Acrylic resin foaming technology

Recently, Japan's Chungcheon Chemical Industry and Sumitomo Chemical Industry Co., Ltd. announced that they have jointly developed a foaming technology for acrylic resin (acrylic resin), which is mainly based on Sumitomo Chemical's acrylic resin technology and its integration with Bell Chemical Industries. Bubble technology, has begun to make small beads (beads) test sale.
Although there are currently foamed products of PMMA/PS copolymers, it is the world's first in the foaming of acrylic resins. At the same time, this technology can use existing foaming EPS forming equipment and is scheduled to be officially launched in the first half of 2002. After 5 years, it is estimated that there will be a turnover of 1 billion yen per year.
When the new product is burned, the amount of smoke and residue is very small, and it is suitable as a model for extinction casting of precision forging of automobile engines and other castings. At present, this application mainly uses EPS or PMMA/PS copolymer foam.
In addition, acrylic foam resin can be used outdoors for a long time due to its excellent weather resistance, and can be used in direct agricultural materials or various cushioning materials, structural materials, shape materials, etc., such as honeycombs, hydroponic cutting containers, and nursery equipment. Disk and so on.
