Vertellus alkenyl succinic anhydride (ASA) technology provides a fast reaction rate with cellulose and develops efficient hydrophobicity in a range of pulp furnishes.  As an internal size, ASA has less impact on final product friction properties as compared to competing for AKD.

Products in the BERSIZE® ASA Series is the most suitable choice for use in precision sizing with recycled packaging (gluing and converting concerns) grades and printing & writing grades (ink/water balance).  Gives the papermaker the ability to size systems down to 5.5 pH​ and presents the lowest cost-in-use sizing chemistry for most wet-end systems.  BERSIZE® ASA technology is adopted for use by many leading companies in the Paper industry. 

PENTASIZE® ASA technology provides for an equally high-performing sizing agent and has an alternate supply chain well-suited to servicing the EMEA (Europe, Middle East, and Africa) papermaking markets.
