During the 1960s styrene block copolymer became available, and in the 1970s a wide range of TPEs came on the scene. The worldwide usage of TPEs (680,000 tons/year in 1990) is growing at about nine percent per year. The styrene-butadiene materials possess a two-phase m…

WebbIt presents PU chemistry, the foaming processes, the physics behind the foam structures, and then typical microstructures. PU foams are treated separately from foamed thermoplastics because the processing differs and the foam geometry is dominated by surface tension effects. Webb10 okt. 2024 · The objective of this work is to study the influence of the ratio between the elastomer (EPDM) phase and the thermoplastic phase (PP) in thermoplastic vulcanizates (TPVs) as well as the associated morphology of the compression set of the material. First, from a study of the literature, it is concluded that the rubber phase must be dispersed … computer screen is white after startup

WebbThe aim of this study is the preparation of star-shaped branched polyamides (sPA6) with low melt viscosity, but also with improved mechanical properties by reactive extrusion. This configuration has been obtained by grafting a tri-functional, three-armed molecule: 5-aminoisophthalic-acid, used as a linking agent (LA).
