Penelitian pengaruh naphthenic oil dan HAF black terhadap sifat pampat tetap pada kompon lis kaca mobil

The objective of the research is to know the influence of naphthenic oil and HAF black properties of the compression set by constant load and constant deflection rubber strip compound. Rubber strip compound is made from natural rubber (RSS) and synthetic rubber (SBR 1502) with the addition of ingredient such as softener, activator, filler, anti oxidant, accelerator and vulcanizing agent. It should be carried out using base formula by varrying naphtenic oil 3; 5 and 7 parts and carbon black 45; 50 and 55 parts for 9 compounds, then it should be tested their physical properties, compression set by constant load and constant deflection. The test is actually able to fullfill the specification of SII 1999-86 “Lis karet kaca kendaraan bermotor”. The result of the test statistically prove that naphthenicc oil and HAF black influence the physical properties.
