What are biobased polyols?
Polyols are the primary component utilized in the synthesis of polyurethanes. Biobased polyols are produced from renewable resources.
The market for biobased polyols has grown rapidly in recent years as the world has shifted toward greater sustainability. Products that incorporate sustainably produced and environmentally friendly materials have an inherent advantage in the marketplace. What is an advantage in the marketplace today may very well become a standard requirement in the future.
Consider this excerpt taken from a perspective article, From Lab to Market: Current Strategies for the Production of Biobased Polyols, published by the American Chemical Society:
In the interest of improving the sustainability of the polyurethane industry, for more than a decade the market has undergone a shift toward biobased polyols made from renewable resources. For this reason, the demand of biobased polyols has grown rapidly and offers new opportunities to valorize biomass into technical grade polyols for the polyurethane industry.
Using ChemRes™ 226 Polyol Resin in Coatings, Slurries, and Trowel Mortar Systems
ChemRes™ 226 polyol resin is an aqueous, OH-reactive emulsion produced by Cargill that can be used as a component of a three-part, resin-based, cementitious-polyurethane flooring system. When formulated, ChemRes™ 226 polyol resin produces high performance properties in coatings, slurries, and trowel mortar systems. As a concrete coating, ChemRes™ 226 polyol resin exhibits good durability through high compressive and bond strength.
Adding ChemRes™ 226 Polyol Resin to coatings, slurries, and trowel mortar systems brings several advantages:
- Thermal shock resistant
- Thermal cycling properties
- Impact and abrasion resistance
- Resistant to steel cart traffic
- Similar thermal expansion to concrete
- Resistant to sanitizing chemicals
- Excellent corrosion and chemical resistance
- Suitable for high modulus formulations

Excerpt from the article abstract:
This Perspective aims to summarize current strategies to produce polyols from biomass and the problems associated with their market implementation. Different natural resources, including lignocellulose, lipids, or carbohydrates for the synthesis of biobased polyester- or polyether-based polyols and polyphenols will be reviewed. Subsequently, the gaps that are currently preventing the transition from academic laboratories to industrial plants will be commented upon, highlighting in particular the use of nonscalable chemical transformations and the lack of competitive biobased raw material suppliers. Finally, a case study of the issues associated with the scale-up process of novel biobased polyols will be discussed in detail.
