Overview

Product Introduction

Flextein® S51G is a 5.1 W/m∙K ultra soft thermal interface gap filler with great thermal performance and high compliance. The material yields extremely soft characteristics while maintaining elasticity and conformability. The inherent natural tack on both sides assists in application and allows the product to effectively fill air gaps, enhancing the overall thermal performance. It is ideal for use to fill gaps between high-power, heat-generating components and related heat sinks, boards or chassis. Flextein® S51G is naturally tacky on both sides and requires only a light pressure during assembly to secure components without adhesive. The thickness of the product can be customized in the range of 0.5-10.0mm according to the needs of customers, and one-sided adhesive can also be selected for ease of use.
