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, maleic anhydride, PA, DEG, propylene glycol, ethylene glycol, and others.

Unsaturated polyester resins are widely used in a variety of industries, such as composite materials, wood paint, quartz, marble and artificial cement.
