ABSTRACT:
Polymeric materials are combined with modified heat exfoliated hydrated magnesium aluminosilicates. The aluminosilicates are treated with aqueous acidic solutions and subjected to controlled agitation to convert highly porous concertina-shaped granular hydrated magnesium aluminosilicates into groups of electrolyte insensitive platelets. Water slurries of the groups of platelets when dried form coherent, continuous sheets which when mechanically disintegrated may be reslurried in water. The modified heat exfoliated magnesium aluminosilicates are adapted for use in fire retardant, loose fill cellulose insulation, paper and pulp products, synthetic polymeric materials, coatings such as fire retardant acoustic coatings, dog foods, defoliants and the like.
