Abstract

Baker Hughes Inc. (BHI) announces a new line of synthetic waxes. These waxes are produced via a technology that better aligns with the EPA’s principles of Green Chemistry and is more energy efficient compared to traditional polymerization processes. This novel process is designed to produce linear, sharp melting waxes with very narrow molecular weight distributions without the need for distillation. These synthetic waxes have a polydispersity as low as 1.01, but typically 1.1 or less. They have molecular weights (Mn) that range from 400 to 1000 with melting points ranging from 65 ◦C to 105 ◦C.

Sharp Melting Synthetic Waxes for use as Mold Release Agents

Baker Hughes Inc. (BHI) announces a new line of synthetic waxes.  These waxes are produced via a technology that better aligns with the EPA’s principles of Green Chemistry and is more energy efficient compared to traditional polymerization processes.  This novel process is designed to produce linear, sharp melting waxes with very narrow molecular weight distributions without the need for distillation.  These synthetic waxes have a polydispersity as low as 1.01, but typically 1.1 or less.  They have molecular weights (Mn) that range from 400 to 1000 with melting points ranging from 65 ◦C to 105 ◦C.

BHI claims the following application benefits:

·         As components of external mold release formulations to provide release for plastic or rubber molded parts.  The formulations may be water based, solvent based, hybrid systems with both water and solvent, or 100% solids.  The formulations are applied to molds by spraying, wiping, or other means of coating the surface.  The new wax can be used at levels up to 80% of the external mold release formulation by weight.

·         As internal mold release formulations to provide release for plastic or rubber molded parts.  The new wax can be injected with the product into a mold, or added to the product prior to the mold.  During the molding process the new wax migrates to the surface of the part to improve the release from the mold.  The new wax can be used alone or in conjunctio...
