A review of pressure‐sensitive adhesives (PSAs) and PSA tapes is presented. Typical constructions of PSA tapes are discussed along with a short section on the release surfaces used in conjunction with most PSAs. A discussion of the physical properties governing PSA performance is provided with emphasis on the effect of the viscoelastic nature of PSAs on adhesion. The most common types of tapes—industrial, consumer and office, medical, and labels—are described along with reference to other specialty constructions. Test methods, including peel, tack, shear, and rheology, are described for PSA tapes. Sections describing the most common materials used as PSAs—block copolymers, natural rubber, and acrylics—are included along with short descriptions of silicones, polyisobutylene, and polyolefins. A short section on general manufacturing methods of PSAs and PSA tapes is also included.
