Material Notes:
Borotron UH and Borotron HM are boron loaded PE-(U)HMW grades, specifically developed for neutron shielding purposes in nuclear installations. 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 Effectively attenuates neutron radiation particles and minimises the gamma radiation released during their capture Very good wear and abrasion resistance High impact strength (particularly PE-UHMW) Excellent chemical resistance Low coefficient of friction Very low water absorption Moderate mechanical strength, stiffness and creep resistance Excellent machinability
