For manufacturers in the PVC industry, selecting the right plasticizer is a critical decision that impacts product quality, processing efficiency, and market competitiveness. Dioctyl Terephthalate (DOTP), also known by its CAS number 4654-26-6, has emerged as a leading choice due to its exceptional characteristics and phthalate-free nature. As a dedicated manufacturer and supplier in China, we are pleased to offer insights into this versatile chemical auxiliary.

DOTP is a colorless, transparent liquid with a molecular formula of C24H38O4. Its key technical specifications, such as a purity of 99.5%, an acid value of ≤ 0.05 mgKOH/g, and a flash point of ≥ 210°C, underscore its high quality and suitability for demanding applications. Unlike traditional ortho-phthalate plasticizers, DOTP offers a significantly improved health and environmental profile. This makes it an increasingly sought-after ingredient, especially in markets with stringent safety standards.

The performance advantages of DOTP are numerous. Its high plasticizing efficiency allows for effective modification of PVC's mechanical properties, contributing to enhanced flexibility and processability. Manufacturers can achieve desired material characteristics with a lower addition rate, potentially optimizing production costs. Furthermore, DOTP exhibits low volatility, which is crucial for the longevity and stability of finished PVC products. This means less material is lost during processing and the end product retains its desirable properties for longer periods.

When considering the price for DOTP, partnering with a reputable Chinese supplier like us ensures competitive rates without compromising on quality. We understand the importance of a reliable supply chain for our B2B clients, enabling them to maintain consistent production schedules and meet market demands.

The applications of DOTP are diverse and continue to expand:

  • Electrical Cables: Its excellent electrical insulation properties and resistance to high temperatures make it ideal for PVC cable sheathing and wire insulation, conforming to international standards.
  • Artificial Leather: DOTP imparts a soft feel and good durability to synthetic leather products, used in upholstery, apparel, and automotive interiors.
  • Flooring and Wall Coverings: The plasticizer enhances the wear resistance and flexibility of PVC flooring and decorative wall panels.
  • Films and Sheets: DOTP is used to produce flexible PVC films and sheets for packaging, stationery, and protective coverings.
  • Coatings and Inks: It contributes to the flexibility and adhesion of various coating formulations and printing inks.
