SAFOAM FPN3-40 is commonly used to create a fine cell structure for medium and low-density foam applications. SAFOAM FPN3-40 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 very smooth surfaces.

SAFOAM FPN3-40 offers the following 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
• Creates white foams
• Enhances surface appearance
• Eliminates 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

FPN3-40 is compatible with a variety of resins mainly PS, ABS, HIPS, and PP. Request your sample today and speak with our technical department on running procedures.
