Modification of styrene butadiene rubber (SBR)/natural rubber (NR) system using oil tackifier for pressure sensitive adhesive / Amirah Wahid

Pressure Sensitive Adhesive (PSA) tape is where surfaces can be adhered to tenaciously upon application only with a light finger pressure. Strength of the bond is influenced by the contact pressure .This PSA is ease of application and have ability to be removed cleanly from surfaces on which they are applied. It's actually composed of a rubbery tape elastomer combined with a liquid or solid resin tackifier component. In this study EPS was used together with SBR and incorporation with NR also aid from ESO to make a new formulation of PSA. Two formulations were created because used the different type of NR which are SBR/ENR EPS and SBR/SMRL EPS adhesives. The combination of SBR is to improved the compatibility between EPS and NR but due to the separation layer of the mixing , then SMRL also ENR was used to overcome this problem By using these type of rubber also indirectly improved the tackiness of the adhesives. ESO was using in order to make the bonding of the adhesives onto substrate more strength. However the highest of incorporation ESO (6%) will give decreases in shear strength value.
