Siping is a process of cutting thin slits across a rubber surface to improve traction in wet or icy conditions. Siping was invented and patented in 1923 under the name of John F. Sipe . [ 1 ] [ 2 ] The story told on various websites is that, in the 1920s, Sipe worked in a slaughterhouse and grew tired of slipping on the wet floors.
The first commercial use of siping was a year earlier, where Tecalemit used a knife-cutting process almost identical to Sipe's original patent as a means of recutting worn treads. Europe also abandoned the slow process of literally knife cutting in favour of steel blades in the tread moulds, forming the sipes by moulding.
In its uncured state, silicone rubber is a highly adhesive gel or liquid. To convert it to a solid, it must be cured, vulcanized, or catalyzed. This is normally carried out in a two-stage process at the point of manufacture into the desired shape, and then in a prolonged post-cure process. It can also be injection molded or 3D printed.
Worker placing a tire in a mold before vulcanization. Vulcanization (British English: vulcanisation) is a range of processes for hardening rubbers. [1] The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice.

The first Yeti coolers arrived in America in the spring of 2008. They had spent weeks at sea, traveling from a factory in the Philippines to a leased warehouse in the hills south of Austin, Texas.
Styrene-butadiene or styrene-butadiene rubber (SBR) describe families of synthetic rubbers derived from styrene and butadiene (the version developed by Goodyear is called Neolite [1]). These materials have good abrasion resistance and good aging stability when protected by additives.
Rubber tapping in Indonesia, 1951. Rubber tapping is the process by which latex is collected from a rubber tree.The latex is harvested by slicing a groove into the bark of the tree at a depth of one-quarter inch (6.4 mm) with a hooked knife and peeling back the bark.
