About This Product

■Features

VULCAR is a "polymer polysulfide vulcanizing agent" originally developed by Toyo Kagaku Co., Ltd. to eliminate poor sulfur dispersion and blooming. Sulfur is an indispensable vulcanizing agent in sulfur vulcanization, but sulfur and insoluble sulfur (Su) have poor compatibility with rubber, causing poor dispersion and blooming, which not only impairs commercial value, but also inhibits vulcanization. It will significantly reduce the physical properties. VULCAR has a molecular structure that has a low melting point (69-72℃) and good affinity for polymers that can be sulfur-vulcanized, so it has excellent dispersibility. It's good and you don't have to worry about blooming. Therefore, it is a vulcanizing agent suitable for both high and low sulfur content (EV vulcanization).

■Handling precautions

・Although bulker does not fall under the Fire Service Act's Hazardous Materials: Class 2 (Sulfur) and Class 4 (Class 3 Petroleum), it is a sulfur compound, so please handle it accordingly. In particular, please refrain from using fire. ・Since VALQUA is a polymeric polysulfide vulcanizing agent with a low melting point (starts to melt from 69.0℃), when kneading with rolls, the optimum kneading temperature is 70 to 80℃. ・Please refer to the Material Safety Data Sheet (MSDS) for other information on bulker handling and storage methods.
