Nanovip All things Nanotechnology – Nano Is The Futiure
Brisbane, Australia-based nanotech specialist TenasiTech Pty Ltd has developed a nano-composite thermoplastic polyurethane system for use in seals which, it says, can increase the operating time of pumps and lower costs.
In tests, the nano-composites showed improvements in mechanical strength, creep resistance, compressive set and barrier properties. Creep resistance improvements were up by 67%, and compression set gains up by 45%. The nano-polyurethanes also performed significantly better after exposure to elevated temperatures for extended periods.
“The performance gains from our nano-additives are directly relevant to seals, giving their users the potential of longer mean time between failure and the possibility of pushing operating temperature ratings further for polyurethanes, which is a historical weakness for this class of polymer,” said managing director Richard Marshall.
The nanotechnology involves dispersing nanofillers into the host polymer’s chemistry. It originates from research at the University of Queensland and a number of patent applications are in progress globally. According to TenasiTech, it can be produced on an industrial scale.
“We have partners in the northern hemisphere for applications other than seals, but we are now actively seeking a partner to develop product in this exciting market,” said Marshall.
