摘要： An EPDM flashing composition comprises 100 parts by weight of an elastomeric polymer comprising from about 85 to 100 parts by weight of at least one ethylene-propylene-diene terpolymer having up to about 2 percent by weight crystallinity and from 0 to about 15 parts by weight of an ethylene-propylene-diene terpolymer having more than 2 percent by weight crystallinity; from about 40 to 120 parts by weight of a filler selected from the group consisting of reinforcing and non-reinforcing materials and mixtures thereof, per 100 parts of the polymer; from about 40 to 105 parts by weight of a processing material and mixtures thereof, per 100 parts of the polymer; and from about 0.5 to 6 parts by weight of a cure package, per 100 parts of the polymer, the cure package comprising from about 0.1 to 1.25 parts by weight sulfur and from 0.4 to 5 parts by weight of at least one sulfur vulcanizing accelerator and being devoid of hexasulfides and thioureas. The uncured EPDM flashing composition has a longer shelf-life than current uncured, calendered commercial EPDM flashing materials, and meets the flexibility, extensibility and green strength requirements and cure characteristics desired of comer flashing compositions. Preferably, the composition has a Mooney viscosity (ML/1+4 at 135 .degree. C.) of less than about 35 Mooney units and a green strength at break of less than 65 psi.

摘要： An adhesive tape composition includes a polymer blend comprising at least one EPDM rubber, and preferably three EPDM rubbers in substantially equal amounts, and an adhesive-enhancing polymer selected from the group consisting of polyisoprene, polybutadiene, and ethylene-propylene copolymer and mixtures thereof. The tape adhesive composition further includes at least one tackifying additive compatible with said polymer blend and a sulfur and organic accelerator cure, package for said polymer blend, the adhesive composition being devoid of butyl rubber which is found in most other adhesive tape compositions. This composition is seen as providing excellent long-term heat aging, weathering resistance, and low temperature properties as compared to adhesive tape compositions containing butyl rubber. Moreover, the adhesive tape composition provides more surface tack, better "quick-grab", and higher green strength as compared to adhesive tape compositions containing 100 percent EPDM rubber. A method is also provided for covering roofs which includes the step of employing the adhesive tape composition.

摘要： An ostomy appliance in which a pair of semi-rigid coupling rings and a flexible, resilient web are utilized for detachably connecting a collection pouch to a flexible faceplate. The appliance consists of two main parts: a pouch on which one of the coupling rings is mounted, and a faceplate to which the other of the rings is connected by means of the flexible annular web. The web allows limited floating action between the second coupling ring and the faceplate.

摘要： Flat rubber sheets are joined together at their primed surfaces utilizing an adhesive tape composition which features at least one EPDM rubber and will provide a long-term, water-tight barrier. The adhesive tape composition is a solventless, preformed, tacky composition comprising a) at least one crosslinkable EPDM rubber, b) a filler, either of the reinforcing or semi-reinforcing variety, c) one or more compatible tackifiers, d) a softener, and lastly, e) a cure system for the rubbery polymer.

摘要： A laminate cover for sealing an opening in a weatherproof roofing membrane includes a top sheet of a weather resistant material, preferably an uncured butyl rubber EPDM material, and a complementary shaped and sized lower sheet of a lightly cured butyl rubber having opposed tacky surfaces. A layer of a flowable sealing material such as an uncured butyl rubber sealing compound having a smaller dimension than that of the lower sheet, is trapped between the lower sheet and a bottom release coated carrier. Upon removal of the carrier, the cover is pressed over the opening to be sealed and an exposed peripheral tacky area of the lower sheet secures the cover to the membrane and traps the sealing compound therein. Applied or ambient heat will cause the sealing compound to flow into the opening to effectively seal the same, and will vulcanize the top sheet to provide abrasion and weather resistance for the cover.

摘要： A male urinary drainage device composed of a thin resilient external catheter or sheath and an adhesive sealant pad for holding the sheath in place and for producing an effective seal to prevent urine backup and leakage. The pad is formed of compressible, deformable, water-resistant, and elastic sealant material and includes a ring portion adapted to seal about the penis at or directly behind the glans thereof and at least one integral strap portion projecting radially from the ring portion and intended to extend along the penile shaft. The strap portion functions primarily to provide sheath retention, whereas the ring portion coacts with the retained sheath and with the penis to serve primarily as a barrier against fluid backup.

摘要： Vulcanizable elastomeric roof sheet materials for roofing having improved burn resistivity and prepared from a polymeric composition of matter comprise at least one polymer selected from the group consisting of polyolefins prepared from monomers containing at least two carbon atoms and mixtures thereof, the polymer having a crystallinity of up to about 2 percent by weight; about 20 to 125 parts by weight of one or more non-black mineral fillers per 100 parts of the polymer, about 50 to 110 parts by weight of one or more black-type fillers per 100 parts of the polymer; and from about 50 to 70 parts by weight of a processing material or softener per 100 parts of the polymer. A method of covering a roof comprises the steps of applying sheets of vulcanizable elastomeric roof sheet material prepared from a vulcanizable polymeric composition of matter, to the roof being covered; overlapping adjacent edges of the roof sheet material; and adhesively seaming the overlapped layers of the roof sheet material together to form a continuous elastomeric roofing membrane. The composition of matter is devoid of any flame retardant rubber chemical additives, heavy metals and halogen-containing polymers and possess improved burn resistivity.
