Apr. 18, 2018 – Colour and specialty chemicals company Archroma is highlighting its solutions this week at TAPPI’s PaperCon 2018.
At the show, Archroma is introducing its new patented disulfonated fluorescent whitening agent (FWA), Leucophor ACK liquid, to North American papermakers. Described as bringing a new ecological focus to the field of FWA, the company says the ultra-concentrated Leucophor ACK liquid is free of urea and other additives that increase nitrogen load and COD in back- and wastewaters, while its higher actives content brings advantages of fewer deliveries, reduced freight costs, lower greenhouse gas emissions and better use of storage capacity. According to the company, Leucophor ACK liquid enables brilliant whiteness in stock and coating applications and complies with major international eco-labels.
Meanwhile the new patented, urea-containing alternative, Leucophor ACS liquid, is described as retaining the advantages of fewer deliveries, reduced freight costs, better use of storage capacity and a lower carbon footprint.
Archroma will also present the Cartastrength HWM liq, describing it as providing high performance wet strength in particular to tissue paper, coming in high solids form for low shipping and storage costs. Cartastrength HWM liq is FDA compliant and displays lower AOX (Adsorbable organic halides) than typical Grade 1 products.
