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 improved thermal resistance. Typical applications include hot water insulation and automotive parts (interior and exterior).Processing of DYTHERM beads on pressurized batch pre-expanders is recommended. DYTHERM 140R can be processed on a continuous pre-expander when high densities are acceptable. Detailed processing advice is given in the DYTHERM bulletins, available from your local NOVA Chemicals company.This grade should not be used for food contact applications.Information provided by NOVA Chemicals.
