DOTP Optimizes Stability and Flexibility for an Uzbekistan Soft PVC Compound Producer

Henan GO Biotech Co., Ltd. supported an Uzbekistan PVC compound producer in optimizing its plasticizer system with DOTP, helping create a more stable material foundation for flexible PVC applications including cable, film, artificial leather and other soft products.

Project Background and Challenges

The customer produces general-purpose soft PVC compounds for multiple downstream industries. As requirements for material consistency, environmental attributes and long-term performance increased, the existing plasticizer system needed to better support continuous production and diverse application needs.

  • Batch consistency: Stable hardness, appearance, plasticization and processing flow were important for reliable supply to different processors.
  • PVC compatibility: The formulation required good compatibility to support uniform plasticization and reduce risks associated with surface instability, migration or exudation.
  • Flexible performance: The compound needed to maintain reliable softness while remaining suitable for varied downstream processing conditions.
  • Long-term stability: Better heat resistance, low volatility and aging performance were needed for applications such as cable, film and flexible PVC products.

Solution: DOTP-Based PVC Formulation Optimization

Based on the customer’s soft PVC compound production scenario, Henan GO Biotech Co., Ltd. recommended DOTP as the primary plasticizer. DOTP is a non-phthalate plasticizer with good PVC compatibility, plasticizing efficiency close to DOP, low volatility, low migration and favorable heat-resistance characteristics.

  1. 1. Application Analysis Review soft PVC compound requirements across cable, film and flexible product applications.
  2. 2. Product Recommendation Select DOTP as a practical DOP replacement or optimization option for the PVC system.
  3. 3. Formulation Optimization Support a balanced approach to softness, process stability and surface performance.
  4. 4. Performance Validation Evaluate processing continuity, flexibility and long-term application suitability.

Project Results and Phase Value

By adopting DOTP as the primary plasticizer, the customer strengthened the consistency of its PVC compound production, improved flexibility and processing adaptability, and established a clearer non-phthalate plasticizer pathway. The optimized material basis supports more stable supply to downstream customers while improving suitability for flexible PVC applications requiring dependable surface, aging and processing performance.
