Flame retardancy of polybutylene terephthalate blended with various oxides

Abstract

ABSTRACT:The flame retardancy of polybutylene terephthalate (PBT) was studied focusing on the effect of various oxides. Thermo-gravimetric analysis, pyrolysis/ gas chromatography/mass spectrometry, and elemental analysis (EA) were used to analyze the flame retardancy, which were observed through the UL-test and a cone calorimeter. Many oxides influenced the flame retardancy and some of them could suppress the flammability of PBT. In particular, the blended-PBTs with ZnO and V 2 O 5 accelerated the degradation and the edges of oxygen consumption were shorter than neat-PBT although the flammability became poorer. The quantitative analysis of the scission products and the results of EA showed that hydrolysis, successive dehydration, and other various reactions changed the scission route to generate less flammable products.

Mass Spectrometry of Synthetic Polymers

“…Flame protection of polymers represents a major issue and can be achieved using a number of different strategies. Ishikawa et al investigated the influence of oxides in polymer blends of PET on its flame retardancy and flammability by means of Py-GC/MS and TGA . Price et al used covalently bonded phosphonate to introduce flame retardancy in PMMA polymers.…”

Evaluate of the Effects of Drilling with Varying Spindle Speed Using Different Thickness of GFRP on the Damage Factor

“…With its high stiffness and strength to weight ratio, makes them a popular option especially as the reinforcing elements in the composite materials [10]. It is important to control the ration between the matrix and fiber in order to archive the desire properties [11]. The mechanical properties of fiber reinforced composites were very dependent on content of the reinforcing fiber, thus high fiber volume fraction is preferred [12].…”

Thermal degradation of polyester–metal oxide mixtures: Fibrous morphology of carbonaceous compounds and pyrolysis products distribution

“…In the view of the increasing production, studies on thermal degradation behaviour of other commercial polyesters, such as poly(butylene terephthalate), PBT, poly(trimethylene terephthalate), PTT, and poly(ethylene naphthalene-2,6-dicarboxylate), PEN are also reported in literature [1][2][3][4][5][6]. Moreover, the influence of the addition of metal oxide and hydroxide has been studied with respect to the selective recovery of benzene from PBT and PEN [1], and flame retardancy of the polyester resins [7].…”
