Market Segmentation

By Application

1. Solvent
   The solvent segment accounts for a substantial share of the bio-based propylene glycol market. Bio-PG is widely used as a green solvent in paints, coatings, and cleaning agents due to its low toxicity, high solvency power, and biodegradability.

With industries seeking eco-friendly substitutes for volatile organic compounds (VOCs), demand for bio-based PG solvents is growing across industrial coatings, adhesives, and detergent formulations. The trend toward water-based and low-VOC products in manufacturing and household cleaning further supports the expansion of this segment.

2. Chemical Intermediates
   Bio-based PG serves as a vital chemical intermediate in the production of resins, plastics, and unsaturated polyester formulations. It acts as a precursor in various chemical synthesis processes, replacing petroleum-derived glycols in pharmaceutical, cosmetic, and industrial applications.

As the chemical industry transitions toward renewable feedstocks, the use of bio-based intermediates has become increasingly common, driven by both environmental regulations and corporate sustainability goals.

3. Unsaturated Polyester Adhesives
   The unsaturated polyester adhesives segment is experiencing strong growth, propelled by rising construction and infrastructure development. Bio-based propylene glycol enhances the mechanical strength, flexibility, and adhesion of polyester resins used in composites, coatings, and reinforced plastics.

The demand for lightweight, corrosion-resistant materials in automotive and marine industries further contributes to the adoption of bio-based polyester adhesives. Manufacturers are focusing on expanding product lines that balance high performance with environmental responsibility.

4. Antifreeze & Coolant
   One of the largest and fastest-growing applications of bio-based PG is in antifreeze and coolant formulations for automotive, marine, and industrial equipment. Bio-based glycol provides excellent thermal conductivity, corrosion resistance, and biodegradability, making it a safer and more sustainable option compared to traditional ethylene glycol.
