At first, it wasn't invented at all. It was harvested from the rubber tree in Brazil (Hevea Brasiliensis). Synthetic rubber came later (made from petroleum products).
rubber processing oil is used as a lubricator in tyre industry and as a raw material for plastic, chemical and rubber industry.

Vulcanization is a chemical process for converting rubber into more durable materialsby adding sulfur. Non-vulcanized (uncured) natural rubber is sticky, deforms easily when warm, and is brittle when cold. Vulcanized rubber is less sticky and have superior mechanical properties compared to non-vulcanized rubber.Such as:better weather resistance (sunlight, temperature changes, water and snow)better durability (stands mechanical wear better)better elasticitybetter mold ability (easier to make things out of)
Dividing weight by volume . W/v - kg/m3.
the answer before this was wrong, rubber was invented in Woburn, Massachusetts.
=The rubber band was invented to hold pappers and envelopes.=
goodrich Charles Goodyear invented the process for making rubber that he named vulcanization. Goodrich then made the rubber last longer by adding carbon. Goodrich also invented synthetic rubber.
Charles Goodyear invented the process to vulcanize rubber in 1839.
