Abstract
The polyolefin with organoclay and fluoropolymer additives improves the processing characteristics of the polyolefin for melt extrusion. Between about 200 and about 1,000 ppm/weight organoclay (0.02-0.1 percent by weight) and between about 200 and about 1,000 ppm/weight (0.02-0.1 percent by weight) fluoropolymer are mixed with a polyolefin resin, such as high-density polyethylene (HDPE), in order to improve the extrusion processing characteristics of the polyolefin.
Claims9
A polyolefin compound for processing by extrusion, comprising a composition having:
- between about 0.02 and about 0.1 percent by weight of an organoclay additive;
- between about 0.02 and about 0.1 percent by weight of a fluoropolymer;
- and
- a polyolefin resin forming the balance of the composition.
A method of making a polyolefin composition, comprising the steps of:
- grinding a polyolefin resin;
- mixing the ground polyolefin resin with an organoclay additive;
- mixing a fluoropolymer additive with the ground polyolefin resin and the organoclay to form a polyolefin composition having the organoclay between about 0.02 and about 0.1 percent by weight and the fluoropolymer between about 0.02 and about 0.1 percent by weight, the balance being the polyolefin resin;
- and
- blending the composition to compound the additives with the polyolefin resin.
