Lee Spring introduces LeeP Plastic Composite Springs

By Patrick Curran | January 13, 2010

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. It meets or exceeds the criteria we set forth for developing this line. You might call Ultem resin the ‘spring steel’ of plastics,” states Lee Spring President Al Mangels. Ultem resin is produced by SABIC Innovative Plastics, a leader in engineered thermoplastic material solutions.

LeeP™ Plastic Composite Springs

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, 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.

LeeP Springs offer many advantages including:

• Unique patent pending designs to maximize spring rates and cycle life, while minimizing solid height
• High strength to weight ratios that optimize performance while reducing mass
• Excellent stability of physical and mechanical properties at elevated temperatures up to 340° F
• High corrosion resistance and generally compatible with many chemicals including strong acids, weak bases, aromatics, and ketones
• Non-magnetic material does not interfere with imaging and other Ferro-sensitive technologies
• Dielectric insulating material suitable for non-conductive applications
• Inert non-contaminating plastic composite protects product purity
• Low flammability and toxicity ensuring environmental safety
• Recyclable and compliant with most Global regulations including RoHS and REACH
