DouwinChemical is a adipic acid factorywhose average employee age is less than 30 years old, and one that has gained a certain reputation in the industry. In 2017, Suzhou Douwin Chemical Co., Ltd. was listed as a key private enterprise in Taicang City. Our company has the advantages of geographical location and the forefront of business philosophy. The most fundamental one is the cohesion of outstanding talents.It provide types of chemical compounds, such as adipic acid, maleic anhydride, phthalic anhydride, acrylic acid and so on.
UPR
Unsaturated polyester resin refers to the polycondensation reaction of diacids and diols to form a polymer containing unsaturated double bonds.And the maleic anhydride usesare very wide.
Specifications of UPR
Unsaturated polyester resin is a kind of thermosetting resin, when it is in the action of heat or initiator, can be cured into a kind of insoluble and insoluble polymer network polymer. However, the polymer has low mechanical strength and cannot meet the requirements of most applications. When reinforced with glass fiber, it can become a composite material, commonly known as "fiberglass". Compared with resin casting, the mechanical strength and other properties of FRP have been greatly improved.
How is maleic anhydride applied to UPR?
UPR is made up of styrene, PA, MA, DEG, propylene glycol, ethylene glycol, and others.
We provide maleic anhydride derivatives, maleic anhydride grafted, pp grafted maleic anhydride, maleic anhydride and water,etc.
