Insulating LED Lamp Thermal Grease Paste HN200 White for Driver Power Supply Heat Sink Cooling

LED Lamp Thermal Grease Paste HN200 for Driver and Power Supply Cooling

HN200 is a white silicone-based thermal grease paste developed for LED lighting and power electronics. It transfers heat efficiently from LED chips, lamp drivers and power supply components to the heat sink, keeping junction temperatures low and extending LED service life.

Key Features

• LED Lighting Application: Formulated for LED lamp modules, LED drivers and switching power supplies with continuous heat load.
• High Thermal Conductivity: 2.0 W/mK efficiently moves heat from LED chips and driver components to the heat sink.
• High Breakdown Voltage: 2450V breakdown voltage provides electrical insulation around live LED driver circuits.
• Easy to Apply: Smooth 76000 cP paste spreads evenly between LED module and heat sink, minimizing air gaps.
• Wide Temperature Range: Stable performance from -50°C to 200°C for indoor and outdoor lighting.
• Long-Term Stability: Oil separation ≤0.3% and volatile matter ≤0.6% after 24 hours at 200°C keep thermal performance over the lamp lifetime.
• RoHS and REACH Compliant: Safe for global lighting product certification.

Applications

• Between LED chip module and lamp heat sink
• LED driver and power supply component cooling
• Outdoor and high-power LED luminaires
• General heat sink assembly for lighting electronics

FAQ

Q1: What is HN200 thermal grease and what thermal conductivity does it provide?

A: HN200 is a single-component, non-curing high thermal conductive silicone grease with a thermal conductivity of 2.05 ± 0.1 W/m·K and thermal resistance of 0.82 °C·cm²/W at 25 PSI. It maintains paste consistency from −50 °C to +200 °C for heat transfer between heat-generating components and heat sinks.

Q2: Is this thermal grease electrically insulating, non-corrosive and RoHS compliant?

A: Yes. HN200 offers excellent electrical insulation with a breakdown voltage of 2450 V/mm at 0.20 mm thickness, and is non-toxic, odourless, non-corrosive with near-zero ionisation, and compliant with RoHS 2.0.

Q3: What are the MOQ, packaging, application methods and shelf life?

A: MOQ is 1 kg, supplied in 1 kg or 5 kg plastic drums (custom sizes on request). It applies by brushing, rolling, automatic dispensing or screen printing. Shelf life is 12 months when stored below 27 °C; stir before use if a small amount of oil separates.
