Growth Trends and Development Insights into Global Unsaturated Polyester Resin Market

Use of Unsaturated Polyester Resins as Composite Materials Helps Meet Infrastructure Requirements at Construction Sites
Published 14 September 2015

Unsaturated polyesters (UP) are macromolecules that belong to the category of thermo-set resins. These resins are advanced products of saturated acids (such as isophthalic acid and phthalic acid) and unsaturated acids (such as maleic or fumaric acid), condensed with dihydric alcohols. They are formed from the condensation reaction between polyols and dibasic organic acids. Asia pacific unsaturated polyester resin market are used in a number of applications such as fiber reinforced plastics (FRP) products, insulation coatings, bulk molding compounds (BMC), sandwich panels, sheet molding compounds (SMC), and pultrusion components. Due to their good mechanical properties, they deliver excellent thermal stability and weather resistance in various applications. 

Growth Trends and Development Insights into Global Unsaturated Polyester Resin Market

The first UP resins synthesized during the thirties were pre-polymers mixed with phenylethylene|vinyl resin|polyvinyl resin} and copolymerized to form a rigid polymer. They were unlike the unsaturated polyester resins available nowadays. These days, the unsaturated polyesters are obtained as matrix resins mainly used for composite materials. They are strengthened with glass fibers and possess high mechanical strength as well as low density.  

Currently, most polyester resin manufacturers across the globe use glycols and acids as a raw material. Various industries such as transport, construction, electrical, marine, and many more are increasingly using unsaturated polyester resins in their daily applications due to the beneficial mechanical properties that unsaturated polyester resins possess. 

Use of UPR across Various End-Use Industries 

Application of unsaturated polyester resins in fiberglass manufacturing is creating abundant opportunities for the market in various industries. According to a leading report by Transparency Market Research, the global unsaturated polyester resins market is expected to witness rapid growth in the near future due to the high use of UP resins in fiberglass reinforced plastics (FRP), which have extensive applications in the construction industry.

Increasing construction activities as a result of infrastructure development in developed as well as in many emerging regions in Asia Pacific and Latin America is expected to significantly influence demand for unsaturated polyester resins in the near future. High demand for composite materials to meet various requirements in building and construction activities is projected to chiefly boost the UPR market’s growth by 2023. 

Moreover, UP resins are broadly classified as DCPD, orthopthalic, isopthalic, and others (consisting of vinyl ester resins and other specialty resins). Vinyl ester resins are considered premium products due to their high cost and performance. In addition, orthopthalic polyester resins are based on orthopthalic acid, while isopthalic polyester resins are based on isopthalic acid. The use of all these chemicals is likely to grow across various chemical and maritime industries, especially in Southeast Asia.

UPR also finds its use in the manufacturing of tanks and pipes in the chemical industries. Due to its superior heat resistance and hydrolytic stability, demand for UP resins is always high across various chemical processing activities. Some of the other end-use industries where unsaturated polyester resins are widely used include artificial stones, electrical, aerospace, wind energy, and automotive.
