One & Two-Part Thermal Conductive Gel
Fangying's one-part and two-part thermal adhesive gels are advanced thermal interface materials spanning 2–7 W/m·K. Built on silicone chemistry, they inherit excellent adhesion, weathering resistance, high- and low-temperature resistance and electrical insulation, while their high plasticity lets them conform to uneven interfaces and fill irregular gaps, meeting heat transfer needs across a wide range of applications.
One-part liquid gels deliver efficient heat conduction, low compression force and low stress, high compressibility, high electrical insulation and good temperature resistance, and they are ready for automated dispensing — simplifying assembly in high-volume electronics production.
Two-part thermal gels are pre-formed thermally conductive products based on A/B agents. Mixed at a 1:1 ratio with no by-products, they meet the need for low-stress application and high compression modulus in use. They support automated production and form good contact with electronic components during assembly, exhibiting low contact thermal resistance and excellent electrical insulation. Combining some of the advantages of both thermal pads and thermal greases, this material effectively bridges the weaknesses of each.
Key performance features

Frequently asked questions
What is the thermal conductivity of these gels?
2 – 7 W/m·K across the series (one-part: 3–7; two-part: 2–6), confirmed on the material datasheet for each grade.
Are the gels one-part and ready to use?
The one-part grade needs no mixing and can be dispensed manually or with automated equipment. Two-part grades are mixed at a 1:1 ratio with no by-products.
Do two-part gels bond to components?
Yes. Two-part grades provide adhesive bonding to metals and plastics during assembly, combining the advantages of thermal pads and thermal greases.
Can they fill uneven gaps and irregular interfaces?
Yes. Their high plasticity conforms to uneven interfaces and fills irregular gaps for reliable heat transfer.
Are the materials compliant with environmental standards?
Yes. This series complies with RoHS, halogen-free and HF-controlled requirements.
