Discover nowEfficient thermal management for demanding electronics with KERAFOL® Softtherm® Gap Pads – your partner: alfatec.
As electronic components become smaller and more powerful, thermal management becomes increasingly critical. Without effective heat dissipation, overheating and system failure are real risks.
Thermal Interface Materials (TIMs) address this challenge by reliably transferring heat from the source (e.g., chip) to the sink (e.g., heatsink). alfatec offers high-performance, flexible, and cost-effective solutions with KERAFOL® Softtherm® Gap Pads.
Softtherm® Gap Pads are highly thermally conductive and electrically insulating TIMs. Made from flexible elastomers based on silicone or polyurethane, their softness and compressibility allow them to bridge large gaps and component tolerances between heat sources and sinks. They eliminate air gaps that hinder heat flow, ensuring efficient thermal transfer and extending the life of your electronics.
KERAFOL®, a leading manufacturer in this field, offers a wide range of Softtherm® Gap Pads, distributed by alfatec.
