Styrene block copolymers (SBC), also called styrene copolymer adhesives and rubber-based adhesives, have good low-temperature flexibility, high elongation, and high heat resistance. They are frequently used in hot melt adhesive applications, where the composition retains tack even when solidified; however non-pressure-sensitive formulations are ...
The bonding temperature is lower than with most other HMAs, only about 50 °C (122 °F) to 70 °C (158 °F), when the adhesive behaves as a soft rubber acting as a pressure-sensitive adhesive. The surface wetting in this amorphous state is good, and on cooling the polymer crystallizes, forming a strong flexible bond with high cohesion.
Adhesives, especially SU-8 and benzocyclobutene (BCB), are specialized for production of MEMS and electronic components. [2] The procedure enables bonding temperatures from 1000 °C down to room temperature. [1] Adhesive bonding has the advantage of relatively low bonding temperature as well as the absence of electric voltage and current.
An adhesive can be formulated to maintain tack in cooler temperatures or a greater amount of adhesive coating on the tape may be necessary. The backing of the adhesives may also be plasticized in order to lower its glass transition temperature and retain its flexibility. [14]
