Features Of UPC UniHydro UN488 Dioctyl Terephthalate Plasticizer

  1. High molecular weight ester offering excellent volatility resistance and low migration in demanding applications.

  2. Superior thermal and UV stability compared to conventional phthalate plasticizers, supporting long-term performance in outdoor-use compounds.

  3. Low temperature flexibility retention with balanced processing viscosity for efficient extrusion and calendering operations.

  4. Good compatibility with PVC, chlorinated polyethylene (CPE), and other polar polymers without exudation or blooming.

  5. Non-volatile and non-staining—ideal for high-clarity and color-critical formulations such as medical tubing and food-contact films.

Typical Applications Of UPC UniHydro UN488 Dioctyl Terephthalate Plasticizer

  1. PVC wire & cable insulation and jacketing requiring UL/CSA compliance and extended service life.

  2. Automotive interior trim, seals, and under-hood components exposed to elevated temperatures and cyclic stress.

  3. Medical-grade flexible tubing and blood bags meeting ISO 10993 biocompatibility screening requirements.

  4. High-performance flooring, wall coverings, and synthetic leather with enhanced durability and weather resistance.

  5. Food packaging films and laminates where low extractables and regulatory acceptance are critical.
