ZeMac™ E400 Copolymer
ZeMac E400 Copolymer is an alternating copolymer of ethylene and maleic anhydride with very high molecular weight; Mw of 300,000. The product is 100% water soluble and can be reacted with alkalis, alcohols and amines to form corresponding salts, esters and amides.
ZeMac Copolymers act as emulsion stabilizer and control mean particle size (MPS) & particle size distribution (PSD) and controlling release of active in liquid detergents, softeners, PCMs and other encapsulants in microcapsules.
ZeMac is used in various microencapsulation applications with wall forming systems such as melamine formaldehyde, polyurea, polyurethane, etc. ZeMac provides emulsion stability while simultaneously controlling particle size distribution. This results either in controlled release of the active (fragrance), or cross-linking to prevent release of the active (phase change materials).
ZeMac Copolymers act as emulsion stabilizer and control mean particle size (MPS) & particle size distribution (PSD).
