Preparation and Application of Mold in Polymer Experiments
In polymer experiments,different shapes teflon molds were prepared to test polymer films properties.Different applications need different shapes teflon molds,for example,film drawing test needs rectangle molds,film water pressure resistance test needs circular molds,and film water absorption rate test needs square molds.The depth of the molds decides the thickness of the films,and further decides the different properties of the films.The paper shows the application of the molds.That is though preparing different shapes and thickness poly(vinyl alcohol)(PVA)films in order to research the influence of the thickness to the properties of the films.
