Pure acrylics have a lower tack (“stickyness when dry” for the layman) and less adhesion on hard-to-bond plastics such as high- and low-density polyethylene (HDPE & LDPE) and polypropylene (PP) than modified acrylic or rubber adhesives. Pure acrylic adhesives are mainly used on tapes whose applications are bonding, sealing or surface protection.
3M also makes an electrical tape made of silicone rubber for applications where Class “H” (180°C/356°F) temperatures are encountered i.e., silicone rubber cables.
