Blow Point Tester | 642

ModelNo. 642

Toyo Seiki · Curing Properties / Mooney Viscosity

When a rubber-laden composite material is vulcanized under pressure, bubbles are generated within the material due to insufficient vulcanization in the final phase of the process. The blow point stands for the minimum vulcanization level required for eliminating the existence of these bubbles. To make a product with no bubbles in a shorter time of vulcanization, it is very important to measure the blow point.
