effect of partial natural rubber replaced with synthetic rubbers, styrene butadiene and cis butadiene, on failure and strength properties of bias tread nr/br based compound was studied by efficient and conventional sulfur curing systems and mixtures of different carbon black grades. it was observed that failure behavior comprising tear resistance and crack growth in substituted compounds droppe...

Thermosetting polyurethanes were obtained using an aromatic isocyanate and a hydrophobic polyol formulation from epoxidized soybean oil (ESO) crosslinked with glycerin. A systematic DSC analysis of the effect catalyst type, crosslinker concentration, index ESO crystallization on cure kinetics was conducted. The combination stannic at 0.2 wt% glycerin 20 produced governed by autocatalytic heat f...

Kinetic parameters of the cross-linking reaction porous cellulose membranes with aqueous solutions two different diglycidyl ethers were determined by dynamic DSC experiments. The autocatalytic behavior was described an extended Prout-Tompkins equation. analysis revealed a similar kinetic for both ethers, apparent activation energy 45–65 kJ mol−1 and order between 0.9 1.5, suggesting transition ...

The present framework reports the structural, fundamental parameters, and crystallization kinetics of melt-quenched As30Te64Ga6 chalcogenide glass. energy dispersive X-ray analysis glassy system reveals that constituent element ratio investigated bulk sample agrees with nominal composition. Also, diffraction (XRD) Differential Scanning Calorimetry (DSC) were used to characterize structural prop...

Non-isothermal crystallization and subsequent melting of three grades of ethylene-vinyl acetate copolymer were investigated by differential scanning calorimetry (DSC) technique. The DSC crystallization curves show that vinyl acetate (VAc) content has the same effect on the onset, peak and final crystallization temperatures, and these copolymers have almost the same spacing of thermal windows un...
