For example, a scorch time at ambient temperature indicates the rubber will be able to remain unvulcanized at room temperature for an extended period of time.

So I think the black patch is vulcanized rubber and the orange layer is unvulcanized rubber : vulcanized rubber will deform elastically so return to its original form after stretching, the unvulcanized will deform plastically and be longer after stretching.

I assume unvulcanized rubber is used precisely because it's plastic instead of elastic : it will take on the shape of the tire surface, and keep that shape after vulcanization . talk ) 16 : 42, 1 December 2013 ( UTC)
