Understanding The Rubber Manufacturing .

The rubber may contract or expand during the process. Also note that the length of the rubber is also impacted after vulcanization. Meanwhile, the extrusion process is suitable for producing rubber in high volumes and the cost is also affordable. The products produced during the extrusion process include gaskets, tubing, cord and profiles.
