Anti-static agent for electrically conductive EPDM
TUBALL graphene nanotubes are applied in EPDM rubber as a high-performance additive for anti-static, static dissipative and conductive applications. TUBALL provides rubber compounds with the target volume resistivity level, while improving mechanical properties by up to 70% and retaining color.
Graphene nanotubes (or single wall carbon nanotubes) are a very strong, conductive and flexible material, with a record length-to-diameter ratio. This unique combination of properties allows graphene nanotubes to create reinforcing and conductive network inside rubbers even at extremely low loadings. This ability gives nanotubes an undeniable advantage over the use of other additives, such as carbon black, multi wall carbon nanotubes, and polymer-based anti-static agents, which lead to a number of negative effect on the material’s mechanical properties, especially in elasticity and softness.
Improvement of tear strength and tensile parameters evaluation in 3 viscosity types of EPDM
To allow manufacturers to easily apply graphene nanotubes at the final mixing stage, OCSiAl has developed a ready-to-use concentrate, TUBALL MATRIX, containing pre-dispersed nanotubes and a blend of polymer and paraffin oil. It is suitable for EPDM and other polymers that are relatively compatible with butadiene copolymers.
TUBALL MATRIX features:
- For anti-static, static dissipative and conductive applications
- Improved mechanical properties, such as tensile modulus and tear strength increased by up to 70%
- Retain colors, no carbon release to surface
- Permanent, stable level of electrical conductivity
- Carrier compatible with a wide range of Mooney grade formulations and fillers
- Maintained rheology, softness and elastic properties
- Standard processing and mixing equipment
Colored anti-static compounds with graphene nanotubes are in high demand in electronics and cables, conveyer manufacturing and the printing industry, in a wide range of products where stable electrical conductive properties are required in combination with a long service life and color options.
