LeeP™ is Lee Spring’s response to increased requests for springs that combine the strength of metal with the special attributes of high performance engineered thermoplastics. After years of extensive engineering design and materials research, Lee Spring’s technical team has developed this unique compression spring offering.
LeeP™ springs are fabricated in distinctive formulations of Ultem* PEI resin, the material of choice for meeting LeeP’s specified criteria. LeeP Plastic Composite Springs are stocked in a variety of standard sizes, each available in a “rainbow” of strengths formulated from different Ultem* resins. The six increasing strengths are easily identifiable by distinct colors: Red, Orange, Yellow, Green, Blue and Violet. For other sizes, resins, or colors, Lee Spring has the advanced technology to provide Custom LeeP™ Compression Springs to meet the most exacting specifications.
