Polymer Tungsten (also known as Tungsten-filled Polymer) is a composition of various resins and Tungsten powder which are mixed through special metallurgical technology. The resins can be ABS (acrylonitrile butadiene styrene), PP (polypropylene), PBT (polybutylene terephthalate), PA (polyamide), PU (polyurethane), and TPE (thermoplastic elastomer), etc. It’s an ideal substitute of lead for radiation protection.

Properties of T&D polymer tungsten

-High density: ≥11.34 g/cm³

-Perfect radiation shielding performance: Tungsten has comparable radiation shielding ability as lead but is much healthier than lead. To date, many manufacturers, especially those in medical industry, are trying to replace lead radiation shielding products with Polymer Tungsten products.
-Good flexibility and excellent workability: The Polymer Tungsten sheets can be cut or holed with household scissors and formed into shapes with various curved surfaces.
-Healthy and environmentally friendly: The Polymer Tungsten is made of non-toxic & recyclable materials and produces no pollution to the environment.

Application of T&D polymer tungsten
•X-ray inspection device for industrial and medical use
•Radiation shielding and radiation-protective equipment
•Consumer-use products such as raw material for vibration suppression, weight, acoustic (audio) isolation, etc. because of characteristics of enabling 3-dimensional forming
•γ-ray shielding material and substitute for lead fiber mat in nuclear reactor piping systems
•Medical radiation collimator

Polymer Tungsten is formed by the tungsten powder and the polymer. It’s a good substitute material for lead. We can offer the granules, tubes, sheets, and X-ray protective aprons on request.

· Perfect radiation shielding performance against the X-ray and the γ-ray.

· Good flexibility like the rubbery and good flex fatigue resistance.

· Soft, smooth, and easy to cut.

· Non-toxic, non-hazardous, and no pollution.

Application: The tungsten polymer is utilized in many shielding applications, such as medicines, nuclear energy, aerospace, X-ray protection, and the sports.

Polymer Tungsten is a composition of various resins and Tungsten powder which are mixed together through special metallurgical technology. Compared with other materials, tungsten poly has its own properties; it can be easily machined, has high radiation resistance, and is environmentally friendly. Traditionally, lead was the best option for shielding against radiation. It is inexpensive and abundant, but it is toxic and highly-hazardous.

Polymer Tungsten has the same density and thickness as lead, therefore providing equivalent shielding properties. In addition, it is the leading substitute as it is more durable and better for the environment. It is nontoxic, dependable and meets US, EPA, OSHA, and RoHS standards. It keeps its form during use and can be used in many applications: such as X-ray equipment, CT scanning devices, tungsten poly syringe and tungsten poly collimator, to name a few.

Tungsten Polymer provides lead free, nontoxic engineered thermoplastics for x-ray and gamma ray shielding applications, helping device manufacturers meet industry and health standards while overcoming regulatory concerns.

There are three factors which determine the amount of radiation received from a source: 1) time of exposure; 2) distance from source; and 3) shielding. Based upon the application, we optimize shielding by designing the material density and wall thickness to deliver the level of shielding the customer requires at the optimal price point. Utilizing a composite of tungsten powder in a polymeric matrix, T&D lead free radiation shielding materials provide device manufacturers and material processors with a completely lead-free, injection-moldable thermoplastic solution to overcome all regulatory concerns and satisfy radiation shielding needs. Moreover, our engineered x-ray and gamma ray shielding compounds are price competitive with other lead-free shielding materials.

Poly-tungsten is more durable than other lead substitutes and offers equal or better radiation-shielding capabilities in electronic and electrical products. Because it is malleable, poly-tungsten offers increased design flexibility and the opportunity to create molded parts in lieu of multi-part assemblies.
