TITLE: COMPOSITION P'OR MOLDED ~'r~ S'fO>?
FTELD OF THE INVENTION
The present invention relates to a composition which can be molded into a coupling for PVC and other plastic pipe to function as a Pire stop for preventing the spread of fire through openings or penetrations in the walls and floors of buildings.
HACKCROUND OF THE INVENTION
Fire stop devices are used to prevent fire from spreading from one room to another through openings or apertures in a partition such as a wall, floor or ceiling through which a pipe passes. The purpose of the fire stop device is to close off the opening in the partition in the event of a fire. The fire stop device generally c4ra,tains ari intumescent material which expands when the temperature reaches a certain level. The expansion of the intumesCAnt ItLatBri81 is directed inwardly toward the pipe and crushes the pipe which is generally softened by the Gemperatuxes encountered in a fire and closes off the opening in the wall with a hard char.
A numbdr of such fire stop devices have been proposed requiring field installation whereby for example foil lined strips Qf intumoscen,t material are wrapped around a plate and then a restraining collar is wrapped around the intumescent material and secured riy screws or straps.
Examples of many such fire stops are provided in amongst others U.S. pat~nt 5,498 466, 5,953,872, 5,634,304, 5,390,465, and 5,076,309. The installation of such fire stop devices can be labor-intensive and requires that .. 1 _ JUN-22-2001 16:59 DENNISON i MACBETH 416 368 1645 P.04i08 ~J-11 a~scA

S[~ARY OF THE INVEN'I:'I4N
The present ir~vention is directed to a composition which can be molded into a coupling for PVG and other plastic pipe to function as a fire stop. ~rhe composition comprises 100 parts by weight of a PVC resin and 20 to 100 parts by weight of an intumescent material, preferably exfoliated graphite.

A particularly preferred composition for infection molding contains 100 parts by weight of PVC resins, 2.5 parts by weight of one or more stabilizers, 4.9 parts bx weight of one or more lubricants, 8.0 parts by weight of an acrylic modifier, 3.0 parts by weight of acrylic processing aid, 25 parts by weight of exfoliated graphitA end 1.2 parts by weight of a foaming agent.
other preferred embodiments of compositions according to present inventipn contain 100 parts by weight of PVC
resins 2 to 3 parts by weight of one or more stabilisers, 25 to 1D0 parts by weight Qf exfoliated graphite, up to 1.2 parts by weight of foaming agent and up to 100 parts by weight of one or more plasticizers- Particularly preferred embodimerxts of these compositions contain 100 parts by weight of PVC xesin, 2 parts by weight of one or more stabilizer, 25 to 85 parts by weight of exfoliated graphite 0.6 to 1.2 parts by weight of foaming agent and 87 parts by weight of plastici~er.
the compositions according the present invention are prepared in a conventional manner by mixing the components of the compositions together and then molded in a suitable opex'ation to form the fixe stop couplings of the present invCntion. The fire Stop Couplings are utilized to bridge apenings ~-n partitions such that when the coupling is exposed to the high heat of a fire, the intumescent material such as the exfoliated graphite expands to close off the opening in the partition to prevent the spread of fire through the opening.

Rather, the ~ire stop coupling is used to join two pieties o~ PVC pipe to~ethar through the opening. This makes the installation of the piping systems much easier and reduces costs associated with pip9 iristallatl.ons.
