Graphene Nanotubes Prevent Static Electricity Buildup in TPU Hoses

In various industries with special operating conditions, when dry bulk materials are conveyed by compressed air through a nonconductive hose, there is a risk of the accumulation of electrical charge due to friction. This can lead to sparks, resulting in damage to electronic components, or even fire or explosion. To prevent static electricity buildup and arc discharge, conductive material enhanced with metal wire is used as the key component for the manufacture of this type of conveying hose. The use of traditional conductive agents like carbon black requires high concentrations, which results in detrimental effects on the mechanical properties of the final product, including reduced flexibility.

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 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.
