Polystone® D nuclear black
PE — PE-HD - PE 500
Polystone® D is a high-molecular polyethylene (PE-HMW/PE 500) which is outstanding for its good mechanical properties such as scratch- and cut resistance and excellent acid resistance. The material is used in various branches of industry such as the foodstuffs and bottling industry or in medical technology.
Polystone® D nuclear has been developed specially to shield against neutron radiation in the nuclear industry. The product contains boron to absorb thermal neutrons. The boron concentration can be adjusted to meet customer's needs.
