Polymer Tungsten Description
Polymer Tungsten or Tungsten Polymer (also known as Tungsten-filled Polymer) is a composition of various resins and Tungsten Powder which are mixed together through special metallurgical technology. Polymer Tungsten is environmentally friendly. It is non-toxic and recyclable. Tungsten Polymer has high density, high radiation resistance, and high tensile strength. It is easily machined and malleable. Therefore, polymer tungsten is the ideal material for radiation shielding instead of lead.

Polymer Tungsten Application
Polymer Tungsten can be used in:
-Radiation shielding and radiation-protective equipment;
-X-ray inspection device for industrial and medical use;
-ϒ-ray shielding material and substitute for lead fiber mat in nuclear reactor piping systems.
Polymer Tungsten Packaging
Our Polymer Tungsten is clearly tagged and labeled externally to ensure efficient identification and quality control. Great care is taken to avoid any damage which might be caused during storage or transportation.
