LEN120 Non-Silicone Phase Change Thermal Grease

Thin Bond Line, Effective Surface Wetting, Reliable Thermal Contact

LEN120 is a non-silicone phase change thermal grease designed to improve heat transfer between electronic components and heat sinks. With a phase change temperature of ≥45°C, the material softens as it reaches its transition temperature, improving surface conformity and wetting to help reduce contact thermal resistance.

Its silicone-free formulation eliminates silicone oil leakage associated with silicone-based thermal compounds. Supporting a bond line thickness (BLT) of ≤10 μm, LEN120 provides a thin thermal interface for applications requiring close contact between mating surfaces.

This phase change thermal interface material (TIM) can be applied by screen printing, manual application, or automatic dispensing. Adjustable viscosity options support different application methods and production requirements.

Key Features and Benefits

Non-silicone formulation: Suitable for applications where silicone oil migration or contamination is a concern.

Phase change behavior: Improves conformity to mating surfaces and helps fill microscopic surface irregularities.

Low thermal impedance: Helps reduce resistance to heat flow across the thermal interface.

Thin bond line: Supports a BLT of ≤10 μm for closely fitted thermal assemblies.

Reliable stability: Designed to maintain consistent thermal contact in electronic applications.

Typical Applications

Electronic Components and LED Lighting

Thermal interfaces between ICs, CPUs, GPUs, or LED assemblies and heat sinks, helping transfer heat from the component to the cooling assembly.

Power Electronics

Thermal management for power modules and power semiconductors requiring effective heat transfer across closely fitted interfaces.

Automotive Electronics

Thermal interface applications in battery management systems (BMS) and engine control units (ECUs).

Networking and Telecommunications

Thermal management for heat-generating components in routers, base station equipment, and related communication systems.

Application and Processing

LEN120 thermal paste supports both manual assembly and automated production. Choose screen printing for patterned application, manual application for flexible assembly workflows, or automatic dispensing for controlled material placement.
