IPS technology is based on a continuous mass peroxide-initiated polymerization of styrene in a rubber-styrene solution.

RUBBER SOLUTION PROPARATION
Rubber, after being ground in a mill, is dissolved in styrene in a proper section and then added with chemicals and peroxide in a mixing section.

POLYMERIZATION
The mass reaction occurs in the presence of solvent. This mixture is thus fed to the polymerization section, generally composed by a sequence of two/three plug-?ow reactors; the reaction thermal profle is controlled by thermal oil circulating inside internal coils. The whole reaction section arrangement is custom designed case-by-case, in order to meet specifc requirements.

DEVOLATILIZATION
At the end of the reaction train, the polymer solution is sent to a devolatilization section, operated in two stages in series under vacuum conditions.
The monomer and low-boiling compounds are removed from the polymer, which is fnally sent to the pelletizing unit.
The heat is provided by a thermal oil system. The vapour mixture, recovered by the devolatilization section, is condensed and then continuously recycled to the mixing section. Non-condensed vapours/inert gases from the vacuum system and liquid organic purge from the condensation section are recovered as fuel in a furnace, where thermal oil for the process is heated

PELLETIZATION
The finished polymer is pump to the pelletizing section to covert to pellets.
