- Performance
AOS 340 LR's exceptional performance can be attributed to its durability and resistance to pump-out. AOS 340 LR was uniquely engineered and tested under thermal cycling conditions in order to ensure stability. Due to the growing number of various applications in the thermal management industry, an increased demand for longer lasting products has proven essential. AOS 340 LR's resistance to pump-out provides excellent performance and product longevity.

- Ready-to-Use Products
- Labeling Claims
- Non-Hazardous
- Non-Reactive
- Major Applications
AOS 340 LR is designed to be applied where thermal coupling is required and where a device may need to be removed from the heat sink at a later time. Major applications include CPU/GPU, power semiconductors and LED's. It is also the most efficient and cost effective low bond line TIM 2 for use in any thermal management application.
- Benefits and Features
AOS 340 LR is non-silicone based, non-reactive, and non-abrasive with a soft, grease-like consistency with thixotropic behavior. It has excellent dielectric properties, lowest thermal resistance and superior durability (will not pump-out).
- Non-Silicone Advantages
Silicone-based compounds have an undesirable tendency to physically migrate and contaminate components nearby. This interferes with circuit operation long after hardware installation to cause unexpected, untimely and often inaccessible problems. The AOS Heat Sink Compound's no creep feature extends circuit life by protecting components longer and by eliminating premature failure of adjacent components caused by migrating silicone base fluid.
