Oligobutadienes are viscous liquid polymers of butadiene with low relative molecular mass representing the raw material for polyurethanes production, which are widely used not only in the electrical engineering. The article describes the properties and accelerated degradation processes of variously modified oligobutadienes (LB 3000, LB 5000, LBH 3000 and LBM 32) due to effects of UV radiation. The...
This paper deals with the analysis of promising environmentally compatible electrical insulating fluids for electrical engineering. It starts with the overview of the current state of the art and of the latest trends in the use of biodegradable natural oils. In the experimental part, castor oil, linseed oil, sunflower oil and rapeseed oil as well as their components, fatty acid esters, were studied...
