Radiation protection 5% Boron Boron-polyethylene Neutron Shielding BPE Sheet
Boron polyethylene shield (borated polyethylene shielding box) of boron polyethylene materials according to use need to customize, used for shielding radioactive source radiation shielding, in boron polyethylene shield, boron can absorb effect, of boron neutron reaction cross section is larger, in has not happened before the reaction of hydrogen boron neutron can be fully absorbed, Thus play a complete shielding role.
Boroned Polyethylene Board Advantages:
- Good radiation resistance
- High wear resistance
- Good self lubricity
- High impact resistance
- Good electrical insulation
Product Specification:
Instead of a portable shield, the plate is used as a gasket and electrical insulation in various hollow structures or devices whose housing is protected by a casing (the plate is placed between the housing and the casing or is tightly lined on the outside of the object).
| Project | Unit | Test Result |
| Notched Izod Impact | ft. lbs/in.2 | No Break |
| Vicat Softening Temp. | ºC (ºF) | 89ºC (192ºF) |
| Tensile Strength @ Break | % | >140 |
| Elongation @ Yield | p.s.i. | >300 |
| Shore Harness | ShoreD | 64 |
| Flexural Modulus | p.s.i. | 3000 |
The easiest way to target the use of borinated polyethylene is to choose a suitable size plate and immediately use it as a mobile shield.

Composition of borated polyethylene :
Borated polyethylene is manufactured according to TU 20.16.10.111 – 012. – 27395268 – 2021. According to the provisions of this document, the boards consist of high-molecular polyethylene. The minimum concentration of boron is 3%, the maximum is 30%.There are three molecular carriers of boron:
- amorphous boron;
- chemically pure boron carbide;
- the composition of boron carbide with the isotope B10.
The following requirements are imposed on the content of boron in polyethylene, depending on the brand:
- 3% (BPE-3)
- 5% (BPE-5)
- 7% (BPE-7)
- 8% (BPE-8)
- 10% (BPE-10)
- 12% (BPE-12)
- 20% (BPE-20)
- 30% (BPE-30)
BPE boards are allowed to operate under reactor irradiation conditions and in environments heated to 100 ° C. The limit value of relative humidity is 100%. It is not prohibited to use in water, including sea, if the minimum temperature does not fall below -2 °C and does not rise above +30 ° C.
Application:
Borated polyethylene is a product specially designed for nuclear shielding applications. The material employs 5% Boron by weight to shield neutrons in a variety of applications including high intensity X-rays, cancer treatment facilities, hospitals, nuclear submarines and nuclear power plants.
