In nuclear work and in medical technology applications it is essential to screen the facilities from people and the physical environment around. These jobs generate both particle and electromagnetic radiation. The resulting radiation fields can consist of a combination rapid neutrons, protons, electrons, thermal neutrons, and primary as well as secondary gamma radiation.
Fast neutrons are most effectively stopped by a high hydrogen content such as water, paraffin or polyethanes which contain high levels of hydrogen nuclei. Through repeated collisions with hydrogen nuclei, fast neutrons can be reduced to so-called slow neutrons.
Our Boron-filled polyethylene sheets, Borotron®, offer cost-effective solutions for absorbing neutron radiation.
AB Carlsson & Möller markets Borotron®, a material consisting of stable polyethylene modified with boron. The material can to a great extent eliminate the neutrons through nuclear reaction between the substance boron and neutrons.
Borotron® is available in the grades PE-HMW (High Molecular Weight Polyethylene) and PE-UHMW (Ultra High Molecular Weight Polyethylene), which can handle working temperatures up to +80°C to +120°C.
For higher temperatures, Carlsson & Möller offers a polyethylene with 20% boron and 10% lithium. This material withstands continuous temperature exposure up to +200°C and short-term temperature exposure up to +300°C.
Materials can also be obtained with customer-specified boron additive. For further information, please contact Carlsson & Möller.
For many years, Carlsson & Möller has been an active member of the Big Science Sweden network, which arranges seminars, study visits and workshops. BSS focuses on supplier development and linking Swedish companies to customers in research and development. In Sweden, Carlsson & Möller is an established supplier to, among others, the research facility Max IV and ESS, where we assist with application knowledge and details in advanced machined construction plastics.
We deliver internationally to research facilities such as CERN, which is one of the many customers within the field of research to which Carlsson & Möller delivers advanced construction plastics.
