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.
