Product Overview: Propylene Glycol Block Polyether P84(CAS 9003-11-6)

Propylene glycol block polyether P84 (CAS 9003-11-6), also called PPG block polyether P84, is a non-ionic polyether surfactant. It features high stability, water solubility, and broad pH adaptability. As a versatile industrial additive, it acts as an emulsifier, dispersant, and anti-foaming agent, widely applied in pesticide formulations, metal processing fluids, detergents, coatings, and textile auxiliaries. Its low viscosity and strong compatibility make it ideal for multi-component product systems, while eco-friendly variants offer biodegradable performance.        

      

Product Advantage

  1. Stable Technical Performance
    It maintains consistency across pH 5.0–7.0, with low moisture (≤1.0%) and a controlled cloud point (72–76°C in 1% aqueous solution). This stability ensures reliable performance in diverse industrial formulations, reducing batch-to-batch variation. 
  2. Broad Compatibility
    As a non-ionic surfactant, it blends well with ionic/non-ionic additives, making it ideal for complex systems (e.g., detergent blends, pesticide formulations). Its low viscosity also simplifies mixing and processing in production lines. 
  3. Tailored Functional Traits
    With an HLB value of 14, it balances hydrophilic-lipophilic properties, enabling effective emulsification and defoaming. This versatility eliminates the need for multiple additives in a single formulation, cutting material costs.

Product Uses

  1. Detergent & Defoamer Applications
    It's formulated into low-foam, high-detergency synthetic detergents. In medical scenarios (e.g., artificial heart-lung machine circulation), it acts as a defoamer to prevent air entrainment, ensuring operational safety.
  2. Textile & Fiber Processing
    As a penetrant, it boosts dye absorption in fabric dyeing; when added (0.3% dosage) in wool finishing, it reduces fiber damage by 10% and lowers yarn breakage rate, enhancing product quality.
  3. Industrial Fluid Additive
    It serves as a dispersant in latex coatings and a lubricant in rubber vulcanization. In metal processing, it acts as a coolant/lubricant in cutting fluids, improving machining efficiency.


Product Operate Guide

For general applications (e.g., detergent blending), mix P84 directly with other components at 2–5% dosage (adjust based on formulation needs). For textile processing, dilute it to 0.2–0.5% concentration before adding to dye baths. Store in dry, ventilated areas (shelf life: 2 years) to maintain stability.


FAQ

  1. What's the shelf life of P84?
    It has a 2-year shelf life when stored in dry, ventilated environments (per chemical storage standards), with no performance degradation if sealed properly.
  2. Is P84 compatible with ionic additives?
    Yes, as a non-ionic polyether, it works well with both ionic and non-ionic ingredients, suitable for multi-component industrial formulations.
  3. What dosage is recommended for textile processing?
    A 0.3% dosage in wool finishing reduces fiber damage by 10% and lowers yarn breakage, while 0.2–0.5% (diluted) is ideal for fabric dyeing.
