PAC is an inorganic chemical having polymeric structure soluble in water.
Why to use RIP-PAC rather than the alum in paper sizing?
Less quantities usage due to higher charge given to PAC.
COBB adjustment is very easy.
Easy to handle due to liquid
Power and men power saving in production.
No sludge formation and its carried.
Safer to health.
Generate effluents is better.
Consistent quality.
Alum is made from ore which can contains any type of hazardous metals whereas RIP-PAC is safer.

Function:
To boost drainage rates especially in neutral and alkaline papermaking, to help with certain retention aid strategies, and for neutral sizing with certain rosin-based emulsion products. PAC products of low (9 to10%) and medium (12 to18%) are commonly used in papermaking applications.
