Abstract
As an improved flame-resistant agent, pentabromodiphenyl ether and mixtures of pentabromodiphenyl ether and brominated diphenyl ethers; an agent for impregnating a mass of particles which comprises an impregnating agent, pentabromodiphenyl ether, preferably together with a plasticizer; a laminate substrate comprising a web of fibers impregnated with an impregnating agent and pentabromodiphenyl ether, said web preferably containing a plasticizer; a method of increasing the flame resistance of a continuous web impregnated with an impregnating agent which comprises including in said web pentabromodiphenyl ether.
Claims13
A flame-retardant laminated comprising a first layer, which first layer comprises between 35 and 65% by weight continuous layer of paper, the balance comprising a mixture of a synthetic resin of cresol or phenol, a plasticizer and pentabromodiphenyl ether alone or in a admixture with another brominated diphenyl ether, the amount of brominated diphenyl ether being between 5 and 15% based upon the weight of the moisture-free synthetic resin, the total percentage of brominated diphenyl ether amounting to between 5 and 15% by weight based upon the weight of moisture-free synthetic resin and plasticizer, and a second layer laminated to said first layer.
A laminate comprising at least one layer of paper, which paper is coated with a coating of synthetic resin, which coating contains pentabromodiphenyl ether, said synthetic resin being a condensation polymer of formaldehyde with cresol or phenol formed under alkaline conditions, said pentabromodiphenyl ether being present in an amount of between 0.5 and 15 weight percent based on the weight of said substrate, said paper having a second layer laminated thereto.
A laminate comprising at least one layer of a paper, which paper is coated with a coating of a synthetic resin, which coating contains pentabromodiphenyl ether, said synthetic resin being a condensation polymer of formaldehyde with cresol or phenol formed under alkaline conditions, said pentabromodiphenyl ether being present in an amount of between 0.5 and 15 weight percent based on the weight of said paper, said paper having laminated thereto a layer of a metal foil.
