<b>The global polyester polyol market will reach US$11.9 billion in 2025</b>

The global bio-based polyester polyol market is gaining momentum

A few days ago, Persistence Market Research released the latest market research report entitled "Polyester Polyol Market: 2012-2016 Global Industry Analysis and 2017-2025 Forecast". Polyol is a liquid, mainly composed of a large number of hydroxyl compounds, which can be divided into polyether and polyester polyols.

Earlier, polyester polyols were used to produce soft and hard foams. In 1957, multifunctional polyester polyols began to be used in the production of polyurethane foam system materials. Although the improvement speed of polyether rigid foam is slower than that of polyether flexible foam, a series of important progress has been made in this field, and polyether rigid foam currently occupies a dominant position in the polyurethane rigid foam market.

To meet the growing demands of consumers and vertical industries, polyester polyol manufacturers are working on expanding their production and their product portfolio. This helps to expand the customer base of each manufacturer and strengthen its market position. For example, in July 2016, Stepan Company expanded its polyester polyols division in Brzeg Dolny, Poland, by adding new reactors.

The expansion supports further growth in the company's Coatings, Adhesives, Sealants and Elastomers business. Other companies in this market include Purinova LLC, Saudi Aramco, Emery Oleochemicals, Huntsman Corporation, Myriant Corporation, and Helios Group, among others.

According to the report, the global polyester polyol market is expected to grow at a compound annual growth rate of 5.3% between 2017 and 2027. In 2017, the size of the market was USD 7.789 billion and is expected to increase to USD 11.964 billion by 2025.

Increased applications in the leather and footwear markets bode well for development

Polyurethane elastomers derived from polyester polyols are the best material for the manufacture of shoe soles and various other footwear products. This is because polyurethane elastomers are strong and durable and meet the core requirements of footwear products.

At the same time, polyester polyol is cheap and its professional application ability makes it an ideal material for footwear soft materials.

In addition, polyester polyols are also suitable for the production of translucent thermoplastic elastomers. In addition, polyester polyols are more thermally stable than polyether polyols, making them suitable for several industrial applications.

In addition, producers of polyester polyols have been working hard to use environmentally friendly raw materials. For example, biosuccinic acid is used to produce polyester polyols in order to significantly reduce the impact on the environment.

This further reduces punitive discounts at lower costs, pushing polyester polyol producers to expand production capacity to meet growing consumer demand.

In addition, this also helps to reduce dependence on petroleum raw materials, which are highly vulnerable to fluctuations in crude oil prices.

Unfavorable chemical and physical properties affecting popularization and application

Polyester polyols will reduce molecular weight and react with acids and alcohols in high temperature and humid environments. Acid end groups are inevitable products of the polyester polymerization process and are able to catalyze this destruction process. These acid end groups can also act as efficient chain scission agents to degrade the linkages of the polyurethane network.

In addition, polyester polyurethane has weak hydrolysis resistance. Polyester polyols are also hygroscopic and to some extent toxic. These unfavorable characteristics hinder the application of polyester polyol in various industries to a certain extent, thereby reducing its market growth rate.
