This specialized Barium Sulfate for Plastics is a high-performance functional filler engineered to impart two vital and often synergistic properties to polymer composites: superior Flame Retardancy and effective Radiation Shielding. By incorporating this dense, chemically inert mineral into polymer matrices, compounders and engineers can create advanced materials that meet stringent safety and performance specifications across demanding sectors such as aerospace, automotive, construction, electronics, and medical equipment.
Flame Retardant Properties
As a flame retardant agent, barium sulfate operates through both physical and chemical mechanisms. Its high density and thermal stability (with a decomposition temperature exceeding 1580°C) contribute to a "filler effect" that dilutes flammable polymer content, reduces fuel load, and forms a stable insulating char layer during combustion. When exposed to fire, barium sulfate undergoes endothermic decomposition, absorbing heat and releasing non-combustible sulfur dioxide to suppress combustion. This makes it valuable in halogen-free flame-retardant systems for electrical connectors, circuit board substrates, and public transportation components.
Radiation Shielding Capabilities
As a radiation shielding agent, barium sulfate leverages the high atomic number of barium to effectively attenuate X-rays and gamma rays. When compounded into plastics, it provides a lightweight, moldable, and cost-effective alternative to traditional lead-based shielding. The uniform dispersion of fine barium sulfate particles creates a homogeneous barrier that scatters and absorbs high-energy photons, making it ideal for medical protective equipment, radiation therapy room shielding, X-ray analyzer enclosures, and nuclear facility components. Our product features controlled particle size and surface treatment for excellent dispersion and consistent shielding properties.
