ROSINO has developed business centered on fine chemical products essential in people's everyday lives based on the various synthesis technologies that the company boasts. These chemicals are designed to improve the manufacturing process and to add high-value features in terms of resistance, performance, safety, color. The following products are classifed by their application field:

ROSINO‘s antioxidant products provide excellent  stability against both thermal degradation  and scorch. The stabilizer allows production  of extremely clean XLPE. It is compatible  with PE and does not recrystallize in the end  product. Phenox 300 & Vulctac Tb7 are also be used as disproportionation catalyst for rosin ester; Vultac Tb7 is a nitrosamine-free vulcanizing agent, which gives ultra-fast curing speed.

The polycarbonate most used is manufactured by condensation polymerization between bisphenol A and either carbonyl chloride or diphenyl carbonate. Although the polycarbonate derived from bisphenol A is easily the most widely used polycarbonate, Modified co-polymers have been developed in which substituted bisphenols are added and reacted with diphenyl carbonate. The resulting polymer enhanced flame resistance or improve the polycarbonate's resistance to heat. Polysulfone is made by the reaction of the disodium salt of bisphenol with 4,4'- dichlorodiphenyl sulfone. These resins are heat-resistant plastics can be molded to tight tolerances and exhibit low creep under a sustained load at elevated temperatures and have excellent oxidation resistance and compressive strength. 

All the bisphenols, sulfoxides, sulfones in our prouct line are available to the typical or modified ploycarbonate & polysulfone preparation process.
