摘要:
The present invention pertains to carpet and carpet tile. In one aspect, the carpet includes (a) a primary backing which has a face and a back surface, (b) a plurality of fibers attached to the primary backing and extending from the face of the primary backing and exposed at the back surface of the primary backing, (c) an adhesive backing, (d) an optional secondary backing adjacent to the adhesive backing, and (e) at least one non-chlorinated, non-polyvinyl butyral thermoplastic polymer or composition having a specific growth tension at 40 C and a specific residual stress at 25% strain. Additional steps and procedures include washing or scouring the primary backing and fibers prior to the extrusion step, and utilizing implosion agents. The preferred olefin block copolymer are ethylene based block interpolymers. The constructions and methods described herein are particularly suited for making tufted, broad-loom carpet having improved abrasion resistance.
摘要:
The invention relates to an improved method of extracting a shaped foam article from a mold cavity after being formed, specifically by imparting a vacuum sufficient enough to hold the shaped foam article to one side of the mold, preferably the core half of the mold, when the mold opens.
摘要:
The present invention provides a dispersion, and a process for producing a dispersion. The dispersion according to the present invention comprises (a) one or more subparticles having an average particle size diameter in the range of 0.01 to 9 µm; (b) one or more base polymers at least partially encapsulating the one or more subparticles; wherein said at least partially encapsulated one or more subparticles have an average particle size diameter in the range of 0.05 to 10 µm; (c) one or more stabilizing agents; and (d) a liquid media comprising water.
摘要:
The present invention provides a multicomponent composition that is substantially isocyanate-free and comprises a polycarbamate as a first component and a polyaldehyde or an acetal or hemiacetal thereof as a second component and further comprises an effective amount of a triggering agent such that the first and second components to cure at a temperature of from 0C to less than 80C to form a crosslinked polyurethane. The multicomponent composition forms an ambient temperature curable composition when all of its components are combined that has a pH of 7.0 or less. The present invention also provides processes crosslinked polyurethanes, and the crosslinked polyurethanes prepared by the processes.

SiIyI terminated polyalkylene glycol lubricants for devices that provide cooling or refrigeration, refrigerant compositions including silyl terminated polyalkylene glycol lubricants, and methods for making the same. The lubricant is compatible with hydrofluorocarbon refrigerants such as hydrofluoroolefins ("HFO ⋆ ), R-134(a), R- 152(a), and carbon dioxide.
摘要:
The present invention is a method for degassing an electrical cable having a crosslinked, semiconductive shield layer prepared from a composition made from or containing (i) a phase I material consisting essentially of a polar copolymer of ethylene and an unsaturated ester having 4 to 20 carbon atoms, (ii) a phase II material consisting essentially of a nonpolar, low density polyethylene, and (iii) a conducting filler material dispersed in the phase I material and/or the phase II material. The degassing temperature is greater than 70 degrees Celsius.
