Rubber materials encounter significant challenges in acidic conditions, resulting in degradation and reduced functionality. This study conducted a thorough comparative analysis of the acid resistance of various rubber compounds formulated from a variety of natural rubber (Ribbed Smoked Sheet and Standard Indonesian Rubber) and synthetic rubber (styrene butadiene rubber, ethylene propylene diene monomer, and isobutene isoprene rubber). The compounds were prepared under identical compounding and vulcanization conditions, and their mechanical properties were assessed before and after immersion in 5
m
hydrochloric acid for up to 21 days. Property changes were analyzed through tensile strength, elongation at break, hardness, abrasion resistance, and swelling behavior to evaluate the extent of degradation due to acid exposure. The results indicate that natural rubber compounds (RSS1 and SIR20) demonstrated relatively better retention of mechanical properties compared to synthetic rubber.
