Innovative Technologies

As a leader in polyurethanes manufacturing and with technological leadership as a core competency, Dow is constantly working to improve processing efficiencies and product performance, including developing a generation of more economically viable and environmentally sustainable products. Dow’s polyurethanes product line continues to grow and evolve to meet customers’ changing requirements and address environmental guidelines. Recent technological developments include:


VORANOL™ VORACTIV™ polyols have generated strong interest among flexible and molded foam manufacturers and within the automobile, bedding and furniture industries since their introduction in 2001. These technologically enhanced polyols have the amine catalyst grafted into them, allowing foam manufacturers to eliminate a formulating step. This streamlines the production process, generates significant cost savings and improves foam consistency and performance. The polyols also generate lower VOC emissions than those associated with amine catalysts, thereby reducing odors in the manufacturing environment and in key end-use markets, including furniture, bedding and automotive. In automotive interiors, VORANOL VORACTIV polyols are also known to help reduce windshield fogging, polycarbonate degradation and PVC staining.

Viscoelastic Foam

Dow’s VORANOL VORACTIV polyols were specially designed for application in viscoelastic foams, whose use as the upper layer in high mattresses and luxury couches has grown considerably in recent years. Dow is developing industry-leading solutions for superior performance memory foam. VORANOL VORACTIV polyols reduce the consumption of amines and eliminate production steps and reduce production costs in the manufacture of viscoelastic foam. Viscoelastic foams offer numerous performance benefits, including their ability to conform to body shape, provide customized resilience and demonstrate excellent load bearing properties.

Natural oil-based polyols

Dow continues to make significant progress in the development of natural oil-based polyols that can be used in lieu of a significant percentage of hydrocarbon-based polyols in urethane formulations. This development, being tested mainly for flexible polyol products first, allows natural oils to be selectively modified, impacting final urethane product performance. So far, production success has been achieved at the lab and pilot-plant scale and key product properties have been matched with formulations incorporating at least 35% soy monomer. Trials are underway with select customers as the product advances in its developmental and testing phase. The exploration of natural oil-based polyols is part of Dow’s efforts to offer products with greater economic stability and environmental sustainability.

Mannich Polyols

We have recently introduced our new product, VORANOL WR 2000 Mannich polyols used in spray foam for roofing and construction. This Mannich-based polyether polyol offers the lowest viscosity in the industry, allowing easier processing and faster spray. It also provides good compression strength and dimensional stability, in addition to increased environmental benefits through reduced blowing agent use.


Dow offers a wide range of polyether polyols and pure, modified and polymeric MDI, specialty prepolymers and polyurethane dispersions for use in formulating coatings, adhesives, sealants and elastomers (CASE). As the dynamic CASE market undergoes rapid changes in performance and environmental requirements, Dow’s polyurethanes chemistry and systems formulation expertise brings about technologically innovative changes to meet the evolving performance needs of customers in a range of applications. Dow has developed products and application technologies that address the specific performance requirements of customers, while keeping with the highest quality and EH&S standards.
