Impact of flame retardants on smoke generating properties of acrylic pressure-sensitive adhesive transfer tapes

摘要

A com. polyacrylic pressure-sensitive adhesive was modified by addn. up to 35% by mass of 2 com. flame retardants (expanded graphite or a N-P-retardant) used for covering a polyester film substrate, cured with Al acetylacetonate and studied for smoke generation during flame or flame less combustion under IR irradn. of 25 KW/m(2) by detg. of sp. smoke d. The expanded graphite was an efficient smoke suppressant.
