Chemical Structure
Surfactant Type: Nonionic.

Markets: Industrial
Applications: Industrial — Chemical & Industrial Manufacturing
Chemical Manufacturing
Applicable Processes: Emulsion Polymerization,
Latex Manufacturing
Applications: POLYSTEP® F-9 surfactants are nonionic in nature; they neither ionize in water nor hydrolyze in aqueous acid or alkaline solutions. Chemically, they are the reaction products of nonylphenol and ethylene oxide. They differ in the mole ratio of hydrophilic ethylene oxide to hydrophobic nonylphenol. POLYSTEP® F-9 surfactants offer a broad range of properties. In combination with other surfactants POLYSTEP F products tend to increase latex particle size and contribute to freeze-thaw and mechanical stability.

Health Effects: These products are relatively harmless orally (LD₅₀ >16,000 mg/kg b.w.) and mildly to non-irritating to skin and eyes.

Packaging Type: Bulk,
Drums
Standard Packaging: : POLYSTEP F-9 is made-to-order materials available in drums and in bulk quantities.

Storage & Handling: Normal safety precautions (i.e., gloves and safety goggles) should be employed when handling POLYSTEP F products. Contact with the eyes and prolonged contact with the skin should be avoided. Wash thoroughly after handling material. It is recommended that POLYSTEP F products be stored in sealed containers and kept in a cool, dry place. If material has been frozen it should be heated gently and stirred to ensure it is homogeneous before use.

Bulk Storage Information

POLYSTEP F surfactants can be stored in vessels of 316 stainless steel. Material should be stored between 29 – 43 °C (85 – 110 °F). An internal hairpin coil of carbon steel with low pressure steam (under 50 psig) should be used if heating is required. Mild agitation is required if the tank is heated. Heating may not be required for inside storage if the tank is turned over frequently. Stainless steel 316 is preferred for pumps, pipes, and transfer lines.
Workplace Exposure: Occupational exposure can occur primarily through skin contact or via inhalation of vapors and mists Engineering controls, personal protective equipment, and other workplace practices should be used to control these exposures.
