Epolene® C-18 is a low density polyethylene wax modified with maleic anhydride that is used in heat seal coatings for paper, foil, and polyolefin films.
Epolene® C-18 is a highly branched, low density polyethylene polymer that has been grafted with maleic anhydride. When used in hot melt coatings it provides excellent heat seal-ability to paper, polyolefin films, and foils. The added functionality of Epolene® C-18 is also useful in hot melt adhesive applications where it can improve hot tack and adhesion to difficult substrates. In addition, Epolene® C-18 is an excellent additive for highly filled color and additive masterbatch. The maleic anhydride grafted to the polymer allows for better compatibility between additives and polyethylene. This allows for increases in additive levels without agglomeration or settling. In addition, Epolene® C-18 is an outstanding dispersion agent and processing aid for color masterbatch. When added in low levels, Epolene® C-18 improves color yield and allows for more efficient production.
