30% Boron by weight to shield neutrons, are boron loaded PE-(U)HMW grades. The high hydrogen content of PE (U)HMW makes it very suitable for slowing down fast neutrons to lower energy thermal (slow) neutrons, which are  then absorbed by the added boron compound.

Whereas both PE-HMW and PE-UHMW are suitable for neutron shielding,  PE-UHMW is often preferred because of its better deformation behaviour at high temperatures and its superior impact strength and wear resistance.

The boron-containing polyethylene board produced by our company is mainly used in various nuclear power plants, nuclear reactors, petrochina, military, Chinese academy of sciences, research laboratories, hospitals and nuclear experimental products tanks, neutron beam collimators, neutron traps, control rod materials for nuclear reactors and nuclear shielding materials and other research fields.As a shielding material for absorption of neutrons, gamma rays and radiation.
