Abstract:
The present invention provides a polyvinyl chloride polymer (PVC) composite material including 40-60 parts by weight of PVC, 40-60 parts by weight of light calcium carbonate, 0.8-1.2 parts by weight of composite foaming agent including an inorganic foaming agent and an organic foaming agent, 3-5 parts by weight of foam regulator, 2-4 parts by weight of toughener, 0.8-1.2 parts by weight of lubricant, and 1.5-2.5 parts by weight of stabilizer. The ratio of the inorganic foaming agent to the organic foaming agent by weight in the composite foaming agent is ½-1. Meanwhile, the present invention provides a foam board made of the PVC composite material, an associated production method, an apparatus, and flooring. The resulting PVC products have a high-strength structure and a good foaming property, thus having a satisfied mute effect.

Abstract:
A urethane foam member that after cutting into the desired shape from sheet urethane foam is applied with adhesive on one face of the urethane foam, an edge portion of the non-adhesive applied face at least at one side of the urethane foam member being of a low edge profile, to which permanent thermal distortion has been induced such that the thickness of the edge portion of the side is thinnest at the end portion thereof and the thickness gradually increases with distance from the end portion.

Abstract:
A ceramic article having a ceramic substrate and a ceramic coating with an initial porosity and an initial amount of cracking is provided. The ceramic article is heated to a temperature range between about 1000° C. and about 1800° C. at a ramping rate of about 0.1° C. per minute to about 20° C. per minute. The ceramic article is heat treated at one or more temperatures within the temperature range for a duration of up to about 24 hours. The ceramic article is then cooled at the ramping rate, wherein after the heat treatment the ceramic coating has a reduced porosity and a reduced amount of cracking.

Abstract:
A process for producing an article in a flexible foamed polymer material, including treating a former with a coagulant; dipping the treated former in a latex foam mixture to form a layer of the mixture on the former that includes air cells; curing the layer to gel the foam mixture to a cross-linked open cell structure; and stripping the layer from the former; where the latex foam mixture includes a natural latex polymer as a primary polymer component, and a synthetic latex polymer as a secondary polymer component, which synthetic latex polymer is selected to enhance the evenness and/or fineness of said open cell structure.
Abstract:
Multilayer foam-film composite structures in which the cells of at least one foam layer have an anisotropic orientation exhibit at least one enhanced property of toughness, tear resistance and puncture resistance in comparison with a foam-film composite structure alike in all aspects except for the anisotropic orientation of the cells of at least one foam layer.
Abstract:
Building materials formed from synthetic polymer materials have an appearance which simulates natural woods. The building materials may be used in the construction of fences, sheds, decking materials, indoor/outdoor furniture, railings and numerous other products. The faux wood material is constructed to include reinforcing fibers and voids for weight reduction. The aesthetic appearance of the finished product can be enhanced by applying a color wash which includes a polymer component and a color component adhering to the surface of the material.
Abstract:
It comprises three layers: a first layer of plastic material that provides the whole with mechanical strength, a second intermediate layer of foam forming a union between the first and second layer, and a third layer of impermeable plastic material and is characterized in that the first layer (2) is mase on an elastomeric polyolefin of high strength and elasticity, in that the second layer (3) is of closed-cell, physically or chemically cross-linked polyethylene foam, and in that the third layer (4) is of polyolefin with high tear resistance. A light waterproofing sheet is obtained which withstands extreme meteorological conditions, is resistant to chemical agents, while it also has optimum mechanical properties at a lower thickness thanks to the material of which the first layer is comprised and unlike other sheets existing it has no ageing limit, which means that once the sheets have been fitted they do not have to be replaced.
