Latest Patents
One of Maeda's latest patents is for pre-expanded particles of non-crosslinked linear low density polyethylene. This invention features a pre-expanded particle with an average cell diameter ranging from 120 to 1,200 micrometers. It can be molded without the need for further expandability prior to molding or aging under pressure. The process involves heating in a closed mold that is permeable to a fluid heating medium, such as steam, resulting in a well-bonded unitary cellular molded article. This article boasts a good appearance, a high expansion ratio, and improved heat resistance and mechanical properties, with only slight volumetric shrinkage.
Another notable patent is the process for the production of expansion-molded articles in a mold of linear low density polyethylene resin. This process involves compressing pre-expanded linear low density polyethylene resin beads that exhibit two melting points when measured by differential scanning calorimetry. The invention provides a method to produce high-quality molded articles with specific thermal properties.
