Effect of Different Thickness of Core Layer on Tensile Properties of Laminated Natural Rubber Latex Film

Abstract:

Laminated natural rubber latex with cleaning agent and waste latex compound was prepared by arranging half-cured latex sheets with various thicknesses of core layer then moulding using hot press according to the Rheometer graph. Laminated layers consist of outer layer (natural rubber latex films with cleaning agent) and core layer (waste natural rubber latex film). The core layer and outer layer are prepared through casting method with different thickness. For core layer, three different thickness of film is cast and for outer layer the thickness is control. The aim of this paper is to study the effect of different thickness of core layer and the different molding temperature on tensile and swelling properties of laminated films. The tensile test was carried out to acquire good interfacial adhesion between the laminates films. The fractured surface morphologies were carried out using digital microscope (Dino-Lite) to understand the interfacial interaction between core and outer layer of the films. The use of NRL lamination films with NRL waste will contribute to novel materials for as mould cleaning product with green and easier cleaning compare to conventional cleaning process.
