Product Description

Propylene Glycol Block Polyether L43(CAS 9003-11-6): Overview

Propylene Glycol Block Polyether L43 (CAS 9003-11-6) is a versatile polyoxypropylene-polyoxyethylene block copolymer (also called PPG block polyether L43 or PEO-PPO block polyether L43). As a high-performance nonionic surfactant, it functions as an emulsifier, dispersant, and wetting agent, widely applied in pesticides, coatings, inks, and chemical formulations.

Featuring low foam, good water solubility, and high stability, it enhances product uniformity and processing efficiency. Available in industrial grade, it suits batch production with customizable packaging, meeting diverse industrial application needs.

Product Advantage

Stable Technical Parameters
With a fixed 35–45% active content and 40–50°C cloud point, L43 maintains consistent performance in diverse temperatures, ensuring formulation stability (e.g., in pesticide emulsions). Its ≤1.0% moisture content reduces risk of system dilution.
Balanced HLB for Versatility
Boasting an HLB value of 10, it balances lipophilic-hydrophilic properties, making it effective as both an emulsifier (for oil-water systems) and wetting agent (for surface spreading)—suitable for multi-scenario industrial use.
Broad pH Compatibility
Its 5.0–7.0 pH (1% solution) allows seamless integration into neutral/slightly acidic/basic formulations (e.g., coatings, inks), eliminating the need for pH adjustment and simplifying production processes.
Low-Impact Physical Form
As a transparent liquid, L43 blends easily with other materials, cutting mixing time by ~10% compared to solid alternatives. Its pale yellow hue avoids discoloring light-toned end products.

Product Uses

Pesticide Formulations
Serves as an emulsifier in pesticide emulsifiable concentrates, enhancing active ingredient dispersion and crop surface adhesion—improving pest control efficiency while reducing product waste.
Coatings & Inks
Acts as a dispersant to prevent pigment sedimentation in coatings/inks, ensuring uniform texture and finish. Its wetting property also boosts substrate adhesion for longer-lasting products.
Textile Processing
Functions as a lubricant in textile manufacturing, reducing fiber friction during spinning/weaving. It also aids in dye dispersion, promoting even coloration of fabrics.

Product Operate Guide

To use L43:

1) Dilute to 1–5% concentration with water/base material;

2) Add to the formulation during mixing (stir at 500–800 rpm for 10–15 mins);

3) Use 2–8% of total formulation weight (adjust per application). Avoid mixing above 60°C to preserve cloud point stability.

FAQ

What's L43's shelf life?It has a 2-year shelf life when stored in cool, ventilated areas (avoid direct sunlight/moisture). Unsealed containers should be used within 3 months.
Can L43 mix with other surfactants?Yes, it's compatible with most nonionic/anionic surfactants. Test small batches first to optimize ratios for specific formulations (e.g., pesticide blends).
Is L43 suitable for food applications?No, L43 is industrial-grade, designed for sectors like pesticides, coatings, and textiles—do not use in food, pharmaceutical, or cosmetic products.
