TUBALL™ graphene nanotubes in the form of TUBALL™ MATRIX 822 and TUBALL™ MATRIX 808 are a versatile conductive additive based on polyol ester carrier. They have been specifically designed to provide superior electrical conductivity to thermoplastic materials, while retaining mechanical properties and keeping the MFI level of the glass fiber filled compound.
TUBALL™ MATRIX 822 incorporates in 2 steps and allows to produce masterbatches based on PA. Resulting masterbatches can be used for compounding in filled polymers or in combination with other conductive fillers to reduce their content and gain better mechanical properties and fluidity.
TUBALL™ MATRIX 808 has a smaller graphene nanotubes content and can be incorporated just in one step – direct compounding.
In contrast to conventional additives, TUBALL™ graphene nanotubes used at an ultralow working dosage bring additional value by preserving good impact strength and a high MFI level that makes it possible to produce complex injection molded parts. This is particularly hard to achieve in fiberglass-filled compounds using multi wall carbon nanotubes or carbon black.
