A tungsten rubber sheet is a flexible composite material formed by uniformly dispersing tungsten powder into a polymer rubber matrix through hot pressing or calendering processes.
Tungsten rubber sheets are flexible shielding materials made by embedding fine tungsten powder into a high-polymer rubber base. The material is shaped via thermal compression or calendaring techniques. Its main feature lies in the combination of high radiation shielding performance and excellent flexibility, making it widely used in medical radiation protection, industrial radiographic testing, nuclear equipment, and aerospace applications. It serves as an environmentally friendly alternative to traditional lead-based shielding materials.
Comparison: Tungsten Rubber Sheet vs. Lead Rubber Sheet
Tungsten rubber sheets offer stronger shielding capability, greater flexibility, non-toxic and recyclable environmental friendliness, and longer service life, all while complying with environmental regulations such as RoHS.
| Performance Comparison | Tungsten Rubber Sheet | Lead Rubber Sheet |
| Shielding Ability | Strong (tunable density) | Strong (but fixed density) |
| Flexibility | Excellent (easier to bend) | Average |
| Environmental Safety | Non-toxic, recyclable | Contains lead, pollution risk |
| Odor | Odorless | Slight metallic/lead odor |
| Service Life | More resistant to aging and oxidation | Prone to aging and cracking |
| Regulatory Compliance | Complies with RoHS, REACH, etc. | Restricted or being phased out |
