Changing the marking

Dear colleagues, partners, friends!

We remind you that from January 1, 2019 entered into force DSTU (Ukrainian national standards) B EN 13163: 2012, in connection with which ceased to be valid GOST (Interstate Standard) B.2.7-8-94.

The current normative act clearly defines the standards for expanded polystyrene boards and their marking. Therefore, EPS (international labeling) is replacing the EPS-C.

Detailed information about the brands of polystyrene foam and their density are shown in the table.

Be careful and move to the new standards with us to avoid confusion! We wish you success and hope for fruitful cooperation!
