Polyimide Tape — Silicone vs. Acrylic Adhesive

Gen­er­al­ly speak­ing, the acrylic adhe­sive will have high­er adhe­sion at mid-range tem­per­a­tures (0°C to 100°C), but sil­i­cone adhe­sives have high­er adhe­sion at low­er tem­per­a­tures (under 0°C) and high­er tem­per­a­tures (above 100°C). This adhe­sion is inde­pen­dent of the tape thick­ness (1mil, 2mil or 5mil) as the adhe­sive lay­er thick­ness remains con­stant. This is sub­strate depen­dent and oth­er vari­ables can come into play, but this is a good rule of thumb.

Sil­i­cone-based adhe­sives are cer­tain­ly more stan­dard, but some­times the cus­tomer needs acrylic because they can­not have sil­i­cone in their sys­tems, need high­er adhe­sion at mid-range tem­per­a­tures or oth­er spe­cif­ic rea­sons.
