  • Novel sulfonate-containing halogen-free flame-retardants ...

    In order to find a more environmentally friendly flame retardant, we have designed a novel halogen-free flame-retardant (FR) system consisting of ternary and quaternary sulfonates centered on adamantane. They are named 1,3,5-tri(phenyl-4-sodium sulfonate)adamantane (AS3) and 1,3,5,7-tetrakis(phenyl-4-sodium sulfona

  • Effect of crosslink structure on mechanical properties ...

    Overall, the flame retardancy of bio-based epoxy resin is not significantly better than DGEBA. This shows that when the cured product does not contain any flame-retardant fillers or elements, the crosslink density has no significant effect on the flame retardancy of the cured product.

    2012-6-5u2002·u2002Flame retardancy. A series of flame retardants differing in PSiN to KSS ratio were manufactured and they were compounded with PC. Table 1 shows the LOI values and UL-94 test for PC compositions. From Table 1, LOI values of the PC/KSS system without PSiN and the PC/PSiN system without KSS are 33 and 31, respectively; both of them just get V-1 class in UL …

  • Effect of cellulose whisker and ammonium polyphosphate

    2015-6-2u2002·u2002Flame-retardant property of PU/APP is decreased remarkably after soaked in hot water. By comparison, that of PU/CWAPP is rarely changed after the same treatment. CWAPP also shows a positive effect on the mechanical property in PU, and compression strength of PU/CWAPP is higher than that of PU/APP with the same content of flame retardant.

    2021-4-1u2002·u2002A bi-functional flame retardant for rigid polyurethane foam (RPUF), denoted as PDEP, was designed and synthesized. PDEP contained two phosphorus-based moieties: phosphophenanthrene (DOPO) and a phosphate (DEP), which may exert different functions at different temperatures. DEP and DOPO moieties in sequence decomposed with increasing …
