  • Use of polyolefin waxes in the field of plastics processing
    Patent number: 7192909
    Abstract: The invention relates to the use of polyolefin waxes as external lubricants and release agents for plastics. Said polyolefin waxes are produced by using metallocene catalysts, whereby the polyolefin waxes are homopolymerizates of ethylene or are copolymerizates of ethylene with one or more 1-olefins, and linear or branched, substituted or non-substituted olefins having 3–18 C atoms are used as 1-olefins. The processable plastic mixtures produced in this manner have a distinctively longer tack-free time and exhibit an improved behavior with regard to mold release.
