LEN200 Non-Silicone Phase Change Thermal Grease

2.0 W/m·K Thermal Conductivity for Thin Thermal Interfaces

LEN200 is a silicone-free thermal grease formulated for heat transfer between electronic components and cooling assemblies. Combining a thermal conductivity of 2.0 ± 0.2 W/m·K with a bond line thickness (BLT) of ≤10 μm, it supports thermal interface designs where both material conductivity and interface thickness matter.

At its phase transition temperature of ≥45°C, LEN200 softens to conform to the mating surfaces. This behavior promotes surface wetting and helps fill microscopic gaps, reducing contact thermal resistance between the heat source and heat sink.

The non-silicone formulation avoids silicone oil leakage and associated contamination concerns. With adjustable viscosity options and support for multiple application methods, LEN200 fits a range of electronic assembly processes.

Performance and Processing Advantages

2.0 ± 0.2 W/m·K thermal conductivity: Facilitates heat transfer through the interface material.

Phase change surface conformity: Helps accommodate microscopic surface irregularities as the material softens.

Thin bond line capability: Supports interface thicknesses of ≤10 μm in closely fitted assemblies.

0.026 °C·in²/W thermal impedance: Provides low resistance to heat flow across the thermal interface.

Silicone-free composition: Addresses silicone oil migration concerns in sensitive electronic assemblies.

Application flexibility: Supports screen printing, manual application, and automatic dispensing, with viscosity options to match processing requirements.

Thermal Management Applications

LEN200 phase change thermal interface material (TIM) is designed for use between heat-generating components and heat dissipation hardware across several application areas:

LED lighting: Thermal contact between LED assemblies and associated cooling structures.

Integration into Your Assembly Process

Apply LEN200 thermal paste using screen printing, manual spreading, or automated dispensing according to the interface geometry and production workflow. Adjustable viscosity options provide flexibility when selecting material delivery and deposition methods.
