Tire Release

Green tire curing is performed in heating presses, usually equipped with metal molds to shape the tires' outsides during vulcanization, and inflatable rubber bladders to shape the inside of the green tires and press the tires against the metal mold.

At the interface of the tire/ inflatable rubber bladder, the release is critical: without the use of a release agent, tire rubber and bladder rubber would certainly stick together after curing.

Multi-Release

A multi-release agent is applied on the inside of the green (uncured) tire. This side is going to be in contact with the inflatable bladder. The green tire (uncured) is then placed in the cavity of the heating press. The mold closes and the bladder starts to inflate.
