KEY CHEMICALS FROM WYANDOTTE
What's so versatile about Pluronic polyols? P | O i l t i l l Within the Pluronic® series are grades that I I v l l l j f • can be used as emulsifiers and demulsifiers; as foaming agents and defoamers. Some grades specialize as binders in tableting, as emulsion stabilizers and as dispersing and wetting agents. Still others react with isocyanates to make urethane foam, sealants and coatings. There are more than 30 chemically related Pluronic grades commercially available. Physical forms range from mobile liquids, pastes and powder to cast solid forms. And Pluronic polyols are used by a galaxy of industries including cosmetics, pharmaceuticals, petroleum, textiles, and paints, in addition to paper, dyes and insecticides. In fact, by most industries whose products or processing require surface-active properties. And Pluronic polyols have a low order of toxicity. Their
INDUSTRIAL CHEMICALS GROUP WYANDOTTE CHEMICALS CORPORATION DEPARTMENT 540 WYANDOTTE, MICHIGAN 48192
grade structure covers a molecular weight range from 1,000 to over 16,000: The higher the molecular weight, the lower the toxicity. Important considerations for food processors, cosmetic formulators and food packaging manufacturers. Very few chemical families offer the versatility of this unique series of 100% active, nonionic surfactants. Whatever you make, if you have need for an experienced surfactant, take full advantage of the versatility and other desirable characteristics of the Pluronic polyol series.
