Styrenics Resin (GPPS, HIPS, SAN, ABS)

Summary

TOYO and Mitsui Chemicals, Inc. (MITSUI) have been jointly promoting the R&D and the licensing of TOYO-MITSUI PS PROCESS based on the continuous bulk polymerization technology. TOYO-MITSUI PS PROCESS covers all of styrenics resins, i.e., 1) General Purpose Polystyrene (GPPS), an amorphous, colorless polymer of styrene as sole monomer, 2) High Impact Polystyrene (HIPS), a graft polymer in which synthetic rubber is chemically bonded to GPPS resulting in having impact strength, 3) Styrene Acrylonitrile copolymer (SAN), a copolymer of styrene and acrylonitrile resulting in having chemical resistance, and 4) Acrylonitrile Butadiene Styrene Resin (ABS) that has both impact strength derived from poly-butadiene rubber and chemical resistance derived from acrylonitrile.

GPPS: General Purpose Polystyrene
HIPS: High Impact Polystyrene
SAN: Styrene Acrylonitrile Copolyme
ABS: Acrylonitrile Butadiene Styrene Resin

Feature

TOYO-MITSUI PS PROCESS, a continuous bulk polymerization process having specially designed reactor and devolatilizer using thermal initiation polymerization and precise control of the degree of polymerization as basic technologies, has the following feature.

  • Simple process scheme and compact plant layout.
  • Simple and easy operation with less grade change time化
  • Environmental friendly
  • Less wastes
  • Stable operation and appropriate countermeasures for emergency
  • Low raw materials/utilities consumption

Especially the ABS process is an environment-friendly process compared with the competent technology in terms of negligible amount of acrylonitrile in the waste water.
