Description
SAFOAM PSN-510 is a medium temperature masterbatch of an endothermic chemical nucleating agent for the creation of a fine foam structure in thermoplastic extrusion applications. SAFOAM PSN-510 improves melt tension and melt flow. It is generally used in direct-gas polystyrene applications using hydrocarbon gases, CFC, HCFC, CO2, NO2, or any combination of the above.
Unique Powder/Carrier Benefits
All SAFOAM powders are microencapsulated with special surfactants, which result in:
· Improved bubble stability
· Slowed moisture absorption and diffusion rate
· Improved CO2 solubility rate
· Extended shelf life
· Excellent dispersion

Main Uses
Recommended for styrenic-based thermoplastics that reach the decomposition temperature during processes. SAFOAM PSN-510 is commonly used to create a fine cell structure for medium density foam applications. SAFOAM PSN-510 can be used in various applications in conjunction with gas counter-pressure and gas assist molding technologies. The most common application is in low-density polystyrene foam extrusion for the creation of nucleating sites and very smooth surfaces.
