The Cyclization of Natural Rubber
The effects of solvent, temperature, time, weight percent of catalyst on the rate and mechanism of cyclization of natural rubber (NR) was studied in toluene and xylene solutions having tin tetra chloride catalyst (SnCl4). Iodometric titration show, with 8% SnCl4 (based on polymer weight) cyclization occurs, leaving 27.4% of the total unsaturation. Infrared spectra of c...
متن کاملSurvey of Micro/nano Filler Use to Improve Silicone Rubber for Outdoor Insulators
Among the new insulating materials widely used in high-voltage outdoor insulation, silicone rubber has received the most attention. Indeed, silicone rubbers are gaining in popularity as an effective counter-measure to insulator contamination problems. However, pure silicone rubber shows little tracking and erosion resistance. So, some properties of silicone rubber need to be improved to extend ...
متن کاملTensile and Physical Properties of Linear Low Density Polyethylene-natural Rubber Composite: Comparison between Size and Filler Types
Linear Low Density Polyethylene-Natural Rubber (LLDPE-NR) composites in the ratio of 70:20 were made with different loadings of nanosilica and micro-scale Palm Oil Fuel Ash (POFA). Linear Low Density Polyethylene grafted with maleic anhydride (LLDPE-g-MAH) of 10 wt% was added as a compatibiliser. The composites were produced by using two-roll mill machine. The tensile properties of the composit...

15 صفحه اولZinc Oxide Nanoparticles as an Activator for Natural Rubber Latex
This work focuses on the study the effect of ZnO nanoparticles on the vulcanizate properties of natural rubber (NR) latex films. Zinc oxide nanoparticles were synthesized by a simple and an efficient wet chemical method. The Powder X-ray Diffraction (PXRD) characterization confirmed the successful synthesis of pure ZnO and the average particle size was found to be 50 – 100 nm as indicated by pa...
