Abstract
The present invention relates to a flame retardant hot melt composition comprising from about 20% to about 60% by weight of the adhesive of at least one copolymer of ethylene, from about 10% to about 50% by weight of the adhesive of a flame retarding hydrated inorganic compound, from about 10% to about 30% by weight of at least one high melting point wax and from about 1% to about 10% by weight of at least one tackifying resin.
Claims11
A High Efficiency Particulate Air Filter comprising:
- a) a material effective for filtering airborne contaminants;
