Esmarch bandage (also known as Esmarch's bandage for surgical haemostasis or Esmarch's tourniquet) in its modern form is a narrow (5 to 10 cm (2.0 to 3.9 in) wide) soft rubber bandage that is used to expel venous blood from a limb (exsanguinate) that has had its arterial supply cut off by a tourniquet. The limb is often elevated as the elastic ...

A rubber band ball is a sphere of rubber bands made by using a knotted single band as a starting point and then wrapping rubber bands around the center until the desired size is achieved. The ball is usually made from 100% rubber bands, but some instructions call for using a marble , [ 16 ] a crumpled piece of paper , or a ping-pong ball [ 17 ...
In ancient Mesoamerican cultures, rubber was used to make balls, sandal soles, elastic bands, and waterproof containers. [4] It was cured using sulfur-rich plant juices, an early form of vulcanization. [5] In the 1830s, Charles Goodyear worked to devise a process for strengthening rubber tires. Tires of the time would become soft and sticky ...
A rubber band is a single molecule, as is a latex glove. The sections of polyisoprene between two adjacent cross-links are called network chains and can contain up to several hundred isoprene units. In natural rubber, each cross-link produces a network node with four chains emanating from it.

EPDM rubber (ethylene propylene diene monomer rubber) [1] [2] [3] is a type of synthetic rubber that is used in many applications. EPDM is an M-Class rubber under ASTM standard D-1418; the M class comprises elastomers with a saturated polyethylene chain (the M deriving from the more correct term polymethylene).
Elastic bandages are also used to treat bone fractures. Padding is applied to the fractured limb, then a splint (usually plaster) is applied. The elastic bandage is then applied to hold the splint in place and to protect it. This is a common technique for fractures which may swell, which would cause a cast to function improperly.
