ML6 Polyurethane for Research & Testing Applications
Meridian Laboratory’s ML6 polyurethane parts are used across research and testing applications like non-destructive testing, crash test sleds, and arctic ice core drilling equipment. From high-friction encoder wheels that measure precisely without slipping, to non-marking rollers that won’t scuff sensitive surfaces such as painted aircraft. ML6 polyurethane is trusted in labs and field sites alike. Each part is precision-molded and chemically bonded for lasting use in extreme cold or high-cycle environments without cracking, peeling, or losing performance.
Application & Uses
Common Applications & Uses for Molded Polyurethane in Research & Testing

Non-Marking & Precision Molded
ML6 polyurethane coated rollers and encoder wheels are used in non-destructive test equipment to inspect specific sections of aircraft while avoiding scratching the outside of the fuselage.
The ML6 Advantage
ML6 polyurethane encoder wheels feature high friction and precise total indicated runout (TIR) for consistent measurements during operation. They are non-marking, leaving no witness marks or color transfer.

High Bond Strength for Lasting Performance
ML6 molded cam followers are used in various test sleds to hold and transport vehicles and other test apparatuses used in crash testing analysis.
The ML6 Advantage
ML6 polyurethane is molded and bonded in one step to bearings and cam followers, providing strong bond strength and extended life through repeated use without delamination.
