樹脂中，工藝樹脂占34%，紐扣樹脂占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% .
順酐在加氫產品（包括BDO、THF和GBL）中的應用，特別是在新型熱塑性工程塑料聚對苯二甲酸丁二醇酯（PBT）和聚四甲基醚乙二醇（PTMEG）中的應用作為氨綸的原料，是過去10年乃未來很長一段時間內能夠顯著推動全球馬來酸酐產品快速增長的主要因素。
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.
到目前為止，除了順酐廠家的10000噸年BDO和2000噸年THF操作裝置，沒有以順丁烯二酸酐為原料的新加氫產品裝置的建設和運行。此外，金昊化工建設的15000噸年順丁烯二酸酐裝置已無法啟動，因此需要采購順丁烯二酸酐產品
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
順丁烯二酸酐主要用于醇酸樹脂涂料和氨基樹脂涂料。醇酸樹脂涂料是18種涂料中消耗量的一種。
順酐廠家產量和消耗量約占涂料總量的三分之一。醇酸樹脂具有良好的附著力、光澤和耐腐蝕性。廣泛應用于建筑涂料、機械和汽車涂料、家具和防腐涂料；氨基樹脂涂料還具有良好的硬度、光澤和保色性能。廣泛應用于輕工家電裝飾涂料中。
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.
