Borotron® UH/HM

  • 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  

Borotron® UH015/030/050 | HM015/030/050

Borotron UH015/030/050 and Borotron HM015/030/050 are boron loaded PE-(U)HMW grades, specifically developed for neutron shielding purposes in nuclear installations and medical applications. 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. 

Different standard compositions of polyethylene grades with added boron content are part of Mitsubishi Chemical Advanced Materials's Borotron product range:

  • Borotron HM015 [High Molecular Weight PE] content: 1.5 % elemental boron

  • Borotron HM030 [High Molecular Weight PE] content: 3.0 % elemental boron

  • Borotron HM050 [High Molecular Weight PE] content: 5.0 % elemental boron

  • Borotron UH015  [Ultra-High Mol.Weight PE]   content: 1.5 % elemental boron

  • Borotron UH030  [Ultra-High Mol.Weight PE]   content: 3.0 % elemental boron

  • Borotron UH050  [Ultra-High Mol.Weight PE]   content: 5.0 % elemental boron
