Rubber undergoes physical modification during vulcanization as a result of being forced to retract. Of course, mechanical techniques can also make rubber retract using force. But vulcanization is different since the rubber’s natural shape is preserved. Rubber shrinks during the vulcanization process while maintaining its original shape. The process of vulcanization essentially shrinks rubber without distorting or changing its shape.

Vulcanization not only modifies rubber’s size while maintaining its shape but also guards against further deformation. Rubber hardens and becomes less prone to distortion as it contracts. Vulcanized rubber won’t deform as easily as regular, non-vulcanized rubber, but it may still distort if subjected to significant stress.

When rubber is vulcanized, it also becomes harder, increasing its tensile strength and lowering the possibility of physical harm.
