JCPEP is a pure, high molecular weight, polyethylene neutron shielding, frequently used as a moderator where it is desired to slow fast neutrons down to thermal energies for experimentation. In these applications, it is highly desirable to maximise the hydrogen content and minimise any impurities, especially those that might absorb neutrons. We can supply high purity virgin polyethylene for this application in a variety of shapes and sizes.
