Abstract

Baker Hughes Incorporated (BHI) announces a new line of polyethylene / polylactide block copolymers. These copolymers are produced via controlled polymerization to yield products with varying amounts of polyethylene and polylactide blocks. The process allows independent control of the polyethylene and polylactide blocks, which allows a wide range of properties. The polyethylene portion can have varied amounts of branching, ranging from essentially no branches (totally linear) to highly branched (hyperbranched). The polylactide content comes from biobased lactic acid and provides improved biodegradability for the new product. The polylactide content can range from <5% by weight up to around 95% by weight.

Polyethylene /Polylactide Block Copolymers for Ceramic Applications

Baker Hughes Incorporated (BHI) announces a new line of polyethylene / polylactide block copolymers.  These copolymers are produced via controlled polymerization to yield products with varying amounts of polyethylene and polylactide blocks.  The process allows independent control of the polyethylene and polylactide blocks, which allows a wide range of properties.  The polyethylene portion can have varied amounts of branching, ranging from essentially no branches (totally linear) to highly branched (hyperbranched).  The polylactide content comes from biobased lactic acid and provides improved biodegradability for the new product.  The polylactide content can range from <5% by weight up to around 95% by weight.

BHI claims the following application benefits:

·         As additives to improve the green strength of molded parts.  The new wax can modify the surface of the ceramic particle to provide improved strength of the molded part before firing.  The new wax can be used at levels up to 5% by weight in the formulation.

·         As additives to decrease defects in molded parts.  The new wax can modify surface of the ceramic particles to provide improved flow within the mold and decreasing the number of defects in the molded parts.  The new wax can be used at levels up to 5% by weight in the candle.

In summary, BHI’s new line of polyethylene / polylactide block copolymers can be used as additives for ceramic applicati...
