Cel-Span® S 310
An excellent shut-down additive to eliminate black specs and char for film applications.

Cel-Span® S 310 is a compounded antioxidant concentrate in HDPE & LLDPE blends to provide thermal stabilization to polymers at high temperatures and during routine maintenance shut-down procedures. Cel-Span® S 310 is an effective shut down stabilizer for all polyolefin resins. It is used to protect these materials from thermal degradation during exposure to processing temperatures maximizing the inherent physical properties of the natural resins. When used at a 5-10% level, Cel-Span® S 310 can be left in extruders, dies, and other process equipment during routine maintenance "shut down and start up" procedures, to prevent unwanted polymer degradation, and help keep the process equipment clean and free of black specs and degradation.
