NINGBO INNO PHARMCHEM CO.,LTD. is pleased to announce the availability of its high-quality Dioctyl Terephthalate, commonly known as DOTP. This advanced plasticizer is a key component in the production of flexible polyvinyl chloride (PVC) products, offering a superior environmental profile and performance characteristics compared to traditional plasticizers.

DOTP is chemically defined as the diester of terephthalic acid and the branched-chain 2-ethylhexanol. Its CAS number is 6422-86-2, and its chemical formula is C24H38O4. As a transparent liquid, DOTP serves as an excellent softening agent for PVC, facilitating its processing and enhancing its physical properties. Unlike many conventional plasticizers, DOTP is a non-phthalate compound, addressing growing concerns regarding the use of ortho-phthalates in various applications. This makes it a preferred choice for manufacturers seeking to comply with stringent environmental and health regulations globally.

The performance benefits of NINGBO INNO PHARMCHEM's DOTP are numerous and significant. One of its most outstanding features is its environmental performance. Being a non-phthalate, it is considered safer with an excellent toxicological profile, suitable for sensitive applications like medical consumables, children's toys, and food contact materials (where applicable regulations permit). This aligns with the increasing consumer and regulatory demand for safer and more sustainable materials.

DOTP exhibits excellent heat resistance and cold resistance. In high-temperature environments, it maintains its integrity, showing low volatility and resistance to decomposition, which helps preserve the stable physical properties of the finished PVC product. Conversely, at low temperatures, it enhances the flexibility of PVC, preventing it from becoming brittle and cracking. This broadens the operational temperature range of materials plasticized with DOTP, making it ideal for products like hoses used in diverse climates.

Another critical property is low volatility. This ensures that the plasticizer remains within the PVC matrix over the product's lifespan, reducing emissions and maintaining flexibility and durability. Lower volatility also contributes to a more stable working environment during processing.

The low migration characteristic of DOTP is particularly beneficial. Due to its chemical structure, it is less prone to migrating out of the PVC material compared to some phthalate-based plasticizers. This resistance to migration prevents the finished product from becoming stiff or brittle over time and reduces interaction with surfaces or other materials it comes into contact with. For example, in hoses or cables, low migration helps prevent the material from sticking to other components or surfaces, ensuring long-term performance and aesthetics.

DOTP imparts good flexibility and extraction resistance to PVC. Its linear structure contributes to better low-temperature flexibility, reducing the material's fragility in colder conditions. This makes products like hoses easier to handle and bend without damage. The resistance to extraction means the plasticizer is less likely to be removed by exposure to water, oils, or other substances, maintaining the material's softness and flexibility.

Furthermore, NINGBO INNO PHARMCHEM's DOTP provides good softness and excellent electrical insulation properties. These characteristics are vital for applications such as electrical cables and wires, where both flexibility for installation and reliable insulation are paramount.

The use of DOTP also results in stable plastisol viscosity. For manufacturers utilizing plastisol processes, the ability of DOTP to maintain a stable viscosity over time is a significant advantage, leading to uniform product thickness and consistent processing results.

NINGBO INNO PHARMCHEM CO.,LTD. supplies DOTP meeting stringent quality indicators. Our top-grade product boasts an ester content of ≥99.5%, an acid value of ≤0.02 mg KOH/g, and a flash point of ≥210°C.
