Waltham, Massachusetts -- Sustainable materials manufacturer Novomer Inc has launched a polypropylene carbonate (PPC) polyol - designated Converge - for use in polyurethane formulations.
Targeted at CASE applications, the products – which have 1000 and 2000 molecular weight grades – are being manufactured at the firm’s 2kT/year facility in Houston, Texas.
Peter Shepard, Novomer Inc’s chief business officer, described the launch as a “significant milestone” adding there had already been “strong interest” from polyurethane producers.
As previously reported at Utech-polyurethane.com, 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.
Novomer will discuss the new materials and present a technical paper on their use in rigid insulating foams at the UTECH North America conference and exhibition (Booth #175) from 4 – 5 June in Charlotte, North Carolina.
