 Introduction

 

Shieldwerx SWX-213 Pure Polyethylene Neutron Radiation Shielding●  Pure Polyethylene Neutron Radiation Shielding

●  Used to Thermalize Fast Neutrons

●  Very High Hydrogen Content and Minimal Impurities

●  Available in Slabs, Cylinders, Pellets, Easily Machined

 

Shieldwerx SWX-213 is high purity virgin polyethylene used to thermalize fast neutrons, primarily for experimentation where it is desirable to produce a thermal neutron flux from a higher energy field. SWX-213 has minimal impurities that might absorb thermal neutrons. This material can be easily machined into complex shielding form factors and is available in virtually any shape or configuration.
