As automotive devices and batteries evolve, thermal management and durability are becoming increasingly important. The SEMICOSIL® series delivers excellent heat dissipation and can withstand harsh environments.

As automotive devices and batteries evolve, thermal management and durability are becoming increasingly important. The SEMICOSIL® series delivers excellent heat dissipation and can withstand harsh environments.

Feature01

High thermal conductivity and low viscosity

A broad product lineup is available with thermal conductivity ranging from 2W/m·K to 8W/m·K. Its low viscosity enables it to accommodate surface irregularities, reducing interface thermal resistance. By reliably filling gaps, heat from automotive batteries and electronic devices is effectively dissipated, delivering superior thermal performance.

Feature02

Flexible performance across wide temperatures

Utilizing the unique properties of silicone, it maintains stable physical characteristics across a wide temperature range from -50°C to +180°C. Even after curing, it retains flexibility and adjusts to the shape of the substrate, helping to relieve stress.

Feature03

Superior resistance to pump-out and bleed-out

As a two-component, room-temperature curing material, it prevents issues such as pump-out or bleed-out caused by thermal expansion and contraction of the substrate. Its thixotropic properties allow precise control of the intended shape and application thickness.

Usage example01

EV/HEV batteries

Highly flowable thermal gap fillers fill the gaps between heat sinks and modules, providing excellent heat dissipation. These advantages have driven wider use in EV/HEV battery cells. Sales are also expanding for electro-device applications that demand high thermal performance due to the miniaturization of electronic components.

Product Q&A

QHow does it differ from thermal pads?

A Automated dispensing with equipment helps improve productivity. It also makes it easy to adjust application thickness and ensures reliable heat dissipation by filling even the finest surface irregularities.
