Tungsten putty is a novel tungsten product made by bonding tungsten powder with a high-molecular polymer. Unlike typical tungsten products, it differs significantly in both shape and physicochemical properties. It is neither in the form of tungsten oxide powder nor the appearance of high-density tungsten alloys.
Physicochemical Properties
Tungsten Putty combines the characteristics of tungsten powder and high-molecular polymers. Its appearance resembles solid grease with a glossy, oily surface. Key features include high density, strong oxidation resistance, excellent plasticity, superior adhesion, good hydrophobicity, effective waterproofing, high-temperature resistance, corrosion resistance, and non-toxic, environmentally friendly properties.
Notably, Tungsten Putty softens as temperature increases. It comes in a variety of colors, such as black, brown, gray, and dark green. Its flexibility allows users to mold it into desired shapes based on preference.
Applications
Tungsten Putty is primarily used for making toy counterweights and fishing sinkers:
Toy Counterweights: These include balance weights for pinewood toy cars and model airplanes. Its high density and plasticity make it easy to adjust weight, while its non-toxic and eco-friendly nature ensures safety for children.
Fishing Sinkers: Tungsten Putty’s easily adjustable shape and ability to sink quickly in water make it ideal for this purpose.
Storage Recommendations
Tungsten Putty should be stored in a cool, dry, and sealed environment. Prolonged exposure to air or sunlight can cause dehydration and cracking. Additionally, the storage temperature should not be too high to facilitate packaging. It should be stored separately to prevent accidental ingestion by children and to maintain its purity.
