Vulcanized Vegetable Oil WO

Elemental sulfur is commonly used to manufacture brown vulcanized vegetable oil (WO), which is commonly used as a rubber compounding ingredient. 

WO produced from sulfur monochloride is white WO, which is more likely to be used as erasers than as a rubber compounding ingredient. This is because any residual acidity from the sulfur chloride vulcanization retards the sulfur cure of the rubber compound. Instead, the brown WO products, which are crosslinked with elemental sulfur, are commonly used as rubber compounding ingredients because they have less effect on the cure rate of the rubber compound. 

Unofficially, WO is classified by color, such as white, yellow, or brown WO. 

Commonly WO is used in rubber compounding to allow a greater quantity of process oil to be used to lower the cured compound s hardness without resulting in an oily surface exudation. WO is used in sponge rubber compounds because these compounds have to possess a low viscosity in the uncured state and be very soft in the cured state. 

There are just a few, such as art gum erasers and surface cleaning.

Other processing aids utilized in tires are vegetable oils (fatty acids, fatty acid esters/alcohols, and metal salts of these oils), naturally occurring resins such as pine tar, hydrocarbon resins from petroleum stUlbottoms, and vulcanized vegetable oils (WOs). WOs were utilized heavily in the early 1900s, but are no longer used extensively in tires. 

Sulfur reacts with chlorine to form sulfur monochloride (SjClj), which is used to synthesize DTDM (sulfur donor for efficient cures), alkyl phenol disulfide (accelerator), and vulcanized vegetable oil (WO), which is used as a processing aid for rubber.
