LOXIOL VPG 861

LOXIOL VPG 861 is a long-chain ester of pentaerythritol that acts as a processing agent for various types of thermoplastics used in advanced materials. In the injection molding of polycarbonate, PET, PBT, PMMA, and polyacetal, LOXIOL® VPG 861 prevents polymer melt from sticking to hot machine parts and aids mold release at high temperatures. This allows for the use of complex mold geometries. Additionally, it improves feed behavior and prevents granules from melting in the feed zone. LOXIOL® VPG 861 enhances tool filling speed, improving the surface properties of finished articles. Polycarbonate and PMMA containing 0.1% to 0.5% of LOXIOL® VPG 861 remain transparent and color stable. It can also be used as an antiblock additive in biaxially oriented polyester films, enhancing abrasion resistance. Typical dosages range from 0.2% to 1.0%, depending on its use as an internal or external lubricant.
