Plastic composite compression springs – a complete package

By offering non-magnetic, non-corrosive and chemically inert properties in a lightweight package, LeeP springs are often a complete solution for applications in areas of medical device manufacturing, pharmaceutical equipment, aerospace and lightweight e.g. portable instrumentation.

The LeeP range combines the strength of metal springs with the attributes of high performing engineered thermoplastics – in this case Ultem PEI (polyetherimide) resin which has excellent thermal stability and electrical insulation properties, while being non-contaminating. They have low flammability and are recyclable in compliance with global regulations including RoHS and REACH. LeeP Plastic Composite Springs are stocked in a variety of standard sizes, each available in strengths formulated from different Ultem resins. 

These plastic compression springs offer high strength to weight ratios that optimize performance while reducing mass; they have excellent stability of physical and mechanical properties at elevated temperatures up to 170°C; high corrosion resistance and are generally compatible with many chemicals including strong acids, weak bases, aromatics, and ketones.
