Title: Akihiro Maruyama: Innovator in Phenolic Resins
Introduction
Akihiro Maruyama is a notable inventor based in Yokohama, Japan, recognized for his contributions to the field of phenolic resin technologies. With a total of two patents to his name, Maruyama has made significant strides in creating advanced materials that demonstrate unique properties.
Latest Patents
His latest patents focus on foamable phenolic resin compositions and the processes for their preparation. One key innovation involves a method for producing resol type phenol resin foams where the starting materials are created by blending a resol type phenol resin with blowing agents and catalysts. A unique feature of this method is the combination of low molecular weight resol type phenol resin, with a number average molecular weight of less than 200, with a high molecular weight resol type resin, greater than 200, in a precise weight ratio of 5/95 to 80/20. This innovative approach results in phenolic resin foams that excel in adhesion and fire-proofness, and can cure rapidly, making them ideal for applications such as sprayed-in-place foaming. Furthermore, these resins can be integral foamed with rigid urethane resin foam layers, leading to foamed laminates that offer exceptional thermal insulation and fire-proof properties.
