Applicable Base Polymer Properties
The amorphous polyolefin based hot melts are widely used in such areas as packaging, non-wovens, and product assembly. They are suitable for adhering paper or foil to a variety of substrates. The products are tailored copolymers of ethylene, propylene or 1-butene and exhibit a range of melt viscosities, needle penetrations and softening points, surface tackiness, and open times. Incorporation of 1-butene gives copolymer products long open times and low softening points of around 107°C.
