Plate-like particles of interest in this context include mica, aluminum flake, hammered glass, magnesium hydroxide and talc. Physical properties of composites containing these additives depend strongly on the flow-induced morphology and on the distribution of residual stresses [31]. [Pg.165]

Talc is a natural magnesium silicate, which when compounded with plastics improves, among other properties, the flame retardancy. For example, talc combined with magnesium hydroxide or ATH improved the fire-retardance behavior of PP and EVA.62-63... [Pg.203]

Talc particles of different lamellarity and specific surface area have been incorporated into polyethylene vinyl acetate (EVA) copolymer/magnesium hydroxide (MH) composite system.63 The fire retardancy of this system has been studied and compared with formulations containing only EVA and MH and formulations containing EVA, MH, and organomodified montmorillonites (oMMT). It was observed that talc with higher lamellar index showed fire behavior similar to that of EVA/MH/ oMMT system with some intumescence. [Pg.203]

Hydrated magnesium silicate (Talc, 3Mg0 4Si02 H20, CAS No. 14807-96-6) is a magnesium silicate commonly referred to as "soapstone". It is obtained from natural sources and may contain a small amount of aluminum silicate. It is composed of MgO (31.7%), Si02 (63.5%), and H2O (4.8%). It is a crystalline nonhygroscopic, odorless, tasteless powder which is practically insoluble in water, dilute mineral acids, dilute solutions of alkali halides, and alkaline hydroxides but is soluble in hot concentrated sulfuric acid.

Another trend in many applications is towards halogen-free products or at least to combinations which will permit a reduction in the percentage of halogen. Japanese patents have opened up the market for melamine compounds that can also be used in combination with other FRs such as magnesium hydroxide or even a filler like talc. [Pg.13]

Flame retardant performance can be enhanced in some magnesium hydroxide protected systems by the incorporation of clay or talc. In a polyethylene formulation the addition of 60% magnesium hydroxide and 5% tale instead of 65% magnesium hydroxide, improved the V-0 rating from 3.2 mm to the thinner 1.6 mm level. More tale at the expense of further magnesium hydroxide dropped the V-0 rating baek to 3.2 mm. [Pg.45]
