Abstract:

Option for recycling waste cooking oil to produce renewable microporous foam is an alternative plastic product for noise reduction application. The emerging alternative is to use hydroxylated monomer from renewable oils is to generated microporous plastic or polymer foam. Another process is referred with the addition of synthetic epoxy and filler by different ratio of renewable monomer. Fabrication of this plastic foams were divided into synthetic epoxy foam and renewable epoxy foam that was produced from palm oils. A good sound absorption material for noise reduction purposes is to give effects on the absorption rather than to reflect the sound. Other property related to the service life of the plastic foams is from the examples of exposed to ultra-violet (UV) irradiation in UV Weatherometer. The morphological foams structures were also investigating to identify the influences of microporous structure towards noise reduction application. The density of the plastic foams was evidently changed with the increment of pore sizes contributed from the decrement of filler. The highest sound absorption coefficient; α indicating noise reduction on the applied plastic foams referring to different type of epoxy or composition ratio of filler.  This is also indicating that the fabricated polymer foams contributed to the main parameter for noise reduction application in any applied space.
