  1. Plastic Industry: DNOP is primarily used as a plasticizer in the production of flexible polyvinyl chloride (PVC) products. It improves the flexibility, durability, and workability of PVC materials, making them suitable for applications such as cables, hoses, flooring, and vinyl upholstery.
  2. Adhesives and Sealants: DNOP is used as a plasticizer in adhesives and sealants to enhance their flexibility and adhesive properties.
  3. Coatings and Paints: It can be added to coatings and paints to improve their film-forming properties, adhesion, and flexibility.
  4. Personal Care Products: DNOP is used in some personal care products, including cosmetics, as an ingredient to enhance their texture and improve spreadability.

Key Features:

  1. Excellent Plasticizing Properties: DNOP exhibits excellent plasticizing properties, allowing it to effectively soften and increase the flexibility of PVC and other polymers.
  2. Low Volatility: It has low volatility, which contributes to the stability and durability of products over time.
  3. Good Heat Stability: DNOP offers good heat stability, ensuring that the plasticized materials maintain their properties even under high-temperature conditions.
  4. Compatibility: It is compatible with various polymers, making it versatile and suitable for a wide range of applications.
  5. Regulatory Compliance: Our DNOP products meet relevant industry standards and regulations, ensuring their safety and compliance with regulatory requirements.
