| Use | spices; Food packaging materials. The product is a variety of resin processing lubricant, non-toxic, with waterproof and good thermal stability. Mainly used for PVC transparent soft and hard extrusion, injection molding, calendering products, the amount of 0.5-1. The product is also very effective for the processability of modified vinyl chloride-vinyl acetate copolymer, polystyrene, nitrile rubber, etc. It can also be used as a lubricant for fabrics, a water repellent, an additive for lubricating oils, a base for cosmetics, and the like. suitable for PVC transparent products and pipes, used as internal lubricant for resin processing used as lubricant. Solvent. Dispersants and softeners for plastics |
| production method | stearic acid and butanol are esterified by sulfuric acid catalysis, and then dealcoholized at high temperature and reduced pressure, after washing with water and pressure filtration, the finished product is obtained. The yield (calculated as stearic acid) was 87%.
