Parker Chomerics THERM-A-FORM™ T644 is a two-component, high thermal conductivity (1.2 W/m-k), low modulus, silicone material ideal for transferring heat from fragile electronic components.

THERM-A-FORM™ thermally conductive silicone elastomer products are dispensable form-in-place compounds designed for heat transfer without excessive compressive force in electronics cooling applications. These versatile liquid reactive materials can be dispensed and then cured into complex geometries for cooling of multi-height components on a PCB without the expense of a molded sheet. Each compound is available in ready-to-use cartridge systems, eliminating weighing, mixing, and degassing procedures.

Product Attributes:
• Very low modulus material for transferring heat from fragile electronic components
• Highest pot life of all potting compounds (6 hours)
• Boron Nitride filled material

Features and Benefits:
• Dispensable form-in-place gap filling, potting, sealing, and encapsulating
• Excellent blend of high thermal conductivity, flexibility, and ease of use
• Conformable to irregular shapes without excessive force on components
• Ready-to-use cartridge system eliminates weighing, mixing, and de-gassing steps
• Variety of kit sizes and configurations available to suit any application (handheld twin-barrel cartridges, Semco® tubes, and pneumatic applicators)
• Vibration damping
