The blow point refers to the minimum degree of vulcanization required to eliminate the presence of bubbles generated by insufficient vulcanization within the vulcanized material at the end of the vulcanization process when vulcanizing compounds that include rubber under pressure. Measuring the blow point is very important for producing products with a short vulcanization time and no bubbles at all. This blow point varies depending on the composition of the rubber compound, the mixing method, temperature conditions, and so on, so it is necessary to measure it very frequently for quality control of vulcanized rubber products and for research and development of rubber compositions.

In the molding process of tires and belts, where rubber components and reinforcing materials are adhered together in layers and vulcanized, it is very important to confirm the adhesiveness of the components in advance. This device has been developed as a tool to easily measure the adhesive strength of components on-site and can also be applied to measure the adhesive strength of tapes and similar materials. The ambient temperature at the site changes with the seasons, which also affects adhesiveness. The Tackiness Checker allows for easy measurement of adhesive strength on-site.
