Tflex™ HD300

Tflex™ HD300

Silicone based Thermal Gap Filler

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

Tflex HD300 is provided in thickness from .5mm (.020″) up to 5mm (.200″) in .5mm (.020″) increments as standard. Non-standard increments of .25mm (.010″) are available if required, please contact Laird for information and pricing. In addition, Laird can provide Tflex HD300 in multiple converted formats through approved converters and distribution networks. Also, if your application requires, we can deliver sheets of material as large as 460mm (18″) X 460mm (18″).
