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.
