Rigid cross-linked interpenetrated network polyvinyl chloride (PVC) foams are widely used as core materials in the composite industry. Nevertheless, no recycling methods exist today for these that currently landfilled at end of life (EoL). In this work, various amounts EoL PVC form chips were mixed with ethylene–propylene diene monomer (EPDM) rubber and carbon black (CB) 60°C 15 min. The obtain...

This paper studies the collapse of a void in an elastomer caused by osmosis. The void is filled with liquid water, while the elastomer is surrounded by unsaturated air. The difference in humidity motivates water molecules to permeate through the elastomer, from inside the void to outside the elastomer, leaving the liquid water inside the void in tension. When the tension is low, the void reduce...

Dielectric elastomer is one of the new types electronic materials that have both drive ability and electric generating capacity. In this research, fundamental tests were performed to evaluate abilities of dielectric elastomer. As the result, it was found that dielectric elastomer had very efficient drive ability and electric generating capacity, and that it was applicable to both slow and high ...

Inspired by mammalian skins, soft hybrids integrating the merits of elastomers and hydrogels have potential applications in diverse areas including stretchable and bio-integrated electronics, microfluidics, tissue engineering, soft robotics and biomedical devices. However, existing hydrogel-elastomer hybrids have limitations such as weak interfacial bonding, low robustness and difficulties in p...

Porous asphalt pavements are environmentally friendly permeable road pavements. There is a need to improve the strength performance of porous mixtures. Waste Ethylene Propylene Diene Monomer (EPDM) rubber modification mixtures investigated in this study. The mixture was initially designed for selected mix aggregate gradation. EPDM scraps were replaced with filler materials at rate 2 % and 4 tot...

A method of measuring the volume of the human dental pulp cavity is described. The crown of an extracted tooth is divided from its root. .After cleaning the pulp cavity, it is filled with an elastomer, and the fractured tooth surfaces repositioned before the elastomer sets. The tooth is corroded in acid to release the elastomer which is then weighed, and its volume calculated. The method has be...
