Straksa i pas wantaim:Linear molecules are connected to each other by the bridging of some atoms or clusters of atoms to form a three-dimensional network structure. This structure is strengthened as the vulcanization process progresses. In this way, the free mobility of the segments decreases, the plasticity and elongation decrease, the strength, elasticity and hardness increase, and the compression set and swelling decrease.
