A soundproof material includes rubber sponge having a specific gravity of 0.2 or less, which is formed by extrusion molding and a subsequent crosslinking and foaming of a rubber composition using a microwave heating device. The rubber composition includes at least raw material rubber, a crosslinking agent, a foaming agent, and carbon black. The soundproof material has a rectangular cross-sectional outer shape, has at least two hollow parts inside formed by a lateral partition wall extending in a left-right lateral direction and at least two hollow parts formed by a vertical partition wall extending in a vertical direction. The method includes adding carbon nanotubes to the rubber composition.

A method of making molded foam articles and the articles produced. A molded foam article is produced by heating or preheating the mold to a temperature at or above the glass transition or melt temperature of the particles to be molded. Foamed particles are then introduced into the mold. The particle filled mold is then subjected to a vacuum to stabilize the molded article, without application of any additional heating or cooling. The molded article is then removed from the mold at a temperature at or below the glass transition temperature of the particles, and the cycle repeated to form multiple molded articles.

A method for producing a foam-molded product by using a plasticizing cylinder, includes: plasticizing and melting the thermoplastic resin to provide the molten resin in a plasticization zone of the plasticizing cylinder; introducing a pressurized fluid containing the physical foaming agent at a fixed pressure into a starvation zone of the plasticizing cylinder to retain the starvation zone at the fixed pressure; allowing the molten resin to be in the starved state in the starvation zone; bringing the molten resin in contact with the pressurized fluid containing the physical foaming agent at the fixed pressure, in the starvation zone in a state in which the starvation zone is retained at the fixed pressure; and molding the molten resin having been brought in contact with the pressurized fluid containing the physical foaming agent into the foam-molded product.

The present invention relates to a method of controlling a step of a process carried out by a machine. The invention is characterized in that a sensor is used to measure a variable characteristic with an exponential course for a step, and with the aid of several consecutive measurements of the characteristic variable a time constant of the exponential change is determined, and the step is ended after it has been carried out for a period of time corresponding to a predetermined multiple of the time constant.
