Abstract:
Low adhesion backsize (LAB) compositions including a silicone macromonomer co polymerized with a crystalline (meth)acrylate monomer to form a copolymer. The copolymer exhibits a glass transition temperature of from about −15° C. to about 55° C., and a crystalline melt transition of from about 25° C. to about 80° C. Articles including the LAB composition applied to a first major surface of a substrate. In some exemplary embodiments, the article is an adhesive article. In certain exemplary embodiments, the article is a pressure-sensitive adhesive (PSA) article. In some particular embodiments, the PSA article includes a silicone adhesive applied to a second major surface of the substrate opposite the LAB composition. Methods of making and using the LAB and the articles are also disclosed.
Abstract:
Bi-directional and multi-axial fabrics, fabric composites, ballistically resistant assemblies thereof, and the methods by which they are made. The fabrics are comprised of sets of strong, substantially parallel, unidirectional yarns lying in parallel planes, one above the other, with the direction of the yarns in a given plane rotated at an angle to the direction of the yarns in adjacent planes; and one or more sets of yarns having lower strength and higher elongation interleaved with the strong yarns. The fabrics of the invention provide superior ballistic effectiveness compared to ordinary woven and knitted fabrics but retain the ease of manufacture on conventional looms and knitting machines.
Abstract:
An adhesive resin composition excellent in adhesiveness and heat resistance thereof, film-forming properties, and film quality and a laminate having an adhesive resin layer made of this adhesive resin composition are provided. The composition is an adhesive resin composition comprising 10-99.5% by weight resin ingredient (A), 0.5-30% by weight another resin ingredient (unsaturated-carboxylic-acid-modified polypropylene), and 0-89.5% by weight still another resin ingredient (olefin resin). Resin ingredient (A): a product of successive propylene polymerization comprising 10-60% by weight (propylene homopolymer) component and 40-90% by weight (propylene/ethylene copolymer) component. The contents of room-temperature-xylene solubles derived from (a2), room-temperature-xylene insolubles derived from (a2), and room-temperature-xylene solubles derived from the same are 1-20% by weight, lower than 20% by weight, and 10-60% by weight, respectively, based on resin ingredient (A). The room-temperature-xylene solubles derived from (a2) have a content of ±-olefins excluding propylene of 20% by weight or higher.
Abstract:
The invention relates to a multilayered material sheet comprising a consolidated stack of unidirectional monolayers of drawn polymer. The draw direction of two subsequent monolayers in the stack differs. Moreover the strength to thickness ratio of at least one monolayer is larger than 4.5.10 13 N/m 3 . The invention also relates to a ballistic resistant article comprising the multilayered material sheet and to a process for the preparation of the ballistic resistant article.
Abstract:
Breathable materials comprise a fabric layer and a polymer film layer thereon, the polymer film layer comprising a polymer composition and a filler, wherein the breathable material has undergone a physical manipulation to render the polymer film layer microporous such that the WVTR of the breathable material is greater than about 50 g/m2 24 hr, and wherein the breathable material has a first length dimension and a first width dimension before said physical manipulation and a second length dimension and a second width dimension after said physical manipulation, wherein the second length dimension is no more than about 2% greater than the first length dimension and the second width dimension is no more than about 2% greater than the first width dimension. Methods of making a breathable material comprise forming a polymer film layer comprising a polymer composition and a filler; bonding the polymer film layer to a fabric layer to form a laminate; and applying a physical manipulation to the laminate to render the polymer film layer microporous such that the WVTR of the resulting breathable material is greater than about 50 g/m2 24 hr; wherein the breathable material has a first length dimension and a first width dimension before said physical manipulation and a second length dimension and a second width dimension after said physical manipulation, wherein the second length dimension is no more than about 2% greater than the first length dimension and the second width dimension is no more than about 2% greater than the first width dimension.

Abstract:
Woven fabric laminates having superior resistance to penetration by ballistic projectiles, assemblies thereof, and the method by which they are made. In one embodiment, among others, a laminate of the invention is comprised of a fabric woven from a high strength, high modulus yarn, a surface coating of a low modulus elastomer and a plastic film bonded to its elastomer-coated surface.
Abstract:
A protective drainage wrap comprises a first portion, a second portion and a solid sheet portion. The first portion comprises cross-woven or cross-laminate material in the machine direction and in the transverse direction. The material in the machine direction comprises a polyolefin, polyester, nylon or combinations thereof and has a first thickness. The material in the transverse direction comprises a polyolefin, polyester, nylon or combinations thereof and has a second thickness. The second thickness is at least about 2 times greater than the first thickness so as to assist in providing drainage for moisture build-up. The second portion is a coating comprising a polyolefin, polyester, nylon or combinations thereof. The first and second portions are located adjacent to each other. The solid sheet portion comprises a polyolefin, polyester, nylon or combinations thereof. The solid sheet portion is attached to at least one of the first portion and the second portion.
