Resin Modifiers, Acid Modified Polyolefin

UMEX Products
Preface
UMEX products are a series of acid modified polyolefin.
These products have a higher degree of modification and lower melt viscosity compared withconventional acid modified polyolefin. Therefore the products at low amount of addition improve thedispersibility of pigments, filler and wood flour to the polyolefin resins. And the products improve theadhesion of the polyolefin resins and other materials. Moreover, the products are very effective as amodifier for hot melt adhesives and asphalt.

Precaution Against Mishandling· When the UMEX products are excessively added to the resin, these products may have negative
effects on resin’s physical properties. Test the effects on each of the physical properties beforehand
to ensure that there are no problems.
· As shown in Table 2-b on page 7, the compatibility with certain molding resins is insufficient,
therefore the transparency may be affected. Before using the UMEX products, confirm thecompatibility with resins.
