POLIMAXX® 321F
- Chemical Family
- Styrenics
POLIMAXX®321F is a regular grade (Standard grade) Expandable Polystyrene (EPS) containing pentane as blowing agent. This grade is developed to meet the demand for fast molding cycles in vacuum machine and conventional molding machines. This grade is particularly well suited for the manufacturer of EPS part products, width part wall thickness above approximately 10 mm. It is also widely used for production of insulation boards and panel, block molded or produced in continuous molding machines.
