Applications

STARFLEX EVA is a polymer for the modification of bitumen, to be done in special plants. STARFLEX EVA can be used also added directly in the mixer of the asphalt production plant obtaining polymer modified asphalt.

Advantages

STARFLEX EVA is used in order to manufacture asphalt for applications where are required high characteristic of mechanical resistance in terms of higher stability both to the deformation and to the compression.

Modality of Use

STARFLEX EVA dosage varies in accordance to the modification required, normally the dosage is made from 3% to 7% of the bitumen weight. The use of STARFLEX EVA can be done by using a dosing screw or manually.

Indicative laboratory values obtained with a bitumen base 70/100.
