In the world of polymer science and material engineering, plasticizers play a pivotal role in transforming rigid polymers into flexible, versatile materials. Among the array of plasticizers available, Dicotyl Terephthalate (DOTP), identified by its CAS number 6422-86-2, stands out as a high-performance primary plasticizer, particularly valued for its application in Polyvinyl Chloride (PVC) formulations.

DOTP is an ester of terephthalic acid and 2-ethylhexanol. Its molecular structure grants it a combination of properties that make it a preferred alternative to traditional plasticizers like Di-Octyl Phthalate (DOP) in many applications. NINGBO INNO PHARMCHEM CO.,LTD. recognizes the increasing demand for efficient and reliable plasticizers like DOTP and is committed to providing a product that meets stringent quality standards.

One of the most significant advantages of DOTP is its excellent performance characteristics. It is widely recognized for its superior low temperature resistance, allowing flexible PVC products to maintain their flexibility and integrity even in cold environments. This property is crucial for applications such as electrical cables and wires used outdoors or in unheated spaces, preventing brittleness and cracking.

Furthermore, DOTP offers remarkable thermal stability. This means that during the processing of PVC at elevated temperatures, DOTP remains stable, contributing to the longevity and durability of the final product. It also ensures that the plasticized material can withstand exposure to heat during its service life without significant degradation.

Another key benefit is its strong extraction resistance. Products plasticized with DOTP exhibit low volatility and migration, meaning the plasticizer is less likely to leach out over time when exposed to various media such as water, oils, or solvents. This feature is particularly important for applications requiring cleanliness and stability, such as flooring, wall coverings, and certain types of films.

DOTP also boasts high plasticizing efficiency, meaning that relatively lower concentrations are needed to achieve the desired flexibility compared to some other plasticizers. This can translate into cost savings and potentially improved mechanical properties in the final product.

The versatility of DOTP makes it suitable for a wide range of flexible PVC applications beyond just cables. It is effectively used in calendared films, extruded profiles, injection molded articles, and plastisols (PVC pastes). For plastisols, DOTP helps in lowering viscosity and maintaining long-term storage stability, which is essential for various coating and dipping processes.

Quality is paramount when sourcing chemical raw materials. High-purity DOTP, typically exceeding 99% ester content, ensures consistent performance and prevents unwanted side reactions or impurities affecting the final product. Key technical parameters like acid value, flash point, density, and color are critical indicators of quality that should be carefully controlled and verified.

NINGBO INNO PHARMCHEM CO.,LTD. maintains a rigorous quality control process to ensure that its DOTP meets premium standards. From raw material sourcing to final product inspection, every step is monitored to guarantee purity, consistency, and performance.

Packaging and logistics are also crucial aspects of supplying bulk chemicals. DOTP is commonly transported in various formats, including 200kg drums, 1000kg or 1150kg IBC drums, or 22mt flexitanks, offering flexibility depending on the customer's needs and infrastructure. Efficient and safe transportation is essential to ensure the product arrives in perfect condition.

For businesses looking to buy or purchase Dicotyl Terephthalate, finding a reliable manufacturer or supplier is a critical step. A reputable partner can provide technical support, consistent product quality, and reliable delivery. Pricing for bulk chemicals like DOTP typically varies based on order volume, market conditions, and packaging requirements. Obtaining a competitive price requires engaging directly with suppliers who understand your specific needs and can offer flexible solutions.

NINGBO INNO PHARMCHEM CO.,LTD. offers competitive pricing structures for various order sizes and is equipped to handle national and international shipments, adhering to relevant certifications like REACH for certain markets and maintaining standardized quality management systems such as ISO 9001. Businesses interested in obtaining samples or discussing their specific requirements are encouraged to contact a trusted supplier to explore procurement options and secure a consistent supply of high-quality DOTP for their manufacturing processes.
