Title: Elvin M Weidman: Innovator in Resin Technology
Introduction
Elvin M Weidman is a notable inventor based in Willow Street, PA (US). He has made significant contributions to the field of resin technology, holding a total of 3 patents. His innovative work has led to advancements in materials that are widely used in various industries.
Latest Patents
Weidman's latest patents include a highly filled resin powder and a vinyl structure with an embossed top layer and foam base. The highly filled PVC resin powder is created by coating filler particles with a liquid and blending them with a dispersion grade PVC resin. This process allows for the formation of resin compositions containing 60% to 95% filler, with a majority of the resin particles measuring less than 15 microns. The filler particles are designed to have a specific size distribution, ensuring that at least 50% by weight are retained on a 200 mesh screen. The liquid used in this composition acts as a plasticizer and/or stabilizer, enabling the creation of a porous mass or layer that can be printed with plastisol or acrylate ink.
The vinyl structure patent describes a unique technique that results in an embossed top layer made from a material that fuses and is embossable at a lower temperature than the foam base. This innovative method allows for the top layer to be softened and embossed without affecting the underlying foam base, creating a distinct product with both aesthetic and functional properties.
