A typical PSA tape consists of a pressure-sensitive adhesive (the sticky part of the tape) coated to a backing material. To prevent the adhesive from sticking to the backing when wound in a roll, a release agent is applied to the backing or a release liner is placed on the adhesive.
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 ...
At that time, stamp adhesives consisted of naturally occurring raw materials such as molasses, potato starch and occasionally fish glue, but these performed poorly. So, the stamps either stuck together or fell off prematurely and emitted an unpleasant odour. In addition, the stamps had to be moistened before fixing, which was often done by licking.
Rubber elasticity is the ability of solid rubber to be stretched up to a factor of 10 from its original length, and return to close to its original length upon release. This process can be repeated many times with no apparent degradation to the rubber. [1] Rubber, like all materials, consists of molecules.
It is known colloquially among chemists as the "Rubber Bible", as CRC originally stood for "Chemical Rubber Company". [2] As late as the 1962–1963 edition (3604 pages), the Handbook contained myriad information for every branch of science and engineering. Sections in that edition include: Mathematics, Properties and Physical Constants ...
With modern laser-engraving technology, personalized rubber stamps can be made in minutes. Rubber stamps for business commonly show an address, corporate logo and business registration number. [5] [6] Some stamps also have movable parts that allow the user to adjust the date or the wording of the stamp. They are used to date incoming mail, as ...
Silicone rubber is used as an electrical insulator in power cables and cable joints. [18] [21] Silicone-insulated cables are advantageous in that they can withstand temperatures from -90°C to 200°C, and are highly flexible. These properties make them suitable for maintaining circuit integrity in the event of a fire. [22]
In continuum mechanics, an Arruda–Boyce model [1] is a hyperelastic constitutive model used to describe the mechanical behavior of rubber and other polymeric substances. This model is based on the statistical mechanics of a material with a cubic representative volume element containing eight chains along the diagonal directions.
