Thermal Gap Fillers

TPUTTY 504

Soft Silicone Gel

Tputty 504 is a soft silicone gel thermal gap filler ideal for applications where large gap tolerances are present.

The silicone gel is filled with a complex matrix of ceramic fillers to yield superior thermal performance.

Tputty 504 is soft and compliant transferring little to no pressure between interfaces. Because Tputty 504 has a higher viscosity than grease it eliminates the bleed and pump-out usually associated with grease. Bond line variances can also be more easily controlled than with traditional thermal pads.

Tputty 504 can be applied like grease and is easily dispensable from a wide range of commercially available equipment including screen print syringe and automated equipment.
