The Modification of Polyurethane Foams Using New Boroorganic Polyols (II) Polyurethane Foams from Boron-Modified Hydroxypropyl Urea Derivatives
The work focuses on research related to determination of application possibility of new, ecofriendly boroorganic polyols in rigid polyurethane foams production. Polyols were obtained from hydroxypropyl urea derivatives esterified with boric acid and propylene carbonate. The influence of esterification type on properties of polyols and next on polyurethane foams properties was determined. Nitrog...
متن کاملElimination of Amine Emissions from Polyurethane Foams: Challenges and Opportunities
Polyurethanes are a unique class of plastic in the sense that independent manufacturers buy liquid polyols and isocyanates and then react them in the presence of catalysts, surfactants and other additives in widely varying processing schemes to make the final commercial product. In some manufacturing scenarios, there is a growing concern about worker exposure to volatile organic chemicals (VOC)...
متن کاملEffects of silicon surfactant in rigid polyurethane foams
The rigid polyurethane foams (RPUFs) have been fabricated from high functional crude 4,4’-di-phenylmethane diisocyanate (CMDI) and polypropylene glycols (PPGs) for a wide range of surfactant concentration with an environmently friendly blowing agent (HFC 365mfc). Cream time, gel time, and tack-free time increased with the addition of surfactant. Foam density decreased rapidly to a minimum at 0....
متن کاملInvestigation of Industrial Polyurethane Foams Modified with Antimicrobial Copper Nanoparticles
Antimicrobial copper nanoparticles (CuNPs) were electrosynthetized and applied to the controlled impregnation of industrial polyurethane foams used as padding in the textile production or as filters for air conditioning systems. CuNP-modified materials were investigated and characterized morphologically and spectroscopically, by means of Transmission Electron Microscopy (TEM), and X-ray Photoel...
متن کاملNonlinear mechanics of hyper elastic polyurethane furniture foams*
Upholstered furniture intended to provide better sleep and rest, especially furniture for disabled persons, require careful design of elastic spring systems. In the majority of cases, when designing new articles, both furniture designers and manufacturers rely on long-term experience and craftsman’s intuition. On the other hand, the accumulated interdisciplinary knowledge of modern medical labo...
