Plastic springs offer a number of beneficial properties and can be used in applications that require non-magnetic, non corrosive springs. Due to high demand, Lee Spring has developed the LeeP™ plastic composite springs range.
The unique LeeP springs combine the strength of metal with the special attributes of high performing engineered thermoplastics, and were developed by Lee Spring after years of extensive engineering design and materials research to create a truly unique compression spring offering.
LeeP plastic springs are inert and non-magnetic with a high strength to weight ratio, excellent corrosion resistance, low flammability and toxicity and offer stability at elevated temperatures. Lee Spring’s LeeP™ plastic springs are available in varying strengths and, to help when specifying and ordering, are colour coded: Red, Orange, Yellow, Green, Blue and Violet. LeeP Springs are also recyclable.
Plastic LeeP springs offer numerous advantages. For example, LeeP springs offer high strength to weight ratios, which help to optimise performance whilst reducing mass and providing high corrosion resistance, as well as being compatible with many chemicals including strong acids, weak bases, aromatics, and ketones.
LeeP springs are made from non-magnetic materials that do not interfere with imaging and other Ferro-sensitive technologies. They offer low flammability and toxicity to ensure environmental safety and are recyclable, complying with most Global regulations including RoHS and REACH.
LeeP Springs are designed to meet a wide range of spring applications. Because of the non-corrosive, non-metallic and high strength properties offered by plastic LeeP springs, some applications they are particularly well suited to include aerospace products, marine products, electronics and electronic equipment, water purification systems, chemical environments, communication devices, imaging and X-Ray equipment and cosmetics packaging equipment.
For applications requiring more specialised plastic springs, Lee Spring has the advanced technology to provide custom LeeP Compression Springs to meet the most exacting specifications.
