A new lubricant from Struktol Co. of America, Stow, Ohio, is designed to reduce compound viscosity, significantly improve metal release, and enhance dispersion of fillers and reinforcements in nylon 6 and 66. The product, designated TR 063, boasts a novel chemistry that makes it highly compatible with polyamides and superior in performance to alternative lubricants, the company says.
Struktol reports dramatic reductions in die build-up during compounding and strand pelletizing, and extremely good overall processing in extrusion and injection molding of the finished compounds. Reduced die build-up allows compounders to run longer without concern for contamination or discoloration—especially important with natural or light-colored compounds. Physical properties are minimally affected by TR 063, unlike competitive lubricants, Struktol claims.
In filled or reinforced compounds, TR 063 provides a balance of viscosity reduction and dispersion improvement, and minimal interaction with coupling agents for glass fiber. In pellet form, TR 063 can be added at the compounding stage or by the processor during final molding or extrusion.
