Vinamul Receives Patent For Use Of Acrylic Copolymers
The US Patent and Trademark Office has issued a patent to Vinamul Polymers, a business unit of
Bridgewater, N.J.-based National Starch and Chemical Co., for the use of acrylic copolymers that
add tailorable abrasive functionality to nonwoven wipes products. The resulting NACRYLIC ABX-30
acrylic polymer product is designed to meet the growing demand for abrasive, scrubbing and scouring
wipes in household and personal-care applications; and in institutional, food service and
According to Vinamul, the polymers abrasive qualities are derived from the polymer itself, which contains no hard particulates or post-added grit, making it safe for use on any surface. In addition, the polymer provides wipes with high wet strength, cationic disinfectant compatibility and a durable hard-surface cleaning functionality.
The NACRYLIC ABX-30 emulsion was designed to resist penetration into fabrics during application in order to impart effective and durable dry and wet abrasion properties to traditional wipe substrates such as airlaid, spunlaced, and needlepunched nonwovens. Manufacturers can apply the polymer using standard liquid bonding methods, including spray, foam, print and saturation.
