Estimating the term…
Amorphous propylene-ethylene copolymers are described herein that can include high amounts of ethylene and exhibit desirable softening points and needle penetrations. The desirable combinations of softening points and needle penetrations in these propylene-ethylene copolymers allow them to have a broad operating window. Due their broad operating window, the propylene-ethylene copolymers can be utilized in a wide array of applications and products, including hot melt adhesives.
An adhesive comprising a propylene-ethylene copolymer, wherein said propylene-ethylene copolymer comprises at least 10 weight percent of ethylene and a softening point of at least 99° C.
An adhesive comprising:
