POLYESTER RESINS MARKET OVERVIEW

Global Polyester Resins market size is projected to rise from USD 18.8 billion in 2025 to USD 19.646 billion in 2026, reaching around USD 27.938 billion by 2034, progressing at a CAGR of 4.5% between 2025 and 2034.

The COVID-19 pandemic has been unprecedented and staggering, with polyester resin experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

Polyester resins are synthetic thermosetting polymers used in diverse industrial applications. There are two main types: unsaturated polyester resins (UPR) and saturated polyester resins. UPRs are created through the polymerization of unsaturated dibasic acids with diols and can be cured by adding a cross-linking monomer like styrene. They offer excellent mechanical properties, durability, and corrosion resistance, making them widely used in automotive, marine, construction, and composite industries.

On the other hand, saturated polyester resins, formed from saturated dibasic acids and diols, lack unsaturated bonds and do not require a cross-linking monomer. They find application in coatings, adhesives, and powder coatings due to their chemical resistance. Polyester resins' versatility and ease of processing make them popular in various sectors. They offer lightweight yet robust solutions, though their high-temperature performance may be limited. Despite these limitations, the cost-effectiveness and favorable properties of polyester resins make them essential materials for manufacturing composites in construction, transportation, and consumer goods industries.

Key Findings 

COVID-19 IMPACT

Disruptions in Production and Operations Reduced Demand Significantly

COVID-19 had a life changing impact globally. The polyester resin market was significantly affected. The virus had various impacts on different markets. Lockdowns were imposed in several nations. This erratic pandemic caused disruptions on all sorts of businesses. Restrictions tightened during the pandemic due to increasing number of cases. Numerous Industries were affected. However, the market for polyester resin experienced a reduced demand.

The pandemic caused disruptions in global supply chains, affecting the availability of raw materials and components needed for polyester resin production. Restrictions on transportation and trade led to delays and shortages, which, in turn, impacted production schedules and availability of finished products.

The pandemic's economic uncertainty resulted in fluctuating demand for polyester resins. Some industries that heavily rely on polyester resins, such as automotive and construction, experienced reduced demand due to lockdowns, reduced consumer spending, and project postponements. On the other hand, sectors related to personal protective equipment (PPE) and medical supplies witnessed increased demand for certain types of polyester resins used in manufacturing these products. The market is anticipated to boost the polyester resin market share following the pandemic.
