It has good dispersibility! It is a curing agent suitable for both high and low sulfur content (EV vulcanization).
"VULCAR" is a polymer polysulfide-based vulcanizing agent uniquely developed by Toyo Chemical to resolve poor dispersion of sulfur and blooming. In sulfur vulcanization, sulfur is an indispensable vulcanizing agent; however, sulfur and insoluble sulfur (Su) have poor compatibility with rubber, leading to poor dispersion and blooming, which not only diminishes product value but also significantly reduces vulcanized properties. This product has a molecular structure that enhances compatibility at a low melting point (69-72°C), resulting in good dispersion and eliminating concerns about blooming. Therefore, it is a vulcanizing agent suitable for both high and low sulfur content (EV vulcanization). **Features** - Low melting point (69-72°C) - Molecular structure that enhances compatibility - Good dispersion - No concerns about blooming *For more details, please refer to the PDF document or feel free to contact us.*
