Lee Spring's 2010 stock and custom catalog introduces two innovative product lines featuring technically advanced...
Lee Spring introduces LeeP™ plastic composite springs, a revolutionary breakthrough in spring technology.
LeeP is Lee Spring’s answer to increased customer requests for springs that combine the strength of metal with the special attributes of high performing engineered thermoplastics. After years of extensive engineering design and materials research by their expert technical team, Lee Spring developed these unique compression springs.
LeeP springs are fabricated in distinctive formulations of Ultem PEI resins. “We specifically selected Ultem resin as the material of choice for LeeP,” says Lee Spring president Al Mangels. “It meets or exceeds the criteria we set forth for developing this line. You might call Ultem resin the ‘spring steel’ of plastics.” Ultem resin is produced by SABIC Innovative Plastics, a leader in engineered thermoplastic material solutions.
LeeP plastic composite springs are stocked in a range of standard sizes, each available in a variety of strengths formulated from different Ultem resins. The six increasing strengths are easily identifiable by distinct colors: red, orange, yellow, green, blue and violet, with violet being the strongest. In addition to their initial LeeP stock compression spring offering, Lee Spring has developed the advanced technology to provide custom LeeP springs to meet customers’ most exacting requirements.
