OEM Custom 1.0 W/mK Thermal Grease Bulk Supply Thermal Paste for LED Driver EV Battery Cooling

HN100 is a single-component, non-curing thermally conductive silicone grease produced in our own plant and supplied as an OEM/ODM programme for brand owners, distributors and contract manufacturers. The standard formulation delivers 1.0 ± 0.1 W/m·K thermal conductivity, 2450 V/mm electrical insulation and stable performance from −50 °C to +200 °C. Colour, consistency, thermal conductivity grade, filling weight and packaging can be customised, and bulk quantities are produced with batch-level TDS and RoHS 2.0 documentation.

• OEM / ODM formulation: custom thermal conductivity grade, colour, viscosity and packaging under your brand
• Bulk supply: 1 kg, 5 kg and larger drums for production lines, distributors and private label programmes
• Thermal conductivity: 1.0 ± 0.1 W/m·K (ASTM D5470)
• Non-curing: maintains paste consistency indefinitely; no hardening or drying
• Electrical insulation: breakdown voltage 2450 V/mm at 0.20 mm (IEC 60243)
• Wide operating range: −50 °C to +200 °C; no powdering after 8 days at 200 °C
• Low oil separation and volatility: ≤ 0.3% and ≤ 0.6% at 200 °C / 24 h
• Compliance: RoHS 2.0, non-toxic, odourless and non-corrosive

• Performance grade: thermal conductivity tuned for your target application and cost structure
• Appearance: white, grey or custom colour to match your brand and inspection requirements
• Consistency: penetration and rheology adjusted for syringe, cartridge, pail or automated dispensing lines
• Packaging: syringes, cartridges, 1 kg and 5 kg drums, and bulk containers with your label and artwork
• Documentation: batch-level TDS, RoHS 2.0 declaration and OEM labelling support

HN100 is used across electronic, electrical and automotive assemblies with demanding thermal requirements:

• LED and lighting: LED driver boards, LED lighting fixtures, lamp modules and driver power supplies
• EV and automotive: EV battery thermal management, automotive electronics, car refrigerators and in-vehicle power modules
• Power conversion: regulated power supplies, voltage regulators, switching power supplies and power supply modules
• Power semiconductors: power transistors, thyristors, power modules and IGBT assemblies
• Microwave and RF: microwave devices, microwave communication systems, microwave transmission equipment and microwave power supplies
• Sensing and imaging: thermistors, temperature sensors, sensor housings, printer heads and thermal print bars
• Computing: CPU assemblies, GPU heat sinks, graphics cards, notebooks and gaming hardware
• General hardware: heat sinks, heat exchange strips, metal housings and chassis requiring an insulating thermal interface

All values are measured under standard conditions and are for reference only. Actual thermal performance may vary with application conditions, bond line thickness (BLT) and contact pressure. Custom grades are confirmed against the approved sample and specification.

1. Surface preparation: clean all contact surfaces with a solvent to remove grease, dust and oxidation; ensure surfaces are completely dry.
2. Application: apply by brushing, rolling, automatic dispensing or screen printing according to your line configuration.
3. Spreading: spread a thin, even layer with a razor blade, plastic spatula or dispensing program.
4. Thickness control: keep the bond line as thin as possible for maximum heat transfer; wipe excess from edges with a lint-free cloth.
5. Assembly: mount the heat sink or component immediately and torque fasteners to specification for a uniform bond line.

Q1: Can HN100 thermal grease be customised for OEM and ODM projects?
A: Yes. HN100 is offered as an OEM/ODM programme: thermal conductivity grade, colour, penetration and rheology, filling weight, syringe or drum packaging, labels and artwork can be customised, with batch-level TDS and RoHS 2.0 documentation supplied for each production lot.

Q2: What thermal performance does the standard HN100 formulation provide?
A: The standard HN100 grade delivers 1.0 ± 0.1 W/m·K thermal conductivity by ASTM D5470, specific gravity 1.85 ± 0.08 g/cm³, cone penetration 370 ± 20 and 2450 V/mm breakdown voltage at 0.20 mm thickness.

Q3: Is HN100 suitable for LED drivers, EV batteries and power supplies?
A: Yes. HN100 is used for LED driver boards and lighting fixtures, EV battery thermal management, automotive electronics, regulated and switching power supplies, power modules, microwave equipment, CPU and GPU heat sinks, temperature sensors and printer heads.

Q4: Does HN100 cure or dry out in long-term service?
A: No. HN100 is a single-component, non-curing silicone grease that keeps its paste consistency indefinitely. It shows no powdering after 8 days at 200 °C, no drying after 3 hours at 280 °C, with oil separation ≤ 0.3% and volatility ≤ 0.6% at 200 °C for 24 hours.

Q5: What packaging and supply options are available for bulk orders?
A: HN100 is supplied in 1 kg and 5 kg plastic drums as standard, with custom sizes, syringes, cartridges and bulk containers available on request. Shelf life is 12 months from the date of manufacture when stored unopened below 27 °C in a cool, dry, well-ventilated area.

• Packaging: 1 kg and 5 kg plastic drums as standard; syringes, cartridges and custom bulk containers on request
• Storage: keep containers tightly sealed in a cool, dry, well-ventilated area away from direct sunlight; recommended below 27 °C
• Shelf life: 12 months from date of manufacture when stored unopened and properly sealed
• Transportation: classified as non-dangerous goods; handle with care to prevent leakage
