Sound and vibration damping in automobile industry cause manufacturers to use insulators in automobile parts. High performance polymers are the best choice for noise reduction application. The addition of commercial polymers to bitumen base insulators of Ayegh Khodro Toos (AKT) Co. improved their performance. Effect of polymers such as styrene-butadiene-styrene (SBS), styrene butadiene rubber (SBR) and butyl rubber with different weight percentages (2, 4, 6, and 8 w%) was studied in laboratory scale (3.5 kg product). Butyl rubber showed the highest vibration absorption (about 27%) among the polymers studied. Generally, the higher the concentration of the polymer used, the lower tensile strength, elongation at break and also the higher of damping was obtained.
