Resulting Properties
Hot Melt Adhesive Based on Polyolefin Elastomer (Conventional Application Temperature) have good thermal stability (minimal color changes and reduced gel formation on standing in the melter). Melt viscosities can have a wide range due to molecular design and additives. The formulations above describe hot melt adhesives for general purpose bonding of packaging, non-woven hygienic products, and graphic arts. These formulations offer a wider service temperature range than EVA based hot melt adhesives. The source of this formulation is Dow Chemical.
