Rigid PU Foam Applications

Resource efficiency and thermal insulation is one of today‘s most important issues. Growing environmental awareness and constantly rising energy prices have helped to increase the demand for materials with strong insulation properties. Good insulation can help reduce heating costs in new buildings, but also help to improve energy efficiencies in older buildings. Insulation also helps to reduce unnecessary energy losses and save power costs of household and commercial refrigerators and freezers. Insulation materials found in polyurethane foam considerably reduce heat loss through building roofs and walls, and make an essential contribution to the outstanding properties of polyurethane rigid foam used in the insulation of refrigerators.  

The unique cell structure of polyurethane foam is responsible for its superb insulation properties. At Evonik, our polyurethane additives have a big influence on cell structure and enable the optimization of the essential insulation properties demanded in the production of polyurethane foams.

We provide polyurethane additives for insulation panels used in commercial and industrial wall and roof insulation. Used in a range of applications, we offer polyurethane and polyisocyanurate foam additives in flex-faced, metal-faced and continuous panel types. Our additives can provide increased insulation values, better surface quality, improved adhesion, a wider processing latitude, and reduced smoke and flame generation. For the manufacture of the various types of PIR and PUR insulation panels, we offer a full additives package of silicone surfactants, amine & metal catalysts


The discontinuous panel market has become a growth area for polyurethane foam due to the innovative applications that require new solutions to meet the new demands. Our additives can help improve performance features on foams using various blowing agents, alternative equipment requirements and differing geometrical designs. With additives that contribute to insulation value, flow enhancement, or blowing agent retention, we offer an extensive range of silicone surfactants, amine catalysts and release agents.


As the demand for efficiency pushes the need for more advanced appliance foam, our polyurethane additives help to create performance advantages.

To achieve increased insulation properties, our products can improve the flowability of foam through increasingly complex cabinet designs and reduce foam defects to help achieve new standards for energy loss. For improved insulation of refrigeration appliances, such as household and commercial refrigerators and freezers we offer a broad range of silicone surfactants, amine catalysts and special back-end curing catalysts.

Spray Foam

The changing needs of the fast growing spray foam market require diverse chemistries to help take advantage of the unique value that spray foam can bring to the home or building owner.

Additive selection is important when developing open-cell and closed-cell spray systems. Our additives help to create the performance advantages you need to incorporate new raw materials, broaden your portfolio choice for applicators, and continue to adapt to the demands of new regulations for construction.

To meet the changing government regulations and create performance advantages for open-cell and closed-cell spray systems, we offer a broad range silicone surfactants, amine & metal catalysts, cell openers and emulsifiers.


To help meet the many application challenges that construction professionals and to do-it-yourself consumers face in one component foam, we continue to support and develop advanced chemistries. Our polyurethane additives can create performance advantages by helping to achieve better winter performance, increased foam yields, extended shelf life and enhanced fire retardant capabilities.

We offer a strong portfolio of silicone surfactants, amine catalysts and cell openers to help increase product and process efficiency in one component foam.

Pipe Insulation

The growing Oil and Gas Industry is driving the need for more polyurethane foam solutions to improve pipe insulation. Our additives target both the insulation, and compressive strength needed to meet the demands in this challenging field. We offer a variety of polyurethane additives to meet the ambitious performance targets and requirements of the pipe insulation industry; these include silicone surfactants and amine & metal catalysts.
