Material Notes:

This is a special grade consisting of spherical beads of a blend of polystyrene-polyphenylene ether containing pentane as expansion agent, typically used for medium density foam with improved thermal resistance.Applications: This grade is used for medium density foam with wall-thickness generally greater than or equal to 10 mm and with improved thermal resistance. Typical applications include hot-water insulation, pipe-insulation and automotive parts (interior and exterior).Processing of DYTHERM beads on pressurized batch pre-expander is recommended. It can be process on a continuous pre-expander when higher densities are acceptable.This grade should not be used for food contact applications.Information provided by NOVA Chemicals.
