Shieldwerx SWX-213

Pure Polyethylene Neutron Radiation Shielding

Features

Pure polyethylene
Neutron moderator with very high hydrogen content and minimal impurities
Available in slabs, cylinders, pellets and can be easily machined into custom shapes

Introduction

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.
