Safoam PE-50 |
|
SAFOAM PE-50 is a medium temperature olefinic masterbatch of an endothermic chemical nucleating and blowing agent for the creation of a foam structure in thermoplastic injection molding and extrusion applications. SAFOAM PE-50 contains 50% SAFOAM P powder and 50% special olefinic surfactants and carrier resins, 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 olefinic based thermoplastics that reach the decomposition temperature during injection molding or extrusion. SAFOAM PE-50 is commonly used to create a standard cellular structure for medium density foam applications. SAFOAM PE-50 can be used in various structural foam applications in conjunction with gas counter-pressure and gas assist molding technologies and in the CoralFoam process. It is also used for processors with short L/D screws or poor mixing capabilities to increase uniformity in the foam extrudate. *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 |
