Company Advantages

Our thermal pads are developed using advanced polymer thermal material modification technology, enabling higher thermal conductivity, improved mechanical resilience, and tailored performance for demanding energy storage and EV applications.

  • Proprietary Polymer-Modification Technology — Our dry-process compounding enhances filler-matrix bonding, boosting thermal conductivity without sacrificing pad softness

  • Tailored Performance — We custom-engineer hardness, elasticity, and thermal properties for specific EV, energy-storage, or electronic applications. Products can be fine-tuned in thickness, geometry, adhesive, and formulation.

  • Durability & Stability — Polymer-engineered pads resist thermal cycling, mechanical vibration, and aging. They maintain conductivity and compliance after thousands of hours at temperature, ensuring device longevity.

Select thickness based on gap (0.2, 0.5, 1.0 mm common) and conductivity based on heat flux. Smartphones often use 0.8–5 W/m·K, high-power modules ≥6 W/m·K.

Yes — most silicone and non-silicone grades are dielectric. Always confirm breakdown voltage specs for your model.

Pads are clean, automatable, and consistent for fixed gaps. Pastes can be thinner and more conductive but are messy and less scalable.

Yes — thickness, hardness, adhesives, and conductivity can be customized. Samples available on request.
