Poly Aluminium Chloride Pac
Poly Aluminum Chloride (RIP-PAC)
Paper Sizing Chemical
Chemical Formula: (Aln(OH) mCl3n-m)X
Cas : 1327-41-9
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 to 10%) and medium (12 to 18%) are commonly used in papermaking applications.
