In the manufacturing of wires and cables, the insulation material is critical for ensuring electrical safety, performance, and longevity. Polyvinyl Chloride (PVC) is a widely used polymer for this purpose, and its properties are significantly enhanced by plasticizers. Dioctyl Terephthalate (DOTP) has emerged as a leading plasticizer for wire and cable insulation due to its exceptional balance of electrical properties, thermal stability, flexibility, and importantly, its eco-friendly profile. NINGBO INNO PHARMCHEM CO.,LTD. is a key provider of high-quality DOTP for this demanding sector.

Why DOTP is Superior for Wire and Cable Applications
Traditional plasticizers like DOP have limitations when it comes to high-performance electrical applications. DOTP offers distinct advantages that make it the preferred choice:

  • Excellent Electrical Insulation Properties: DOTP exhibits significantly higher volume resistivity compared to DOP. This characteristic is vital for electrical insulation, as it minimizes electrical leakage and ensures the integrity of the conductor. This makes cables safer and more efficient, especially under demanding voltage conditions.
  • Enhanced Thermal Stability: Wires and cables often operate at elevated temperatures, whether due to electrical current or ambient conditions. DOTP's superior thermal stability ensures that the PVC insulation maintains its integrity and flexibility even at higher temperatures, preventing degradation and failure.
  • Improved Flexibility and Cold Performance: The flexibility imparted by DOTP is crucial for ease of installation and durability. Furthermore, its excellent performance in cold temperatures ensures that cables remain pliable and resistant to cracking, even in frigid environments, which is essential for outdoor or industrial applications.
  • Low Volatility: Cables are often installed for long periods. DOTP's low volatility means the plasticizer remains within the PVC insulation for an extended lifespan, preserving the cable's flexibility and electrical properties over time. This reduces the risk of embrittlement and insulation breakdown.
  • Non-Phthalate and Eco-Friendly: With increasing regulatory focus on chemical safety, the non-phthalate nature of DOTP is a significant advantage. It ensures that the insulation materials are safe for workers during manufacturing and for end-users, aligning with global health and environmental standards. This is particularly important for cables used in sensitive environments or consumer products.

Applications in the Wire and Cable Industry
DOTP is an ideal plasticizer for a wide range of wire and cable applications, including:

  • Power Cables: Its high thermal stability and excellent electrical insulation properties make it perfect for power transmission and distribution cables operating under demanding conditions.
  • Building Wires: For internal wiring in residential and commercial buildings, DOTP ensures safety, flexibility, and long-term performance.
  • Automotive Wiring: The flexibility and temperature resistance of DOTP-plasticized PVC are crucial for the complex wiring harnesses found in vehicles.
  • Specialty Cables: For applications requiring specific electrical or environmental resistance, DOTP provides the necessary performance enhancements.
