Cross-linking Trimer Acid produces toughness in polymers Emsorb® Esters offer superior color and color stability
T h e functionality of three carboxyl groups in Empol® 1043 Trimer Acid gives a cross-linking action which produces a toughness t h a t ' s highly desirable in specialty resin systems.
T h e superior color and color stability of E m s o r b Sorbitan and Ethoxylated Sorbitan Esters is demonstrated by t h e d a t a shown below. E m s o r b Esters are derived from t h e finest quality E m e r y fatty acids, and manufactured to exacting s t a n d a r d s , t h u s assuring t h e batch-to-batch purity and uniformity essential for consistency and perfection in finished products.
