THERM-A-GAP T630 is a fully cured, highly conformable, single component gap filler

Therm-A-Gap T630 Technical Data Sheet



Value Proposition

THERM-A-GAP Gels are highly conformable, pre-cured, single-component compounds. The cross-linked gel structure provides superior long term thermal stability and reliable performance. These unique materials result in much lower mechanical stress on delicate components than even the softest gap-filling sheets. They are ideal for filling variable gaps between multiple components and a common heat sink.
