Brabender Plastgraph Kneading Characteristics

The kneading characteristics of SEKISUl PVC-HA in terms of Brabender Plastgraph are shown in Chart 1. As can be seen the gelation proceeds quicker than PVC. The kneading torque also rises high except in the case of high liquidity grades. Therefore, when molding, it is necessary to pay special consideration to the molding conditions such as special compounding for a better lubricity and higher molding temperature.
