Abstract

Natural rubber latex products filled with bleached banana skin powder were identified by burying samples in soil. Soil burial was carried out by adding NPK fertilizer and without fertilizer. One of the tests which was carried out was weight loss calculation. Weight loss calculation showed that natural rubber latex products filled with bleached banana skin powder biodegraded faster than natural rubber latex products without filler. The addition of fertilizer also contributed to biodegradability of samples. The other test was FTIR (Fourier Transform Infrared Spectroscopy) test. The results of FTIR test showed there were structure changes in natural rubber latex which indicated natural rubber latex had been biodegraded.

Abstract

The effect of exposing bleached banana skin powder-filled natural rubber products to sun light and weather with variation of bleached banana skin powder filler loading. Banana skin powder was dried and bleached with hydrogen peroxide and made into disperse system. Natural rubber latex was compounded with bleached banana skin powder with filler loading of 0 to 20 phr (per hundred rubber). Natural rubber latex products, which were produced, were hung in air and exposed to sun light and weather. The degradation of bleached banana skin powder-filled natural rubber products were evaluated by calculating weight loss of samples and performing Fourier transform infrared spectroscopy (FTIR) test. Natural rubber latex lost weight after exposure to sun light and weather from 1 to 16 weeks due to photo-oxidation process.
