Anti-static agent for conductive polyethylene rotomolded parts with preserved mechanical properties and light colors

TUBALL™ graphene nanotubes (single wall carbon nanotubes) provide superior electrical conductivity to polyethylene rotomolded parts. Graphene nanotubes’ unique morphology allows them to create a dense conductive network inside polyethylene rotomolded parts at ultralow loading rates—starting from just 0.01 wt.% in the total compound. This unprecedentedly low concentration has minimal impact on the mechanical properties or the original color of the material.

TUBALL™ graphene nanotubes are applied via easy-to-use TUBALL™ MATRIX, which is a line of additives based on polymer carriers and pre-dispersed TUBALL™ graphene nanotubes, or TUBALL™ COAT_E suspensions.

Choose the TUBALL™-based product based on your requirements:

Concentrate carrier	Water + anionic surfactant	Alkylolammonium  salt	Polyethylene wax
Form	Suspension	Paste	Pellets
Conductive properties	Anti-static / conductive 105–109 Ω/sq	Anti-static 107–108 Ω/sq	Anti-static 106–107 Ω/sq
Working  dosages*	0.25–2.50 wt.%	0.5 wt.%	0.7–1.0 wt.%

*Values may vary depending on the formulation, processing, and products, and are given as a typical reference. 

TUBALL™ anti-static additive for polyethylene rotomolded parts demonstrates the following benefits:  

• Permanent, stable anti-static properties without “hot spots”
• Maintained or even increased mechanical properties
• Possibility of color solutions*
• Stable performance reducing the number of out-of-spec parts

*Depending on the formulation, processing, and products.

Maintained mechanical properties

In contrast to conventional additives, graphene nanotubes make it possible to preserve the mechanical properties and light colors, and have a minimal impact on the viscosity and density, of the host material.
