Product Description
High Thermal Conductive Silicone Potting Compound Manufacturer | RTV-2 Encapsulant for EV & ESS
Product Description for silicone potting compound:

We are a leading China-based manufacturer supplying high-performance RTV-2 addition-cure silicone potting compounds. Specially engineered for power electronics in Renewable Energy, Photovoltaic (PV) inverters, Energy Storage Systems (ESS), and EV Charging Infrastructure, our encapsulation silicones deliver superior thermal management, high-voltage electrical insulation, and extreme weather protection.

Key Features & Value Proposition for silicone potting compound:
  1. Superior Thermal Management: Prevents thermal runaway and hot-spot degradation in high-power density modules.
  2. Addition-Cure RTV Silicone System: 1:1 mix ratio by weight, deep section curing without releasing heat or corrosive by-products.
  3. Flame Retardancy & Safety: UL 94 V-0 certified, ensuring maximum fire safety for high-voltage electronics.
  4. Extreme Environmental Endurance: Maintains permanent rubber elasticity across -50℃-+250℃, resistant to thermal shock, humidity, and vibration.

Application Scenarios for silicone potting compound:
  1. Energy Storage Systems (ESS): Liquid/air-cooled battery packs, Battery Management Systems (BMS), and Power Conversion Systems (PCS).
  2. EV & Automotive: DC-DC converters, EV fast charging piles/stacks, automotive ignition modules, and HID lighting power supplies.
  3. Solar Photovoltaics: PV junction boxes, micro-inverters, and high-voltage transformers.

Technical Specifications for silicone potting compound:
Property Value
Thermal Conductivity (W/m·K) 0.76- 3.0W/m.k
Viscosity (Mixed, mPa·s) 2,000-11,000 mPa
Dielectric Strength 25-30kV/mm
Flame Retardant Rating UL 94 V-0
Hardness (Shore A) 35 -50(Shore A)
Packaging & Usage Guidelines for silicone potting compound:
  1. Packaging: 50kg/set (25 kg Part A) + 25 kg Part B). Bulk industrial packaging available for automatic dispensing systems.
  2. Usage & Precautions: Accurately weigh Part A and B at a 1:1 ratio. Stir Part A thoroughly before mixing to ensure settled thermal fillers are evenly dispersed. Vacuum de-airing (5–10 minutes) is strongly recommended to eliminate trapped air bubbles. Avoid contact with organotin, sulfur, amines, or flux residues to prevent catalyst poisoning (inhibition of curing).
  3. Storage: Store in a cool, dry place. Shelf life is 6 months
Q&A for silicone potting compound

Q: Can your factory provide custom thermal conductivity or viscosity formulations for our OEM projects?

A: Yes. As a direct manufacturer, our R&D engineering team provides custom formula debugging, adjusting viscosity, curing speed, or hardness to fit your precise automated dispensing process and thermal design requirements.
