Development of a Plastic Latex Dipping Form

Influence of Surface Roughness on Film Formation and Film Properties of Polypropylene Dipping Former

December 2. 2016 - mahidol-universityThe present research aims to develop a plastic latex dipping former based on talcum-filled polypropylene. The surface roughness on the plastic former is found to play important role on wettability: the greater surface roughness gives the poorer wettability of water but greater wettability of coagulant and pre-vulcanised latex on the former surfaces. In view of film properties, the surface roughness of former does not affect significantly the film thickness prepared using a straight dipping technique, but gives a slightly increase in film thickness if prepared using a coagulant dipping technique. Tensile properties of films prepared are not much different despites the difference in film morphology. Peeling force is increased when the surface roughness of former is increased especially for the thin latex film.
