TflexTM 300 Series
Thermal Gap Filler
UNIQUE SILICONE GEL OFFERS COMPLIANCY, THERMAL RESISTANCE
Tex™ 300, at pressures of 50psi, will deect to over 50% the original thickness. This high
rate of compliancy allows the material to “totally blanket” the component, enhancing
thermal transfer. The material has a very low compression set enabling the pad to be reused
many times.
Tex™ 300, in achieving its stellar compliancy, does not sacrice thermal performance.
With a thermal conductivity of 1.2 W/mK, low thermal resistances can be achieved at low
pressures.
Tex™ 300-H is offered with a hard, metallized liner option for easy handling and improved
rework. The metallized liner’s lower coefcient of friction also allows for easy assembly of
parts that must slide together, such as a card into a chassis.
FEATURES AND BENEFITS
• Extreme compliancy allows material to “totally blanket” component(s)
• Thermal conductivity of 1.2 W/mK
• Available in thicknesses from 0.020” - 0.200” (.5mm – 5.0mm)
• Low compression set enables the pad to be reused many times
APPLICATIONS

• Telecommunication hardware
• Flat panel displays
• Memory modules
• Power conversion equipment
• Set top box
• Lighting ballast
• Automotive electronics
• LED lighting
• Handheld electronics
