Effects 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 کاملApplications of Cellulose Nanowhiskers and Lignin In Preparation Of Rigid Polyurethane Nanocomposite Foams
Lignin is the second most abundant biopolymer on Earth, right after cellulose, with a highly complex chemical structure that hinders its possible utilizations. As a consequence, it is mostly burned as an inexpensive resource, generating green electricity or heat that in turn can be used for the deconstruction of biomass itself. Applications that utilize lignin in different manners are of great ...
متن کاملFabrication of novel thermal-expandable microcapsules and their applications in intumescent flame-retardant water-based coatings
Thermal-expandable microcapsules (TEMs) for water-based coatings were synthesized with co-polymer of Acrylonitrile (AN) Methyl methacrylate (MMA) Ethylhexyl acrylate (EHA) Divinylbenzene (DVB) as shell and toluene-p-sulfonyl hydrazide as core by suspension polymerization method. It was found that the microcapsules with desirable thermal expansion property and good heat stability could be obtain...
متن کاملFlame Retardant Applications in Camping Tents and Potential Exposure
Concern has mounted over health effects caused by exposure to flame retardant additives used in consumer products. Significant research efforts have focused particularly on exposure to polybrominated diphenyl ethers (PBDEs) used in furniture and electronic applications. However, little attention has focused on applications in textiles, particularly textiles meeting a flammability standard known...
متن کاملeffect of fire retardants in improvement of combustion restriction and thermal decomposition of polyurethane foams: a review
polyurethane foams are extensively used in different applications such as furnitures and sandwich structures due to better mechanical properties, higher acoustic and damping behavior, higher resistance to hydrocarbon, and aging.with respect to flammability of polyurethane materials and safety precaution in living and working environments there is a vital need to study and investigate published ...
