Japan's Chungcheon Chemical Industries and Sumitomo Chemical Industries announced on November 29th that they jointly developed acrylic resin (acrylic resin) foaming technology, mainly in combination with Sumitomo Chemical's acrylic resin technology and the Chungchi chemical industry. , foaming technology, has now 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.
