Latest Patents
Ohta's latest patents include innovative designs for polypropylene-based resin expanded beads. One of his notable inventions is a polypropylene-based resin expanded bead that features a tubular shape with a through-hole. This expanded bead contains a foamed core layer made from a polypropylene-based resin, which is covered by a fusion-bonding layer. The design specifies that the average hole diameter of the through-hole is less than 1 mm, and the mass ratio of the foamed core layer to the fusion-bondable layer ranges from 99.5:0.5 to 85:15. The polypropylene-based resin used in the foamed core layer has a flexural modulus of 800 MPa or more and a melting point of 150° C. or lower.
Another patent focuses on an expanded bead with a tubular shape and a method for producing it. This expanded bead also includes a foamed core layer and a covering layer, where the polyolefin-based resin in the covering layer has a melting point lower than that of the polypropylene-based resin in the foamed core layer. The specifications for the average hole diameter and the ratio of the hole diameter to the outer diameter are similar to his previous patent, showcasing Ohta's commitment to precision and innovation.
