CAS 140-93-2 is the chemical identifier for dioctyl phthalate (DOP), a commonly used plasticizer. DOP is a clear, colorless liquid mainly used to soften and increase the flexibility of polyvinyl chloride (PVC) materials. It is a high-molecular-weight phthalate ester with excellent processing properties at room temperature. DOP is compatible with many different substances, making it an essential ingredient in numerous industrial and consumer applications. It is particularly useful in the production of cling wraps, vinyl flooring, cable and wire insulation, and inflatable products. Additionally, DOP can be used as a solvent in various industrial processes, and a lubricant in metalworking applications. Due to its unique properties, DOP has become one of the most widely used plasticizers in the world. Its demand continues to grow across industries requiring flexible, durable, and weather-resistant plastics. Moreover, DOP is available in various grades, each with specific properties and characteristics. This wide range of options allows manufacturers and formulators to tailor DOP to fit their specific requirements. Overall, DOP is a versatile and integral ingredient in many industrial and consumer applications that require plasticized materials. Its ability to enhance the flexibility and processing characteristics of PVC has made it an essential component of numerous products and industrial processes.
