LeeP™ Plastic Composite Series Compression Springs

  • Non-Magnetic Material
  • High Corrosion Resistance
  • High Strength to Weight Ratio

Lee Spring LL 075 100 U40G is a plastic composite compression spring from the LeeP™ Plastic Composite Series series, specifically engineered for unique applications with specialzed characteristic requirements like non-magnetic and high strength to weight ratios. This spring features an 0.72-inch outside diameter (18.29 mm) with a 0.75-inch hole diameter (19.05 mm) and extends to a free length of 1 inch (25.4 mm), making it ideal for stamping and die applications. Made from Ultem with a 0.062-inch wire diameter (1.57 mm), the spring delivers a spring rate of 12.04 lb/inch (2.109 N/mm) through its 2.16 active coils out of 4.16 total coils for predictable deflection behavior. The spring compresses to a solid height of 0.259 inch (6.58 mm) while supporting a maximum load of 8.941 lb (39.77 N) at full compression. The spring has Tapered flat type ends.

About the LeeP™ Plastic Composite Spring Series

LeeP™ Plastic Composite Springs are an innovative compression spring designed to have properties unavailable in a metal spring. The LeeP™ Plastic Composite Spring Series offers a wide range of sizes and strength combinations to meet unique application requirements such as high corrosion resistance, excellent strength to weight ratio and designed to perform under load with minimal side thrust.Made of a unique formulation using Ultem® PEI resins, the LeeP™ Series is designed for optimal performance in a wide range of applications.

LeeP™ Plastic Compression Springs offer many advantages including:

  • Unique patented design to maximize spring rates and cycle life, while minimizing solid height (US Patent No. 8,939,438 B2).
  • High strength to weight ratios that optimize performance while reducing mass.
  • Excellent stability of physical and mechanical properties at temperatures up to 340°F (171° C).
  • 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.
  • Low flammability and toxicity ensuring environmental safety.
  • Recyclable and compliant with most Global regulations including RoHS and REACH.

LeeP™ Plastic Composite Series Compression Springs have useful applications in various industries, including:

  • Medical devices
  • Firearms
  • Pharmaceutical delivery devices
  • Lighting and electrical control
