Autoclave expansion is the most common route the bead foam. [4] Butane or pentane is often used as a blowing agent (before 1992 CFCs may have been used). Depending on the specific process uses the beads may be cross-linked either by electron beam irradiation (see Electron beam processing), or by the addition of a chemical agent such as dicumyl ...
They can also be used as a lightweight filler in e.g. cultured marble, waterborne paints and crack fillers/joint compound. Expandable polymer microspheres can expand to more than 50 times their original size when heat is applied to them. The exterior wall of each sphere is a thermoplastic shell that encapsulates a low boiling point hydrocarbon.
Extensibility is a software engineering and systems design principle that provides for future growth. Extensibility is a measure of the ability to extend a system and the level of effort required to implement the extension.
Expandable tubular technology is a system for increasing the diameter of the casing or liner of an oil well by up to 30% after it has been run down-hole. Telescoping well design [ edit ]
Thermal expansion is the tendency of matter to increase in length, area, or volume, changing its size and density, in response to an increase in temperature ...
An expendable launch system (or expendable launch vehicle/ELV) is a launch vehicle that can be launched only once, after which its components are destroyed during reentry or impact with Earth, or discarded in space.
An expandable baton (also referred to variously as a collapsible baton, telescopic baton, tactical baton, spring cosh, ASP, or extendable) is typically composed of a cylindrical outer shaft containing telescoping inner shafts (typically 2 or 3, depending on the design) that lock into each other when expanded. The shafts are usually made of ...
ASP 21-inch (530 mm) tactical baton in expanded and collapsed states. ASP manufactures telescopic batons. [1] ASP batons have been adopted by law enforcement agencies in the United States, United Kingdom, Canada, New Zealand and Australia, and expandable batons are sometimes referred to as "Asps".
