OCSiAl Group offers TPU modified with graphene nanotubes to prevent static electricity buildup and arc discharge for various industries with special operating conditions, when dry bulk materials are conveyed by compressed air through a nonconductive hose. This can prevent sparks that can damage electronic components, or even fire or explosion.
Meet Heavy-duty Operating Applications Demands
The nanotube-modified hoses perfectly meet the demands of heavy-duty operating applications, which frequently require a combination of ESD protection and high abrasion resistance and durability.

Based on their excellent performance, these industrial TPU hoses can be widely used in pneumatic and aspiration systems for pumping or transporting materials with high abrasive properties, including abrasive powders, sawdust, chopped paper, construction waste, petroleum products, and crushed or granular materials.
“
Replacement of a standard compound with TPU modified with graphene nanotubes results in stable, homogeneous conductivity of the final hoses, without compromising their strength or flexibility. By adding only 0.4–0.5 wt% of graphene nanotubes, our client was able to obtain thermoplastic polyurethane with resistance of the order of 106 ohm/sq, allowing the hoses to meet the typical requirements of industrial norms related to electrostatic risks,” said Christian Maus, development and support leader for thermoplastics, OCSiAl Group.
“
Additionally, graphene nanotubes’ low working dosages make it possible to maintain the abrasion and chemical resistance, flexibility, and non-marking properties of TPU,” added Maus.
