## **Tflex[TM] HD300 Series Thermal Gap Filler** 

## **PRODUCT DESCRIPTION** 

Laird Tflex[TM] HD300 is a 2.7 W/mK gap filler material in Laird’s high deflection line of products.  Tflex HD300 is an excellent choice when wide manufacturing tolerances occur as variable gaps can be filled with Tflex HD300 while generating minimal board and component stress.  Laird’s unique manufacturing capabilities, and filler and resin knowledge result in this unique product designed with customer applications in mind. 

Tflex HD300 material exhibits excellent surface wetting characteristics and high deflection properties ensuring low contact resistances and providing an overall lower total thermal resistance. 

Tflex[TM] HD300 is provided in thickness from 0.5mm (.020”) up to 5mm (.200”) in 0.5mm (.020”) increments as standard.  In addition, Laird can provide Tflex[TM] HD300 in multiple converted formats through approved converters and distribution networks. 

## **FEATURES AND BENEFITS** 

- 2.7 W/m K thermal conductivity 

- Low pressure versus deflection characteristics 

- Excellent surface wetting for low contact resistance 

- Minimizes board and component stress. 

- Large tolerance applications 

- RoHS and REACH compliant
