Paper
Paper manufacturing depends on a specific mix of raw materials to hit its production, cost, and quality targets. PlaxRaw supplies these materials with consistent specifications and reliable batch-to-batch supply.
Applications
Calcium carbonate and kaolin fillers boost brightness, opacity and smoothness needed for sharp, high-quality printing surfaces.
Calcium carbonate filler reduces fiber content and cost while maintaining the stiffness and bulk needed for board grades.
Fine, high-purity calcium carbonate and kaolin grades support softness and bulk without compromising tissue strength.
Fine kaolin coating clay delivers the gloss, smoothness and ink holdout required for premium coated and specialty grades.
Sodium sulphate is added as make-up chemical in the kraft recovery cycle to replace sulfur and sodium losses during pulping.
Bars show a quick approximate share in a general formulation for this industry — actual ratios vary by product and production line.
