Release agents internal variety

Fatty amides. Fatty amides possess unique mold release properties. Simple primary fatty amides are used as slip and mold release agents primarily in polyolefins but also in a variety of other polymers. The more complex bis-amides, such as ethylene bis-stearamide, offer mold release as well as internal and external lubricity functions in materials such as PVC and ABS. 

There are numerous suppliers of lubricants and mold release agents as a result of the variety of chemistries that perform the function of internal and external lubrication. The suppliers are generally large specialty chemical companies that sell the particular chemistry to a wide variety of end-use applications. The amount of material sold to fimc-tion as a lubricant or mold release agent for plastics is typically small in comparison to each company s total sales. Table 4.19 shows the major global suppliers of lubricants and mold release agents by type.

Polycarbonate resins are available in formulations with a wide variety of additive options, such as UV stabihzers and mold-release agents. More recently, manufacturers have expanded their portfohos to include materials that are compliant with the major international environmental standards.
