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 Investment Casting, Phase Change Materials, and Thermostat Wax applications

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 investment casting waxes or components of investment casting waxes to provide the desired properties for molding and casting, including but not limited to, low molten viscosity for consistent mold fill, controlled shrinkage on cooling, and shorter cycle times.  The new wax can be used at levels up to 100% of the casting wax by weight.

·         As phase change materials or components of phase change materials for capture and release of latent heat at a targeted temperature range.  The narrow melting range of the new waxes can be used to modify the melting range of the phase change material to capture or release heat over a range of temperatures.  The new wax can be used at levels up to 100% of the phase change material by wei...
