Foam systems optimized with sucrose/glycerin technology

Whether formulating open or closed-cell spray foam systems, our sucrose/glycerin-initiated polyether polyols portfolio is engineered to help you deliver consistency and compatibility. Explore our range to find the polyol for your needs—whether you're fine-tuning mechanical properties, optimizing reactivity, or targeting a specific K factor.

VORANOL™ 280 Polyol

This polyol is useful for partial and all-water-blown, pour-in-place applications. It has a high functionality to support compression resistance and dimensional stability at low OH levels.

VORANOL™ 360 Polyol

A low-viscosity, functional polyether polyol for high and low-density rigid polyurethane foams. It can be used alone or with other polyols and flame retardants. Ideal for use with hydrocarbon or water blowing agents and highly compatible with polymeric isocyanates.

VORANOL™ 370 Polyol

A functional polyether polyol for high and low-density rigid polyurethane foams. It offers excellent crosslinking, dimensional stability under heat and humidity, and is ideal for applications requiring high strength-to-density ratios. Can be used alone or with other polyols and flame retardants.

VORANOL™ 490 Polyol

A functional polyether polyol for high and low-density rigid polyurethane foams. Compatible with various isocyanates, it offers excellent crosslinking and K-factor-to-flowability balance.

More sustainable options to achieve your goals

We’re committed to advancing a circular economy and climate protection supporting your sustainability goals by using alternative feedstocks. We’ve invested in ISCC PLUS certification to trace the flow of bio-based and recycled materials in our value chain and attribute the benefits to final materials using a mass balance approach. Products are available under the Ecolibrium™ portfolio of products with bio-based material and Renuva™ portfolio of products with recycled material. Contact us to learn more.

Built for performance across foam applications

Engineered for consistency and compatibility to help you deliver on desired reactivity and fire performance across open- and closed-cell systems .

VORANOL™ 470X Polyol

A four-functional Mannich polyether polyol which enables a high degree of crosslinking that provides excellent dimensional stability under both humid aging and dry heat aging conditions.

VORANOL™ 425XL Polyol

A low viscosity Mannich polyol that offers exceptional formulating flexibility, enabling production of a wide range of low- to high-density foams. It is autocatalytic, providing superior dimensional stability and strength, and promotes cold surface adhesion.

High molecular weight, high performance

Engineered to consistently deliver on requirements of open-cell systems.

VORANOL™ 4701 Polyol

A high reactivity capped polyether triol with high molecular weight and high primary hydroxyl content. Typical uses include high resiliency, flexible molded and semi-flexible molded foams.

VORANOL™ 2000 LM Polyol

A homopolymer diol with a molecular weight of 2000 mainly used for the manufacture of prepolymers for elastomer, coating, adhesive and sealant.

VORANOL™ CP 6001 Polyol

A triol polyether polyol, capped, 6000 MW, specially developed for the production of flexible HR molded polyurethane foam with TDI, TDI/ PMDI or MDI. It can be used in the production of semi-rigid integral skin foams as well as in the production of cold cure molded foams and high resilience molded.

Where innovation meets polyurethane performance

Standard and high-purity isocyanates designed for optimal reactivity and foam structure.

PAPI™ 27 Polymeric MDI

This product has a narrow molecular weight distribution and high reactivity. It works with rigid polyether and polyester polyols, making it ideal for low- to high-density semi-rigid foams, rigid foams, and structural RIM processes.

PAPI™ 17 Polymeric MDI

Low-viscosity liquid MDI designed for faster reactivity and improved aesthetics, enabling whiter foams. With avg. functionality of 2.7 and max acid spec of 150 ppm, it's ideal for spray foam and other applications needing enhanced reaction speed.
