Behind almost every industrial tape and release liner sits one of two adhesive chemistries: acrylic or silicone. Choosing between them early in a project prevents expensive redesigns later, so it is worth understanding where each system wins.

Acrylic adhesives are the workhorse of general industrial bonding. They offer strong, stable adhesion to metals, glass, paper and most plastics, excellent aging resistance, and a cost profile that supports high-volume converting. Acrylic systems coat cleanly at high line speeds and are the default choice for protective films, general-purpose double-sided tapes and most die-cut gaskets. Their limits appear under sustained heat — typically becoming the deciding factor above 120 °C — and on low-surface-energy substrates.

Silicone adhesives occupy the demanding end of the spectrum. They maintain performance where acrylics cannot: continuous high-temperature processes, PTFE and other release surfaces, silicone-elastomer laminates, and applications that demand clean removal after thermal cycling. Silicone pressure-sensitive systems also pair naturally with silicone release liners, giving stable release force for precision die-cutting. The trade-offs are higher material cost and a more specialized coating process.

A practical decision path: define your maximum service temperature, your substrate surface energy, and your removal requirements. If all three sit in the moderate range, acrylic will almost always deliver equal or better value. If any one of them is extreme — long exposure above 120 °C, a silicone or PTFE surface, or residue-free removal after heat — move to silicone.

ORISUN manufactures both families on dedicated lines, including PET silicone oil films, silicone-coated release liners and high-temperature masking solutions, alongside a full acrylic tape portfolio.
