29、lubility It is a general rule that the solubility of PluronicPE types in water increases in step with the proportion of polyethylene glycol that they contain. If two products contain the same mass fraction of polyethylene glycol, the molar mass of the polypropylene glycol block is the determining fa

30、ctor, and the one with the lower molar mass will be the more soluble.For instance, PluronicPE 6800 is more soluble in water than PluronicPE 6100, which is less soluble than PluronicPE 3100. All of the PluronicPE types are more soluble in cold water than in hot water. As in all alkoxylates, the oxyge

31、n atoms in the ether groups form hydro-gen bonds with water. The molecules gradually dissociate as the solution warms up. It is for this reason that alkoxylates have a cloud point at which they form a separate phase. Each product in the PluronicPE range has its own characteristic cloud point.TI/ES 1

35、March 2005 Page 7 of 16 PluronicPE typesWetting The most effective wetting agents contain a low proportion of polyethylene glycol, and their central polypropylene glycol block has a high molar mass. The best wetting agents in the range are PluronicPE 8100, PE 9200 and PE 10100. Compatibility The Plu

36、ronicPE types are nonionic and therefore miscible with anionic, cat-ionic and other nonionic surfactants. They do not react with cations such as Ca2+or Mg2+, which means that they can be used in hard water. They are also compatible with soluble polyanionic substances such as our SokalanCP types, Sok

37、alanPA types and carboxymethyl cellulose.The PluronicPE types are fully resistant to non-oxidizing acids at the con-centrations at which they are normally employed in applications such as those described below but, although they are resistant to alkalis, they are not resistant to alkalis to quite th

38、e same extent.Processing It is advisable to stir the surfactant into water when preparing aqueous solu-tions, because solutions made up in the reverse order can have a very high viscosity. Products with a high molar mass also form gels in water at certain concentrations. The relationship between vis

39、cosity and concentration is shown in the table below.The viscosities of aqueous solutions of PluronicPE types in mPa s (approx.)(The values below were measured at 25 C with a Brookfield viscometer)PluronicPE 3100 PE 3500 PE 4300 PE 6100 PE 6120Water content (%)0 175 440 400 350 41010 170 450 600 380

Storerooms must not be over-heated.b) The PluronicPE type

44、s 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.c) The PluronicPE types should not be stored at temperatures substan-tially below 20 C.d) The PluronicPE types can become cloudy liqu

45、ids at low temperatures and/or after long periods in storage, and this can cause them to form a sediment. This cloudiness is reversible at 50 60 C. Reconstitution has no effect on their practical performance.e) Liquid that has solidified or that shows signs of precipitation should be heated to 50 60

46、C and homogenized before use.TI/ES 1026 e March 2005 Page 10 of 16 PluronicPE typesf) Drums that have solidified or that have begun to precipitate should be reconstituted by gentle heating, preferably in a heating cabinet. The tem-perature must not be allowed to exceed 50 C. This also applies if dru

47、ms are heated by external electrical elements. Internal electrical elements should not be used because of the localized anomalies in temperature that they cause.g) The PluronicPE types must be blanketed with nitrogen if they are stored in heated tanks (at approx. 50 C) to prevent them from com-ing i

48、nto contact with air. Constant, gentle stirring helps to prevent them being discoloured as a result of prolonged contact with electrical elements or external heating coils.h) PluronicPE 6800 should be stored in a dry place at a temperature not exceeding 25 30 C. It must be protected from sunlight to ensure that it does not form lumps.Materials The PluronicPE types should be stored in tanks made from the following materials.a) AISI 316 Ti stainless steelb) AISI 321 stainless steelShelf life The PluronicPE types have a shelf life of at least two years, provided they are stored in th
