| Safoam RPC |
 |
SAFOAM RPC is a high temperature endothermic chemical nucleating and blowing agent for moisture-sensitive polymers.
It is used for the creation of a foam structure in thermoplastic injection molding and extrusion applications.
It is commonly used in custom compounding operations for the creation of fine size cells in structural foam and for fine cell nucleation in direct gas applications.
SAFOAM RPC has water molecule scavengers that are designed with special buffering agents to be pH neutral.
Recommended for Nylon, PC and Polyester based thermoplastics, but may be used in any thermoplastics or thermoset material that reaches the decomposition temperature during processing.
SAFOAM RPC is commonly used in custom compounding and is recommended for moisture-sensitive resins.
Powder processors will benefit from the better economics of SAFOAM RPC over pelletized SAFOAM.

- Increases extrusion output rate
- Achieves significant weight reductions
- White foams
- Enhances surface appearance
- No pin holes
- FDA approved뻮afe for food contact
- pH balanced and buffered formula
- Improves process economics |
