Abstract
The purpose of this research was to study the effect of drying time on the mechanical properties of natural rubber latex filled with cassava peel waste modified alkanolamide. Cassava peel is a waste, containing cellulose which is potential as fillers in natural rubber latex products. Cassava peel waste was dried and milled until the size of 100 mesh. Alkanolamide is one type of non-ionic surfactant which is synthesized from RBDPS (Refined Bleached Deodorized Palm Stearin) and diethanolamine. Alkanolamide has polar group which can modified cassava peel waste and make strong chemical bonding with natural rubber latex. The production of natural rubber latex products was started from pre-vulcanization at 70°C until the system was cured and the chloroform number has reached number 3. Natural rubber latex was formed into films by coagulant dipping and drying method at 120°C for 10 minutes and 20 minutes. Results show that longer drying time will improve the crosslink density and tensile strength of natural rubber latex products until the addition of 15 phr cassava peel waste powder.
