BEIJING, May 14, 2026 Thermoplastics, as high-molecular-weight materials, feature high melt viscosity and require processing under melting and shearing conditions. Reducing melt viscosity is critical to boost productivity, minimize machinery wear and cut energy consumption. Lubricants are key additives that enhance melt flow, reduce adhesion to equipment, and also act as melting accelerators, anti-blocking agents, antistatic agents, and modifiers for color and impact performance. Lubricant molecules contain long non-polar and polar groups, split into internal and external types. Internal lubricants improve polymer flow by weakening intermolecular forces. External lubricants migrate to the surface to reduce friction, prevent melt fracture and aid demolding. Most products offer combined effects. Common types include hydrocarbons, fatty acids, esters, amides, alcohols, silicone oils and metal soaps. Stearic acid and stearamide are widely used in VOC testing, mainly derived from animal and vegetable oils. Modern industry prioritizes green, high-performance additives. Advanced lubricant innovations drive plastics processing toward lower energy use, higher quality and eco-friendliness, supporting packaging, automotive, electronics and other manufacturing sectors.
