Flexible Polyurethane Foams Filled with Coconut Coir Fibres and Recycled Tyre - Part I: Production and Morphology

Abstract:

In this paper, the use of waste and recycled materials that is coconut coir fibres and recycled tyre particles, as fillers filled in flexible polyurethane (PU) foams were studied and analyzed. The composites developed were aimed to use in cushioning applications. There are five different types of free-rise filled-foams were produced by one-shot method. The thermal analysis indicated that it is possible to added coir fibre and recycled tyre to PU formation since they have high thermal stability; 250°C for organic compounds in coir and 350°C for rubber elements in tyre. Through many trials in production, the filled-foams were decided to fabricate with 2.5wt% filler content. The low loading fraction was found causes by effect of fillers to foaming ability as well as foaming rate due to the viscosity created. Besides, the results of morphology studied revealed that filled-foams having cellular structures of possess smaller cell sizes and higher cell densities. The mean cell size of flexible PU filled with 2.5wt% (80P20F) is 23.785% lower than the pure foam
