摘要:
A product, generally in sheet form, allowing adjustment in positioning on installation and subsequent removal, the product comprises: a layer comprising crumb-rubber material, and having a first side and a second side. Scrim material is bonded to at least one of the first and second sides. A coating of a low-grab pressure sensitive adhesive is applied to at least part of the exposed surface of the scrim material. The adhesive is determined to be a low-grab adhesive if, after 24 hours adhesive binding dwell-time, a 90° peel adhesion at 300 mm/minute, as measured by the FINAT Test Method No: 2, of between 1.77 and 3.96 Newtons/25 mm width at room temperature (23° C.±1° C.) and at a relative humidity of 50%±5%.
摘要:
A process and system for making a laminated surface covering and the surface covering itself are described. The covering includes several layers bonded to each other. The system performs the process. One example of the process includes passing a first material across a first conveyor, passing a second material across a second conveyor, passing a bonding material across a third conveyor, contacting the first material and the second material to the bonding material, and heating at least one of the first material and the second material. The process also includes introducing the first material, the second material, and the bonding material into a pressure zone such that the bonding material is introduced between a bottom surface of the first material and a top surface of the second material. The process applies pressure to bond the first material and second material together via the bonding material to produce a laminated material.
摘要:
The present invention relates to a composite article obtained from binding or adhesion of particulate matter with a polyurethane binder which is derived from a urethane-modified isocyanate obtained by reaction of an isocyanate with a polyether polyol based on an initiator containing a tertiary nitrogen atom. Such composite articles can be, for example, recreational matting or tiles, sports or running tracks, or flooring, or laminates.
摘要:
An embossed release paper for production of synthetic leather that has shaping capability, thermal stability and durability, excelling in peeling capability as to two-component curing type PU adhesives, and that is applicable to any of synthetic leathers of PU and PVC and semisynthetic leathers; and a process for producing the same. There is provided an embossed release paper for production of synthetic leather, comprising at least a paper as a support and, superimposed thereon, an ionizing radiation-cured film, the cured film having been subjected to emboss finishing, wherein the ionizing radiation-cured film is one resulting from curing of a coating liquid of specified composition by exposing the same to ionizing radiation.
摘要:
A laminate film having a polyetheramine resin-containing layer on a first polyolefin resin-containing layer or a first polyethylene terephthalate resin-containing layer, wherein the polyetheramine resin contains of at least 30% resorcinol diglycidyl ether comonomer content is disclosed. The laminate film could further have additional layers such as a second polyolefin resin-containing layer, a second polyethylene terephthalate resin-containing layer, a metal layer or combinations thereof.
摘要:
A laminate film including a first polyolefin layer comprising of a blend of 50-95% ethylene-propylene copolymer and 50-5% ethylene polar terpolymer with a polar polymer layer on one side of said first polyolefin resin-containing layer is disclosed. The laminate film could further have additional layers such as a second polyolefin resin-containing layer, a metal layer, or combinations thereof.
