Metal oxide

Properties of Vulcanised Rubber (1)

Vulcanised rubber has different characteristics from unvulcanised rubber due to the formation of cross-links during the vulcanisation process

Properties of Vulcanised Rubber (2)

The formation of sulphur cross-links reduces the double bonds between two carbon atoms in vulcanised rubber that makes it harder to be oxidised

Properties of Vulcanised Rubber (3)

Strong sulphur cross-links prevents the rubber polymer from sliding when it is stretched and can return to its original shape when released

Properties of Vulcanised Rubber (4)

Strong sulphur cross-links makes vulcanised rubber more elastic and has high heat resistance

Properties of Vulcanised Rubber (5)

The unique characteristics of vulcanised rubber allow various items to be produced compared to unvulcanised rubber.

Elasticity of vulcanised rubber compared to unvulcanised rubber

Vulcanised rubber are more elastic compared to unvulcanised rubber

Hardness of vulcanised rubber and unvulcanised rubber

Vulcanised rubber are more hard compared to unvulcanised rubber
