For procurement managers tasked with sourcing essential chemical raw materials, the selection of a high-quality Dioctyl Terephthalate (DOTP) is critical for ensuring the performance and safety of their end products. DOTP (CAS 6422-86-2) has become a preferred plasticizer due to its favorable environmental profile and excellent performance characteristics, offering a viable alternative to regulated phthalates. Navigating the global chemical market, especially from China, requires a clear understanding of product specifications, supplier reliability, and pricing dynamics. NINGBO INNO PHARMCHEM CO.,LTD. offers insights into sourcing this vital chemical.

Understanding DOTP Specifications for Procurement

When you buy Dioctyl Terephthalate, several key specifications should be scrutinized to ensure it meets your application requirements:

  • Purity: Look for DOTP with a high purity level, typically 99.5% or higher for superior performance in demanding applications like wire and cable. A certificate of analysis (COA) detailing assay results is essential.
  • Appearance: DOTP should be a clear, colorless viscous liquid. Any discoloration or presence of particulate matter could indicate contamination or degradation.
  • Key Physical Properties: Important parameters include density (around 0.983-0.988 g/cm³ at 20°C), refractive index (around 1.487-1.492), flash point (typically >210°C), and acidity (low, usually <0.02%).
  • Non-Phthalate Certification: For compliance and market access, ensure the DOTP is explicitly identified as a non-phthalate plasticizer.

Applications and Their DOTP Requirements

DOTP's versatility allows its use across various sectors. Procurement managers need to match DOTP grades to specific application needs:

  • PVC Applications (Flooring, Films, Artificial Leather): Standard industrial grades of DOTP are generally sufficient, prioritizing cost-effectiveness and consistent flexibility.
  • Wire and Cable Insulation: Higher purity DOTP with excellent electrical properties and thermal stability is crucial. Suppliers offering DOTP specifically for cable insulation ensure better performance and safety.
  • Automotive Components: DOTP used in automotive interiors requires good UV resistance, low fogging, and long-term durability.
  • Medical Devices: For medical applications, strict adherence to biocompatibility standards and very high purity levels of DOTP are mandatory.

Identifying a Reliable DOTP Supplier in China

When sourcing from China, establishing a relationship with a reputable DOTP manufacturer or distributor is key. Consider these factors:

  • Production Capacity and Lead Times: Ensure the supplier can meet your volume requirements and has reliable production and delivery schedules.
  • Quality Control and Certifications: Look for ISO certifications and a transparent quality control process, including readily available COAs for each batch.
  • Technical Support and Customer Service: A supplier that can offer technical guidance and responsive customer service can be invaluable in resolving any formulation or supply chain issues.
  • Pricing and Payment Terms: Obtain competitive quotes and understand the payment terms. While price is important, it should not compromise quality or reliability.
