NUCLEATING AGENT FOR POLYETHYLENES

摘要

The invention relates to nucleation agents for polyethylenes wherein the nucleating agent is composed of one or more finely divided inorganic materials of halloysite that are dispersed throughout the polyethylene to increase the crystallization rate such that the polyethylenes can be more easily extruded, molded with a much shorter cycle time or thermoformed into intricate parts. The most preferred agent is halloysite nanotubular clay.
