In 2025, more than 60% of OEMs reported overheating failures in high‑density power modules, leading to warranty claims that average $12,500 per incident. The root causes are often simple:
- High material cost – Standard silicone rubbers lack thermal pathways, forcing designers to add bulky metal heat sinks.
- Low thermal conductivity – Typical silicone (<0.2 W/m·K) cannot keep pace with modern 5 V/3 A power electronics.
- Slow delivery – Overseas suppliers average 45‑60 days lead time, jeopardizing launch schedules.
- Inconsistent quality – Batch‑to‑batch variation leads to unpredictable performance and costly re‑testing.
- Regulatory hurdles – Missing CE, RoHS or ISO certifications stalls market entry in Europe and North America.
Imagine a new electric‑vehicle inverter that fails after 3 months because the silicone seal cannot spread heat quickly enough. The result? A recall, brand damage, and a loss of $1.2 million in projected revenue.
Thermally Conductive Silicone Rubber – Your Competitive Edge
Our thermally conductive silicone rubber (TCSR) combines the flexibility of silicone with a thermal conductivity of 1.8 W/m·K – up to nine times higher than standard grades. Below are the core advantages that address every pain point above.
- High‑Performance Heat Transfer – Enables compact designs, eliminating oversized metal heat sinks.
- OEM/ODM Design Flexibility – Custom durometer (10‑80 ShA), colors, and dimensions for any application.
- Rapid Delivery – 7‑10 day lead time from order to shipment, thanks to our in‑house 55‑machine liquid silicone line.
- Full Compliance – CE, RoHS, ISO 9001, FDA, and UL certifications included.
- Cost‑Effective – Our pricing model averages 15 % lower than European competitors without sacrificing quality.

Application Scenarios & Case Studies
Below are three real‑world deployments that illustrate ROI and performance gains.
- Electric‑Vehicle Power Inverter – Replaced a 2 mm thick metal heat sink with a 1 mm TCSR gasket, cutting module thickness by 45 % and reducing thermal resistance from 0.85 °C/W to 0.32 °C/W. Result: 18 % increase in continuous power rating.
- Medical Imaging Probe – Integrated TCSR overmold to protect sensitive ASICs. The probe passed ISO 10993 biocompatibility testing and achieved a 30 % faster sterilization cycle.
- Industrial IoT Gateway – Switched from standard silicone to TCSR, eliminating a fan‑based cooling system. Energy consumption dropped by 22 W per unit, saving $4,500 annually for a 5,000‑unit deployment.

Frequently Asked Questions
What is the typical thermal conductivity range for your silicone rubber?
1.5 – 2.2 W/m·K depending on filler loading (aluminum oxide, boron nitride). Our standard grade is 1.8 W/m·K, which meets most automotive and medical specifications.
Can you provide OEM/ODM customization for durometer and dimensions?
Yes. Our engineering team works with you from CAD to pilot run. We can produce custom durometer from 10 ShA to 80 ShA, color matching, and thickness from 0.5 mm up to 10 mm.
What certifications do you hold for export to the EU and North America?
We hold CE, RoHS, REACH, ISO 9001, ISO 13485 (medical), FCC, UL‑94V‑0, and FDA‑GRAS certifications. All certificates are available on request.
How do you ensure consistent thermal performance across large batches?
We use in‑line rheology monitoring and real‑time thermal conductivity sensors on each production line (see MDPI study [1]). Statistical Process Control (SPC) keeps variance < 2 %.
What are the payment terms and shipping options?
Standard terms: 30 % T/T upfront, 70 % on delivery. For trusted partners we accept L/C or Net‑30. Shipping via DHL, FedEx, or sea‑freight with full customs documentation.
Do you offer a risk‑free sample program?
Absolutely. We ship up to 5 kg of sample material (any grade) at no charge. If it does not meet your specifications, you keep it for free.
