PELESTAT 300 is a polyether-polyolefin block copolymer that offers long-lasting electrostatic dissipation immediately after molding when used in the production of polyolefins, such as polyethylene and polypropylene. It ensures no degradation of the physical properties or moldability of polyolefins upon blending and can be easily combined, ensuring optimal performance in the production of electric appliances, floor materials, electronic parts, automobile interiors, and more. Due to its dispersibility with base resins, it can be dry blended with polyolefins prior to molding via injection, extrusion, or calendar molding processes, avoiding the need for excessive kneading processes. With low dependence on humidity, this anti-static agent exhibits immediate static prevention and antifouling properties, with very little change after contact with water.
