Borated UHMWPE Sheet for Neutron Radiation Shielding
Product description
Boron-containing polyethylene is a highly effective anti-neutron shielding material with good catalytic activity and low corrosivity to equipment, and will not cause environmental pollution. Compared with traditional metals and concrete, boron-containing polyethylene composites have the characteristics of low density, good attenuation curve, convenient use, low cost and good processing performance. The polyethylene resin has high content of H element and good anti-irradiation performance. It is effective for neutron radiation in neutron and gamma mixed radiation fields to meet the needs of different energy levels of radiation. Usually choose 5% boron-containing polyethylene shielded fast neutrons with a thickness of 10-20CM to achieve your desired protection. For example, the polyethylene plate thickness 150MM + 10% boron carbide technical indicators are: (10% by weight
ABOSN Radiation Shielding boron loaded UHMWPE sheets was specially designed for nuclear shielding applications and is used in a variety of applications including high-intensity X-rays, cancer treatment facilities, nuclear submarines, and nuclear power plants.
5% 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 behavior at high temperatures and its superior impact strength and wear resistance.
