Stearic Acid used as a mold release reagent in the plasticy industry

Stearic Acid used as a mold release reagent in the plasticy industry

In the processing of PVC films, stearic acid is not only an effective heat stabilizer but also can prevent the film from discoloring when exposed to sulfide environments, ensuring the appearance quality and service life of the film. In addition, in the processing of other plastic varieties such as polyethylene and polypropylene, stearic acid can also be used as a lubricant and mold release agent to improve processing performance and product quality.

Tallow Distilled Fatty Acid Industrial Grade used as raw materials for the synthesis of engineering plastics in the plastic industry

Tallow Distilled Fatty Acid Industrial Grade used as raw materials for the synthesis of engineering plastics in the plastic industry

Plasticizers and Lubricants: Industrial-grade tallow distilled fatty acids can be used as plasticizers and lubricants for plastics such as polyvinyl chloride (PVC) and polystyrene (PS). As a plasticizer, it can reduce the force between plastic molecules, increase the flexibility, ductility, and plasticity of plastics, making plastics easier to process and form. As a lubricant, it can reduce the friction between plastics and equipment during processing, reduce processing energy consumption, improve processing efficiency, and improve the surface finish and demolding performance of plastic products. (2)Stabilizers: In the processing of PVC plastics, when used in combination with stabilizers such as metal soaps, it can improve the thermal stability and light stability of PVC, prevent PVC from aging, discoloration, embrittlement, etc. due to heat and light during processing and use, and extend the service life of plastic products.

High Iodine Value Oleic Acid IV140, which is used as an additive for engineering plastics in the plastic industry

High Iodine Value Oleic Acid IV140, which is used as an additive for engineering plastics in the plastic industry

In industrial-grade mixed oils, the addition of high iodine oleic acid IV140 can increase the unsaturation of the mixed oil, thereby influencing some properties of the mixed oil. For example, it reduces the solidifying point of the mixed oil, enabling better fluidity at low temperatures; it also improves the oxidative stability and reaction activity of the mixed oil, making it more suitable for industrial application scenarios with special requirements for oil properties.

Refined Oleic Acid IV130, which is used as a plasticizer in the plastic industry

Refined oil acid IV130 serves as a vital additive in the plastic industry. As a plastic plasticizer, it significantly enhances the flexibility, ductility, and processing performance of plastics like polyvinyl chloride (PVC) and polystyrene (PS), reducing their hardness and brittleness. This makes it ideal for manufacturing plastic products such as films, hoses, and artificial leather. Additionally, in engineering plastic production, it acts as a lubricant to minimize friction between plastic particles during processing, improving molding efficiency and product quality.
