Overview
EBAC+® SP1903 is a high-quality EBA copolymer with acrylate functionality. It contains 18% ethylene butyl acrylate for improved impact resistance, enhanced processability, and high flexibility using extrusion, molding, and cast and blown film equipment. Its noncorrosive nature makes it compatible with a range of polymers, providing enhanced adhesion and high filler acceptance. It is recommended for applications where elasticity and flexibility at various temperatures are essential, including heat seal layers, flexible films, and blown and cast films, due to its melting point of 101°C and brittleness temperature of less than −73°C.
