Abstract
In its application, Ca-stearate served as a processing aid to smooth the flow of rubber in the mold and reduce the viscosity value during the printing process of rubber goods. This study aims to observe the application of ca-stearate synthesis of palm oil derivatives compared to commercial ca-stearate manufacturing rubber goods between rubber processing aid (RPA) formulas. The testing was adjusted to the industry's evaluation parameters for the rubber goods production process. The results of the Spiral Flow Test showed that the length of rubber flow with RPA was 53.14%, and the commercial RPA was 38.16% longer than without RPA. The weight of rubber samples with RPA was 54.86%, while the commercial RPA was 42.58% heavier than without RPA. As for the hardness value, the change in the value of the Compression set was 25%, 100o C, 72hrs, Tensile Strength (tensile strength), and Elongation at Break. The rubber processing aid formulation of Ca-based palm oil derivatives excels in the 3 PHR rubber formula; 68kgf, 2.72kg/ cm2, 966.713kg/cm2, and 145.75%.
