The Stepan Value Proposition

4

STEPANPOL® polyester polyols are designed for use in a wide variety of polyurethane and polyisocyanurate applications. We offer a full range of polyols, including those for C.A.S.E. (Coatings, Adhesives, Sealants, Elastomers), Flexible Foam, and Rigid Foam applications. RUCOTE®

powder resins provide a broad range of high quality properties for powder coatings. Stepan’s technical excellence is key in the development of polyester polyols and our production expertise delivers results: our polyols offer unique performance and are of the highest quality, clarity and consistency. Collaborative screening is the key to performance. Stepan offers complete screening of our polyols in your application, a service that our customers truly value. You provide the formulation, we test it using our raw materials and deliver the performance results to you. It is an efficient way to experience the quality that Stepan materials bring to your end-use product while getting the benefit of knowing your formulation has been tested to the highest standard. Stepan ensures that confidentiality issues are respected throughout all stages of the process.

We excel at innovation: our global Research and Development team —over 150 people strong—is constantly striving to improve existing products and develop new answers to formulation challenges. While our synthesis techniques and testing abilities are always evolving, we remain focused on the needs of our customers. This leads to successful new product development.

RIGID

Typical End Uses Stepan is the global leader in the production and sale of aromatic polyester polyols for use in rigid polyisocyanurate and polyurethane foams. The largest end use for Stepan rigid aromatic polyester polyols is in applications where insulation, flammability, and structural performance are most important. These polyols contain innovative Stepan technology that improves foam processing and insulating performance to create value in end use applications. Stepan’s aromatic polyester polyol business uses a vertical integration model, world-class manufacturing and a global supply chain to deliver quality and reliability.

POLYESTER POLYOLS FOR RIGID POLYISOCYANURATE (PIR) AND POLYURETHANE (PUR) FOAM. Increasing energy efficiency through improved insulation

SPRAY INSULATION

Stepan’s unique chemistry leads to superior insulation and flammability resistance, critical requirements in the construction industry. Spray formulations containing STEPANPOL® polyols are also easier to process due to low polyol viscosity and improved blowing agent solubility.

BOARDSTOCK INSULATION

PIR foams made with STEPANPOL® polyester polyol deliver superior insulating performance, applied economics and reliability. This results from the combination of our proprietary technology, application expertise, and world-class manufacturing practices.

APPLIANCE INSULATION

STEPANPOL® polyols produce PUR foams with finer cell structures and improved flow. This enables manufacturers to increase insulating value while reducing cost.

The largest end use for Stepan rigid aromatic polyester polyols is in applications where insulation, flammability, and structural performance are most important. These polyols contain innovative Stepan technology that improves foam processing and insulating performance to create value in end use applications. Stepan’s aromatic polyester polyol business uses a vertical integration model, world-class manufacturing and a global supply chain to deliver quality and reliability.

POLYESTER POLYOLS FOR RIGID POLYISOCYANURATE (PIR) AND POLYURETHANE (PUR) FOAM. Increasing energy efficiency through improved insulation

SPRAY INSULATION

Stepan’s unique chemistry leads to superior insulation and flammability resistance, critical requirements in the construction industry. Spray formulations containing STEPANPOL® polyols are also easier to process due to low polyol viscosity and improved blowing agent solubility.

BOARDSTOCK INSULATION

PIR foams made with STEPANPOL® polyester polyol deliver superior insulating performance, applied economics and reliability. This results from the combination of our proprietary technology, application expertise, and world-class manufacturing practices.

APPLIANCE INSULATION

STEPANPOL® polyols produce PUR foams with finer cell structures and improved flow. This enables manufacturers to increase insulating value while reducing cost.
