Leading Block Polyether (Poloxamer) Manufacturer | 7+ High-Performance Grades
ISO 9001 Certified Manufacturer of Block Polyethers. Custom EO/PO ratios available with full TDS & COA technical support for global supply.
Introduction to Block Polyether & Poloxamer
KEMAIX Block Polyether series, commonly known as Poloxamer or Pluronic, are non-ionic surfactants synthesized from ethylene oxide and propylene oxide. These versatile EO/PO Block Copolymers are characterized by their low toxicity and exceptional stability.
From pharmaceutical grade Poloxamer used as emulsifying agents to industrial-grade Block Polyether for papermaking, our products (L35, F68, L61, etc.) meet the most stringent application requirements.

Understanding Block Polyether Structure
The performance of Block Polyether (Poloxamer) is determined by the balance of Hydrophilic (Ethylene Oxide) and Hydrophobic (Propylene Oxide) segments.
Performance and Key Features of Block Polyether (Poloxamer)
The Block Polyether (Poloxamer) series is characterized by its versatile non-ionic nature, offering a unique combination of emulsification, lubrication, and low-foaming properties. Below is a detailed technical analysis of how our Poloxamer products serve various high-demand industries.
1. Advanced Detergency & Defoaming Control
Block Polyether L61, L64, and F68 are premier choices for formulating synthetic detergents that require low foam profile and high detergency. Specifically, Poloxamer L61 is widely utilized as a high-efficiency defoamer in the papermaking and microbial fermentation industries.
2. Pharmaceutical Excipients & Cosmetics Grade Poloxamer
Due to their exceptionally low toxicity, Block Polyethers are essential pharmaceutical excipients. They are trusted emulsifying agents in oral preparations, nasal sprays, eye/ear drops, and high-end shampoos.
Poloxamer F38 stands out as a multi-functional base for agrochemicals, cosmetics, and pharmaceuticals, serving as a viscosity modifier, gelling agent, and rinsing aid.
3. Industrial Lubrication & Textile Auxiliaries
In metalworking, these polyethers serve as high-performance coolants and lubricants for cutting and grinding.
For the textile industry, Poloxamer L44 provides durable antistatic protection for synthetic fibers. In the wool industry, P65 acts as a critical wool protective agent; adding 0.3% during carbonization reduces scale damage, increases single-fiber strength by 10%, and significantly reduces yarn breakage during spinning.
4. Dispersants and Emulsifiers for Coatings & Agrochemicals
Block Polyether F68 is a powerful emulsifier in vinyl acetate emulsion polymerization and a wetting agent in sugar mills to enhance water penetration. Grades like L62 and L64 are standard emulsifiers for agrochemicals (pesticides).
In papermaking, F68 effectively improves the surface quality and gloss of coated art paper, while also serving as an effective wetting agent in textile dyeing and electroplating acid baths.
5. Crude Oil Demulsification & Oilfield Chemicals
Our Block Polyether series (L64, F68) serves as effective crude-oil demulsifiers. They play a vital role in secondary oil recovery and effectively prevent hard scale deposition in oil pipelines, ensuring smooth transport and enhanced extraction efficiency.
Packaging, Storage & Transportation
Standard Packaging
- Liquid/Paste Grades: 200 kg steel drums or 50 kg plastic drums.
- Solid/Flake Grades (F68/F38): 25 kg paper bags or fiber drums with internal plastic liners.
Storage & Handling
Products should be stored in a cool, dry, and well-ventilated warehouse. Keep containers tightly closed when not in use. As Block Polyethers are non-toxic and non-flammable, they can be transported as general chemicals.
Shelf Life: 2 Years from the date of manufacture.
