Environmentally friendly Powerdown shock absorber development

Heavy-duty equipment specialist, Powerdown, has taken a step further in developing an environmentally friendly shock absorber solution.

Collaborating with Re-Oil, a local Newcastle oil and lubrication company, Powerdown were instrumental in the development of the tailored high-performance shock absorber fluid made from sugar cane. The base fluid selected for this application not only originates from a renewable plant-based resource but is also biodegradable. This makes BioShock Ultra, according to Powerdown, the logical choice for an environmentally conscious user, who will not compromise on product performance.

Key performance features of this new fluid include a superior ability to distribute heat, which facilitates high rates of heat dissipation within the fluid and a superior flash point compared to traditional shock absorber oils. The benefits of these features allow for exceptional shock absorber performance and endurance with consistent high resistance to fade or loss of damping. These characteristics ensure high level wheel stability for positive road traction and braking.

Bench testing
To ensure that the new fluid would perform to Powerdown’s rigorous standards, a thermo-study was carried out at the Powerdown test facilities on a number of dynometers and data gathering test machinery to expose the fluid to the most conceivable parameters of stress and enduring resistance factors, including any physical break down of the fluid composition that may have revealed themselves when subjected to the ‘torture tests’ considered compulsory by Powerdown.

On highway testing
A six-month trial is currently underway, with the support of a well-known transport company on a pair of B-double tanker combinations.
During the six-month trial data and tyre wear will be monitored to evaluate the performance of the shock absorber technology in real world working conditions.

The Powerdown engineering team will be available to discuss new exciting product developments at the 2019 Brisbane Truck Show.

Biodegradability explained
The industrial jargon ‘readily biodegradable’ – according to Powerdown – means that a product is likely to reach biodegradation of up to 60 per cent in 28 days, and the 60 per cent level is reached within 10 days of reaching the 10 per cent mark (‘10‐day window’ criterion). In general, a ‘readily biodegradable’ material biodegrades more rapidly and more completely than an ‘inherently biodegradable’ material.
