It is heat and pressure, together with some very interesting chemistry, that makes rubber the incredibly useful engineered material we use for tire repairs. Vulcanized rubber has a stable shape which cannot be reversed providing strength and resilience. It can take repeated loads and return to its original shape even after years of use.
It won’t crumble nor deteriorate from daily exposure to moisture, chemicals, sun, or hot/cold extremes. The elastic memory ensures that sharp cuts will bounce back, becoming almost invisible. These qualities make this type of rubber very practical and beneficial for use in an industrial setting.
