History of Yamahachi Chemical
History
Your technical solution, Custom porous plastic
Yamahachi Chemical began operations in 1969 as a small manufacturer of plastic molding parts for automobiles and electrical appliances in Gamagori, Aichi Prefecture. Today, the company is engaged in the production and development of porous plastic and their components for customers in various fields.
In 1977, the company started its own research and development of porous plastic and established the manufacturing technology of porous material for pre-inked stamps, now called “flash foam”. At the same time, the company collaborated with leading stamp manufacturers to invent some advanced simplified stamp making systems that worked well with the “flash foams”. In the 1980s, the company began to use its porous manufacturing technology to develop porous nibs for art markers. These porous products, which are still used in the global stationery industry today, are continually updated to improve quality and technology.
Today, we have established research, manufacturing and sales facilities in both Japan and China to supply porous products to customers worldwide beyond stationery applications. With the manufacturing technology and special knowledge of these functional porous plastic with the basic performance such as absorption, application, diffusion, venting and wicking, we will continue to work diligently to develop unique products and materials that our customers need as their technical solution.
