Composition:
VIBATAN PE GAMMA RAY ANTIOX 02695 is a blend of polymeric HALS and antiox agent dispersed in polyethylene, free from fillers, waxes or any other lubricants.

Application:
It is known that in some particular sectors, such as the medical one, it is necessary
to make end-products aseptic: an effective way to eliminate the undesired bacteria is to undergo the end-product a gamma ray treatment.

Unfortunately, these rays provoke a colour change in the treated article (i.e., yellowing).

VIBATAN PE GAMMA RAY ANTIOX 02695 has been expressly designed to stabilize PE end-products and to avoid colour change in the gamma ray treated articles.

The maximum protection is granted if the polymer used in the production of the end-products does not contain phenolic antioxidants, since they are the main cause of
the colour change.

On the contrary, the presence of the phenolic antioxidants may reduce or even cancel the effect of VIBATAN PE GAMMA RAY ANTIOX 02695.
