SAFOAM P-50 is a medium temperature styrenic masterbatch of an endothermic chemical nucleating and blowing agent for the creation of a foam structure in thermoplastic injection molding and extrusion applications.
SAFOAM P-50 contains 50% SAFOAM P powder and 50% of a special surfactant package based on a styrenic resin and an SEBS rubber, which improve melt tension and melt flow.
It is commonly used in injection molding for the creation of structural foam composites.
In extrusion operations, it is used for the creation of standard size cells in medium density extrudate.
Recommended for styrenic based thermoplastics that reach the decomposition temperature during injection molding or extrusion.
SAFOAM P-50 is commonly used to create a standard cellular structure for medium density foam applications.
SAFOAM P-50 can be used in various applications in conjunction with gas counter-pressure and gas assist molding technologies, but its main application is as a nucleant in direct gas polystyrene extrusion.
*Benefits:
- Creates a standard closed-cell foam structure
- Improves melt flow & dispersion in thermoplastics
- Improves melt strength
- In-line paintable
- Improves cycle time in injection molding
- Increases extrusion output rate
- Achieves significant weight reduction
- White foams
- Enhances surface appearance
- No pin holes
- FDA approved ?safe for food contact
- pH balanced and buffered formula
- Improves process economics
- Reduces VOC's of direct gas polystyrene extrusion
- Improves post-expansion in direct gas polystyrene
- Improves flex and elongation and reduces brittleness |
