Germany's Jowat AG Uses Unique CO2-Based Polyols To Improve Performance of Hot Melt Adhesives
WALTHAM, Mass. – Novomer Inc., a sustainable materials company pioneering a family of high-performance polymers and other chemicals from renewable feedstocks such as carbon dioxide (CO2), has announced that Jowat AG, a leading supplier of industrial adhesives headquartered in Germany, is the first to commercially adopt Novomer’s new Converge® polypropylene carbonate (PPC) polyols for use in polyurethane hot melt adhesive applications.
“The commercial adoption by Jowat is a significant milestone in the commercial development of our breakthrough technology and we expect to attract additional customers in CASE (Coatings, Adhesives, Sealants, and Elastomers) applications,” said Peter Shepard, Chief Business Officer for Novomer Inc. “Converge® polyols delivered a sustainability advantage and helped Jowat improve the performance of one of their reactive hot melt products.”
Jowat was able to leverage the technical advantages of Novomer’s Converge® polyols to develop a new formulation, said Klaus Kullmann, Managing Director/Sales and Marketing for Jowat AG. “We were able to help a customer improve the hydrolytic stability of their reactive hot melt without compromising on green strength and productivity,” said Kullmann. “Converge® polyols are unique materials and will help differentiate many more of our products in the future.”
Converge® polyols are designed to replace conventional petroleum-based polyether, polyester, and polycarbonate polyols. They are based on the co-polymerization of carbon dioxide (CO2) and epoxides and the resulting products contain more than 40% by weight CO2. The use of waste CO2 as a significant raw material yields a product with an extremely low carbon footprint. In addition, since waste CO2 is significantly lower in cost than conventional petroleum-based raw materials, Converge® polyol manufacturing costs are favorable compared to conventional polyols when produced at full commercial scale.
In terms of performance, Novomer's Converge® polyols have a unique polycarbonate backbone which increases the strength and durability of polyurethane products. Incorporating these new polyols into existing formulations yields foams with higher tensile and tear strength, and increased load bearing capacity; adhesives and coatings with improved adhesion, cohesive strength, and weatherability; and elastomers with greater tensile and flexural strength.
In addition, the high CO2 content enabled by Novomer's proprietary technology produces polyols with a calorific content (heat of combustion) that is 40% to 50% lower than conventional polyether, polyester, and polycarbonate polyols. This inherent feature is especially important in polyurethane applications that must meet strict flammability requirements.
The new Converge® polyols are available globally. The company’s initial product offerings – 1000 and 2000 molecular weight grades - are manufactured at a multi-thousand-ton commercial-scale toll facility in Houston, Texas. Novomer continues to work closely with several major companies on new applications for various segments of the polyurethanes industry.
