Struktol’s newest additives provide improved processing characteristics and performance

Struktol Co. of America, a leading global supplier of polymer additives based in Stow, OH, is presenting an expanded product line for engineered plastics this week in Orlando, FL. These new additives, says the company, have been designed to provide greater processing and performance capabilities for compounders, processors and end users. The company can be found at booth S-27082.

Struktol is showcasing its new, high-efficiency lubricant and viscosity reducer for nylon 6 and nylon 6,6 compounds, marketed under the name Struktol TR 063A. Boasting a novel chemistry that makes it compatible with polyamides, the product can be added directly at the compounding stage or by the processor during part manufacturing. In pellet form, it can be easily added to extrusion or injection molding machines, offering compounders and processors a cost-effective process additive that can significantly improve throughput and efficiency.

Additionally, Struktol is presenting StruktoL TR 044W, a product that provides a combination of viscosity reduction and mold release characteristics for polycarbonate resins and compounds. Loading levels as low as 0.2% result in increased melt flow and allow for significant improvements in mold filling and release. The product is highly suited to clear applications, as only minimal haze development occurs, even at higher loading levels. The improved processability can result in lower molded-in stress in injection molding applications that often will mean better part performance. The product is also effective in highly-filled polycarbonate compounds, providing improved dispersion and lower viscosities.

Another new product, StruktoL TR 077, is claimed to enhance metal release, thus providing additional benefit to processors of nylon 6 and 6,6. It exhibits added external lubricity for both extrusion and molding applications. It is a replacement product for applications where traditional powder zinc stearate is currently used, offering superior processing, as well as better handling due to pastille product form, according to the company. It also works well in many other polymer systems including polystyrene, concentrates, thermosets, and many olefins, and meets the requirements of many FDA applications.
