Zele, Belgium - Diamond Spring Company (DSC), a specialist in sleep comfort products, has developed a new fully-polyurethane eco-friendly spring, the company said 2 Sep.
Octaspring, named so because of its eight-sided honeycomb-like structure, is designed for use in mattress cores, pillows, seating and furniture as well as in the car industry, DSC said, adding that the Octaspring created some interest at the latest Interzum trade fair in Cologne, Germany.
"Our R&D team has been searching for the perfect PU spring for years," said DSC director, Willy Poppe, commenting that as pressures on health and the environment continued to rise DSC decided to create a full PU spring, a product which was previously considered "technically impossible due to its weak structural support."
"We have, however, succeeded in developing a technological concept as well as the associated production tools to produce a spring that consists entirely of PU material," Poppe added.
According to DSC, the Octaspring is unique in ecological terms. Using the Octaspring as a suspension system, the statement said, can save 30 - 40 percent on raw materials in comparison with current PU foam fillings, "with better results." Potentially this could mean savings of hundreds of thousands of tons of CO2 emissions on production of PU foam, DSC pointed out.
Advantages of the Octaspring include the ability to produce a wide range of spring resistances and heights, for example mounting several rows of springs of varying resistance on top of each other to obtain the optimal suspension and capacity for a mattress core. The construction also offers perfect air permeability and complete discharge of moist air. The Octaspring was also awarded a maximum score for comfort and durability in a test conducted by the LAG research lab in Germany, the statement added.
Patents for the Octaspring technology are currently pending worldwide and DCS is negotiating its first deliveries of test samples to major European mattress brands, the company said. (RD)
