DPM Biopolyester polyol
Overview
- Biopolyester polyol is a high-performance, bio-based polymeric polyol derived from renewable feedstocks such as vegetable oils and bio-derived diacids. It is specifically designed for the production of sustainable polyurethane (PU) systems, including coatings, adhesives, sealants, elastomers, and rigid or flexible foams.
- By incorporating biopolyester polyol into polyurethane formulations, manufacturers can significantly reduce their reliance on petroleum-based raw materials while maintaining or even enhancing mechanical performance and hydrolytic stability. This product offers an excellent balance of sustainability, processability, and final-use properties, making it an ideal choice for industries seeking to meet growing environmental regulations and green building standards.
- With its well-defined molecular structure and controlled functionality, biopolyester polyol enables consistent reactivity with isocyanates, ensuring reliable and reproducible polyurethane synthesis across various application platforms.
Product Features
- High bio-based content – Derived from renewable plant-based sources, supporting carbon footprint reduction and sustainable manufacturing initiatives.
- Excellent hydrolytic stability – Engineered ester linkages provide enhanced resistance to moisture attack, ensuring long-term durability in humid or outdoor environments.
- Good mechanical properties – Imparts outstanding tensile strength, tear strength, and elongation at break to finished polyurethane products, suitable for demanding structural and protective applications.
- Broad compatibility – Exhibits excellent miscibility with other polyols (polyether, polyester), isocyanates, solvents, and common additives, facilitating flexible formulation design.
- Controlled reactivity – Features optimized hydroxyl number (OH value) and acid number, ensuring predictable and consistent curing behavior with aromatic and aliphatic isocyanates.
- Low VOC and eco-friendly – Formulated with minimal volatile organic compound content, contributing to safer workplace environments and compliance with strict air quality regulations.
- Versatile application range – Suitable for high-performance coatings, industrial adhesives, elastomeric sealants, and rigid/ flexible foams used in automotive, construction, furniture, and packaging industries.
- Good thermal stability – Maintains structural integrity and performance over a wide temperature range, enabling use in both ambient and elevated-temperature curing systems.
