Polyoxyethylene - Polyoxypropylene Block Copolymer, (Pluronic type nonionic surfactant)"NEWPOL PE"
What's great about Sanyo Chemical's polyoxyethylene-polyoxypropylene block copolymer "NEWPOL PE"
1
Pluronic type nonionic surfactant
The main component of "NEWPOL PE" is a block copolymer of ethylene oxide (EO) and propylene oxide (PO), a pluronic type nonionic surfactant with a polyoxypropylene chain as a hydrophobic group in the center of the molecular chain and polyoxyethylene chains as hydrophilic groups on both ends.
2
Lineup of products with distinctive features and a wide variety of functions can be added
Depending on the molecular weight of the polyoxypropylene and polyoxyethylene chains, the products are characterized by their appearance (liquid, solid, etc.), foaming and defoaming properties, cleaning power, emulsifying and dispersing power, and dissolving speed in water.
3
A raw material for many chemical products
"NEWPOL PE" products has primary OH groups at both ends of the molecule, so it is also used as a raw material for polyurethane resins and polyester resins.
"NEWPOL PE" products are pluronic type non-ionic surfactants (polyoxyethylene polyoxypropylene block polymer) that are used in a variety of fields.
Structrural formula of "NEWPOL PE" products
Pluronic type nonionic surfactant (polyoxyethylene polyoxypropylene block copolymer)
Main applications of "NEWPOL PE" products
"NEWPOL PE" products is used in a variety of applications due to the following features.
As a nonionic surfactant, it exhibits surfactant performance even in the presence of acids, alkalis, and metallic salts, and because it is polyether-based, it does not hydrolyze.
It has relatively low foaming and good foam breaking properties among nonionic surfactants.
Dissolves in water at any ratio as long as the temperature is below the cloud point.

Textiles
"NEWPOL PE" products can be used as raw materials for scouring agents, compound fiber oils, antistatic agents, and glue removers.
3
Cleaning agent for machinery and metal parts
"NEWPOL PE" products can be used as raw materials for acid cleaning agents, alkali cleaning agents, electrolytic cleaning agents, and spray cleaning agents. Examples of formulations for corrosion resistance to steel plates in hydrochloric acid and sulfuric acid baths and alkaline soaking detergents are shown below.
NEWPOL PE-34, PE-61, PE-62, PE-64, PE-71, PE-74, and PE-75 have low foaming properties and are suitable as metal cleaning agents.
They are practically non-corrosive to metals, and when used for acid cleaning, they exhibit anti-corrosion properties for steel plates.
