Expandable Graphite Systems for Phosphorus‐Containing Unsaturated Polyester, 2

Abstract: A series of flame-retardant-containing unsaturated polyesters have been developed. The flame retardants include expandable graphite (EG) and phosphorous-containing materials (ammonium polyphosphate (APP) and triphenyl phosphate (TPP)). The flame-retardant properties of these samples were investigated by thermogravimetric analysis (TGA), limiting oxygen index (LOI), and UL-94 tests. Moreover, the kinetic parameters of these flame-retardant-containing unsaturated polyesters were calculated by the Coats and Redfern method, the Ozawa method, and temperature modulated thermogravimetric analysis (MTGA). The differences and relationship among different analytical methodologies were investigated. Pyrolysis gas chromatography mass spectrometry (Py/GC/MS) was also used to investigate the pyrolysis products of the samples.

Study on the Thermal Decomposition Behavior of[ABS/PC/Triphenyl Phosphate/Transition Metal Chloride] Compounds

Abstract: The thermal degradation of ABS/PC/triphenyl phosphate compounds in the presence of transition metal chloride catalysts has been studied by thermogravimetric analysis (TGA). The reaction of transition metal chloride catalysts (cobalt chloride, ferric chloride, nickel chloride and zinc chloride) and ABS/PC/triphenyl phosphate compounds has been found to occur during the thermal degradation of the compounds. In a nitrogen atmosphere, char formation is observed, and of the reaction product is non-volatile at . The resulting enhancement of char formation in a nitrogen atmosphere has been explained as a catalytic crosslinking effect of transition metal chloride catalysts. On the other hand, transition metal chloride catalyzed char formation of ABS/PC/triphenyl phosphate compounds in air was unsuccessful due to the oxidative degradation of the char at a higher temperature.

Phase change heat-conductive molding

Abstract: PROBLEM TO BE SOLVED: To obtain a phase change heat-conductive molding, which has excellent heat conduction performance and readily increases handleability and transfer properties SOLUTION: The phase change heat-conductive molding is obtained by molding a phase change heat-conductive composition, comprising a styrene-based elastomer, paraffin oil, a heat-conductive filler and a plasticizer having 40-60°C freezing point The plasticizer in an amount of 50-400 parts wt is added to the styrene-based elastomer in an amount of 100 parts wt The plasticizer is preferably triphenyl phosphate The phase change heat-conductive filler has a sheetlike form and is set to 50-300 μm thickness at COPYRIGHT: (C)2006,JPO&NCIPI
