The study involved four major activities in estimating the market size of the antimony-free polyesters market. Exhaustive secondary research was done to collect information on the market, the peer market, and the parent market. The next step was to validate these findings, assumptions, and sizing with industry experts across the value chain through primary research. Both top-down and bottom-up approaches were employed to estimate the complete market size. Thereafter, the market breakdown and data triangulation procedures were used to estimate the market size of the segments and subsegments.
Secondary Research
In the secondary research process, various secondary sources have been referred to for identifying and collecting information for this study. These secondary sources include annual reports, press releases, investor presentations of companies, white papers, certified publications, trade directories, certified publications, articles from recognized authors, gold standard and silver standard websites, and databases.
Secondary research has been used to obtain key information about the value chain of the industry, monetary chain of the market, the total pool of key players, market classification and segmentation according to industry trends to the bottom-most level, and regional markets. It was also used to obtain information about key developments from a market-oriented perspective.
Primary Research
The antimony-free polyesters market comprises several stakeholders in the value chain, which include raw material suppliers, manufacturers, and end users. Various primary sources from the supply and demand sides of the antimony-free polyesters market have been interviewed to obtain qualitative and quantitative information. The primary interviewees from the demand side include key opinion leaders in end-use sectors. The primary sources from the supply side include manufacturers, associations, and institutions involved in the antimony-free polyesters market industry.
Primary interviews were conducted to gather insights such as market statistics, data of revenue collected from the products and services, market breakdowns, market size estimations, market forecasting, and data triangulation. Primary research also helped in understanding the various trends related to product type, catalyst, end-use industry, and region. Stakeholders from the demand side, such as CIOs, CTOs, and CSOs, were interviewed to understand the buyers’ perspective on the suppliers, products, component providers, and their current usage of antimony-free polyesters in the market and future outlook of their business, which will affect the overall market.
The breakdown of profiles of the primary interviewees is illustrated in the figure below:
Note: Tier 1, Tier 2, and Tier 3 companies are classified based on their market revenue in 2024 available in the public domain, product portfolios, and geographical presence.
Other designations include sales representatives, production heads, and technicians.

Market Size Estimation
The top-down approach was used to estimate and validate the size of various submarkets for the antimony-free polyesters market for the region. The research methodology used to estimate the market size included the following steps:
-
The key players in the industry have been identified through extensive secondary research.
-
The supply chain of the industry has been determined through primary and secondary research.
-
All percentage shares, splits, and breakdowns based on product type, catalyst, end-use industry, and region were determined using secondary sources and verified through primary sources.
-
All possible parameters that affect the markets covered in this research study were accounted for, viewed in extensive detail, verified through primary research, and analyzed to get the final quantitative and qualitative data. This data was consolidated and added with detailed inputs and analysis, and presented in this report.

Data Triangulation
After arriving at the total market size from the estimation process above, the overall market has been split into several segments and subsegments. To complete the overall market engineering process and arrive at the exact statistics for all the segments and subsegments, the data triangulation and market breakdown procedures have been employed, wherever applicable. The data has been triangulated by studying various factors and trends from both the demand and supply sides. Along with this, the market size has been validated by using both the top-down and bottom-up approaches and primary interviews. Hence, for every data segment, there have been three sources: the top-down approach, the bottom-up approach, and expert interviews. The data was assumed correct when the values arrived from the three sources matched.
Market Definition
Antimony-free polyester identifies a class of polyester products that are manufactured without antimony-based catalysts. Antimony-based catalysts were commonly used as catalysts in the polymerization of polyesters such as polyethylene terephthalate (PET), polybutylene terephthalate (PBT), and polytrimethylene terephthalate (PTT). While antimony trioxide is synthesized from the ore antimony, polyesters can be produced using titanium, aluminum, or tin-based catalysts to manufacture comparable polymer material with less residual toxic material and with less environmental impact. The move away from antimony-based polyesters is being fueled by health and environmental concerns, specifically in food packaging and textiles, as well as medical and consumer applications. Antimony-free polyester offers recyclability, and meets global safety standards and the demands of responsible consumers for safer and more sustainable products, making an antimony-free polyester important across the many sectors by offering products and performance that can compete in green and regulated markets without compromising product performance or quality.
