LOXIOL 3366 is a fatty acid ester of a polyglycol. LOXIOL 3366 is a highly effective internal antistatic agent for several polymers, such as PVC-P, PP, S/B, PET, PBT and rubber. It reduces the surface resistance and increases the surface conductivity in these polymers. It is also suitable as an antistatic agent, viscosity regulator or plasticizer. Using higher amounts of LOXIOL 3366 allows a reduced amount of plasticizer.
