Automotive Thermal Grease Paste 1.0 W/mK Non-Curing for EV Battery Thermal Management

Automotive Thermal Grease Paste for EV Battery and Electronic Module Cooling

HN100 is a non-curing silicone-based thermal grease paste with 1.0 W/mK thermal conductivity, developed for automotive electronics and EV thermal management. Based on high-purity organic silicon material, it almost never solidifies and stays in a paste-like state for long-term use from -40°C to 180°C, providing durable heat dissipation for EV battery modules, electronic control units and power components.

Key Features

• Automotive Grade: Designed for automotive electronic components, EV battery modules, automotive refrigerators and power modules with demanding vibration and temperature cycles.
• Non-Curing Long-Term Stability: Almost never solidifies, keeping a paste-like state and stable thermal performance for long-term use from -40°C to 180°C.
• Excellent Electrical Insulation: Non-conductive organic silicon material protects sensitive electronic circuits.
• High Durability: Resistant to water, ozone and climate aging, with oil separation ≤0.3% and volatile matter ≤0.6% after 24 hours at 200°C.
• Low Impurities: High-purity formulation with impurity content tending towards zero for reliable long-term contact.
• Easy to Apply: Smooth paste spreads evenly and stays in place on vertical and vibrating surfaces.
• RoHS and REACH Compliant: Certificates available for global automotive supply chains.

Applications

• EV battery modules and battery management systems (BMS)
• Automotive electronic components and automotive refrigerators
• Power modules, transistors and thermistors
• CPU assemblies, temperature sensors and printer heads
• LED lamp heat dissipation interfaces and power templates

FAQ

Q1: What is HN100 thermal grease and what thermal conductivity does it provide?

A: HN100 is a single-component, non-curing thermally conductive silicone grease with a thermal conductivity of 1.0 ± 0.1 W/m·K. It maintains a paste-like 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. HN100 offers excellent electrical insulation with a breakdown voltage of 2450 V/mm at 0.20 mm thickness, and is non-toxic, odourless, non-corrosive and compliant with RoHS 2.0, with near-zero free radical content.

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

A: MOQ is 1 kg, supplied in 1 kg cans or 5 kg barrels (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.
