Elastomer

Listing ID #3481930

The first stage is the mixing compounding stage where the elastomer is mixed with various additives such as re-enforcing agents, softeners, pigments, curing agents, antioxidants and processing aids. The mixing occurs in a dispersion kneader which mixes the ingredients under high pressure, controlled high temperature and preset mixing times. All the ingredients are combined to form compound lumps which are dumped out of the dispersion kneader. The lumps are cooled and aged for a few days in order to improve final properties of the component. These compound lumps are then mixed on a two-roll mixing mill. Curing agents such as sulphur or peroxides are added on the two roll mill and compound is milled till it is homogeneous. The compound is then taken out as sheets in the required thickness. The thickness of the compound sheet can be adjusted in the two-roll mixing mill. This compound sheet is now sent for moulding extrusion.
