Electrospinning allows producing fine polymer fibers with diameters in the range of several hundred nanometers up to some micrometers. While a large amount of polymers necessitates spinning either from melt or from solutions which are hazardous to he

The industrial production of prototypes made of polyurethane via silicone molds in the vacuum casting process is one of the most widespread applications of rapid tooling. The silicone molds show progressive deterioration, as the isocyanate component

In this study, we investigate the anomalous diffusion of methylene diphenylmethane-4,4'-diisocyanate (MDI) into fumed silica filled poly(dimethylsiloxane) (PDMS) elastomer, which occurs in the industrial application of polyurethane vacuum casting. Th

In this work we present a new method to enhance the durability of silicone molds, which are used in industrial processes for small batch production. The goal is to reduce the aging effects of the molds that occur after a minor number of casting proce
