Plurafac® LF 500 is a low-foaming nonionic surfactant that provides excellent foam control for Glucopon® surfactant and Deriphat® 160 C. It is mainly used for its wetting, low-foaming, or even defoaming properties. Plurafac® LF 500 finds applications in various industries, such as food and beverage processing, food service and kitchen hygiene, commercial laundry, institutional cleaning and sanitation, and industrial cleaning.

  • The solubility increases in line with their cloud point.
  • With a cloud point below room temperature can be made to form clear solutions by adding solubilizers such as alcohols, glycols or sodium cumene sulfonate. 
Viscosity Data

It is advisable to stir the surfactant into water when preparing aqueous solutions of Plurafac® LF types. The viscosity of solutions made up in the reverse order can be too high at certain concentrations. The relationship between the viscosity and water addition of solutions of Plurafac® LF types is shown in the tables below.

Note
     
  • * Method A: 7 g of surfactant + 100 g of distilled water
  •  
  • * Method B: 1 g of surfactant + 100 g of NaCl solution (c = 50 g/l)
  •  
  • * Method C: 1 g of surfactant + 100 g of NaCl solution (c = 100 g/l)
  •  
  • * Method D: 5 g of surfactant + 45 g of butyldiglycol solution (c = 250 g/l)
  •  
  • * Method E: 5 g of surfactant + 25 g of butyldiglycol solution (c = 250 g/l)

  • ** The Plurafac® LF types can undergo a decrease in PH during storage, but this does not affect their performance.

Storage & Handling

Storage Condition
  • The Plurafac® LF types should be stored indoors in their original packaging, which should be kept tightly sealed.
  • The Plurafac® LF types are hygroscopic and soluble in water, with the result that they absorb moisture very quickly. Drums should be tightly resealed each time material is taken from them.
  • The storage temperature should not be allowed to fall substantially below 20°C, and storerooms must not be overheated.
  • The Plurafac® LF types can become cloudy if they are stored at low temperatures, but this has no effect on their performance. The cloudiness can be dissipated by heating them to 40 - 50°C
  • Liquid that has solidified or that shows signs of precipitation should be heated to approx. 40 — 50°C before it is processed.
  • Drums that have solidified or that have begun to form a sediment should be reconstituted by gentle heating, preferably in a heating cabinet. The temperature must not be allowed to exceed 50 - 60°C. This also applies if drums are heated by external electrical elements. Internal electrical elements should not be used because of the localized anomalies in temperature that they cause.
  • The Plurafac® LF types must be blanketed with nitrogen if they are stored in heated tanks (at approx. 50°C) to prevent them from coming into contact with air. Gentle, constant stirring helps to prevent them being diskolored as a result of prolonged contact with electrical elements or external heating coils.
  • The following materials can be used for tanks and drums:
    • AISI 316 Ti stainless steel
    • AISI 321 stainless steel 
  • Provided they are stored properly and drums are kept tightly sealed, the Plurafac® LF types have a shelf life of at least two years in their original packaging.
