The effect of nanoclay in combination with other inter fillers in ethylene propylene diene monomer (EPDM) rubber vulcanizate were studied. Curing characteristics were carried out using rubber process analyzer (RPA). Mechanical, thermal and morphology characterization of EPDM nanoclay composites were studied.

The aim of this study is to investigate the effect of particles as filler in soft rubber sensors installed in artificial skin. We examine sensors made of natural rubber (NR-latex) that include magnetic particles of Ni and Fe₃O₄ using magnetic compound fluid (MCF). The 1-mm thickness of the electrolytically polymerized MCF rubber makes production of comparatively thin rubber sensors feasible. We...

In this paper the effect of a novel bifunctional additive [cyclic butylene terephthalate (CBT)] was investigated on the rheological, curing and mechanical properties of natural rubber (NR), styrene butadiene rubber (SBR), oil extended styrene butadiene rubber (oSBR), acrylonitrile butadiene rubber (NBR) and ethylene propylene diene rubber (EPDM). Results showed, that CBT acted as an effective l...

afinite element model is developed for simulation of the curing process of a thick axisymmetric rubber article reinforced by metal plates during the molding and cooling stages. the model consists of the heat transfer equation and a newly developed kinetics model for the determination of the state of cure in the rubber. the latter is based on the modification of the well-known kamal-sourour mode...

Introduction Vulcanization refers to a specific curing process of rubber involving high heat and the addition of sulfur or other equivalent curatives. It is a chemical process in which polymer molecules are linked to other polymer molecules by atomic bridges composed of sulfur atoms or carbon-to-carbon bonds. The end result is that the springy rubber molecules become cross-linked to a greater o...

The aim of the present study was to evaluate the performance of dental practitioners incorporating attachments into overdenture prostheses, via the direct method, before and after an instructive course. Forty randomized gypsum models, with implants either angulated or parallel to each other, were given to forty dentists before and after an instructive course. A rubber dam or temporary light-cur...

OBJECTIVES Workers in the rubber industry are exposed to a complex mixture of hazardous substances and have increased risk of developing several diseases. However, there is no up to date survey examining the exposure in the Swedish rubber industry. One of the toxic compounds in the industry is carbon disulfide (CS(2)), which is biotransformed to 2-thiothiazolidine-4-carboxylic acid (TTCA). TTCA...
