What is the adhesive on Scotch tape made out of?

The question is in the title.

Which kind? Magic tape? Transparent? Acid-free? They have more kinds of tape than you can shake a stick at. I don't know what's in any of their adhesives.

See Pressure-sensitive adhesive

Composition

PSAs are usually based on an elastomer compounded with a suitable tackifier (e.g., a rosin ester). The elastomers can be based on:

Acrylics, which can have sufficient tack on their own to not require a tackifier. Bio-based acrylate. Recently, a biological-based macromonomer was grafted onto a backbone of acrylate so that the resulting PSA uses 60% bio-based materials.[1]

Butyl rubber

Ethylene-vinyl acetate (EVA) with high vinyl acetate content; can be formulated as a hot-melt PSA.

Natural rubber

Nitriles

Silicone rubbers, requiring special tackifiers based on "MQ" silicate resins, composed of a monofunctional trimethyl silane ("M") reacted with quadrafunctional silicon tetrachloride ("Q").

Styrene block copolymers (SBC), also called styrene copolymer adhesives and rubber-based adhesives, have good low-temperature flexibility, high elongation, and high heat resistance.

Styrene-butadiene-styrene (SBS), used in high-strength PSA applications

Styrene-ethylene/butylene-styrene (SEBS), used in low self-adhering non-woven applications

Styrene-ethylene/propylene (SEP)

Styrene-isoprene-styrene (SIS), used in low-viscosity high-tack PSA applications

Vinyl ethers

■Transparent office tape has a transparent film backing and an acrylic or synthetic rubber based adhesive. It is used for sealing envelopes, repairing torn paper products, general holding, etc.

Then why did you ask which kind?
