Para-dichlorobenzene

Polyphenylene Sulfide (PPS) is an engineering plastic that excels in heat resistance, chemical resistance, mechanical strength, and electrical properties, and its demand is growing rapidly for electrical and electronic parts, electrical home appliance parts, and automobile parts. Para- dichlorobenzene (PDCB) is the raw material for PPS, and our refining technology, such as distillation and crystallization, has been useful.

In particular, the combination with a purification column which aims at high purity crystals by washing away the impurities inside of the scraped surface cystallizer and the crystal filling layer without using solid-liquid separator, is called the 4C system. It is a refining technology that has become the core technology of our company, and it has made it possible to produce a product having 99.99% purity or above.
