Polymer Tungsten Sheet Description
Polymer Tungsten, also known as resin tungsten alloy or tungsten plastic, is a composite material made by combining tungsten alloy particles with various resin materials in different proportions. The tungsten alloy typically makes up 60% of the product's volume, while accounting for over 96% of its weight. The resins used in this composite can include polypropylene, polybutylene, polyurethane, and thermoplastic materials, among others.
Key Features of Polymer Tungsten:
Polymer Tungsten combines the high density, small volume, strong radiation shielding properties, and non-toxicity of tungsten alloys with the easy processing, cost-effectiveness, corrosion resistance, and good ductility of resin products. These superior characteristics make Polymer Tungsten an ideal material for applications in industries such as medical and fisheries.
Polymer Tungsten is particularly known for its excellent radiation shielding capabilities. With over 60% tungsten content, Polymer Tungsten offers a much higher radiation absorption rate compared to lead, making it an excellent choice for shielding components. For the same volume, Polymer Tungsten shielding absorbs one-third more radiation than lead-based materials.

Precautions
Although Polymer Tungsten is non-toxic and environmentally friendly, since the final products made from this material may be accessible to children, it is important to remind that children should not ingest it. After using toys or products made from Polymer Tungsten, it is recommended to wash hands thoroughly, and ideally, these products should be used under the supervision of an adult to avoid accidents. Parents are also advised to keep tungsten putty or tungsten resin away from food to prevent accidental ingestion. When cutting tungsten putty or tungsten resin with a knife or scissors, children should always be accompanied by an adult to prevent accidents.
