Thermal Gap Fillers

Thermal Gap Fillers



Tflex CR200 is a two-part silicone-based thermal gap filler tha t has low viscosity prior to curing. Tflex CR200 is ideal for applications where large ga p tolerances are present. The low viscosity makes it ideal for applications in which the components cannot withstand high pressure during assembly. The mixed material will cure at room temperature or can be accelerated with the addition of heat. The Tflex CR200 composit ion provides excellent thermal performance and compliance.

• Soft and compliant transferring little to no pressure between interfaces

• 2.0 W/mK thermal conductivity

• Available in 50cc & 200cc cartridges and 20 kg pail kits

• Easy to dispense
