Abstract:
A hot-melt adhesive composition based on ethylene/vinyl acetate copolymer, which copolymer has (a) at least 16% by weight vinyl acetate content and (b) a Melt Flow Index of at least 100 g/10 minutes at 190.degree. C. using a 2.16 kg. weight according to ASTM D138 (1979), the adhesive composition comprising not more than 35% by weight, based on the whole composition, of halogen-free char-forming flame-retardant additive(s) in an amount at least sufficient to prevent flaming drips generated on burning of the adhesive from igniting the underlying absorbent cotton according to the 20 mm Vertical Burn Test of Underwriters Laboratories Test Method UL-94 (1993), V-1, while leaving the adhesive composition with a Melt Flow Index (tested as above) of at least 50 g/10 minutes, and wherein the flame-retardant additive is phosphorous-containing and comprises one of (a) ammonium phosphate, and (b) an organic amine phosphate.
