GT-TIM Graphene Thermal Interface Material

SHT Smart High Tech AB is a company based in Gothenburg, Sweden, that makes graphene-based thermal interface materials under the GT-TIM name. The materials target hardware where heat limits performance, such as servers, electronics, wireless equipment, thermal testing and burn-in, crypto mining and rendering.

GT-TIM uses a patented enhanced graphene formula for through-plane conductivity, with 200 W/mK stated on the site and thermal resistance of 2 Kmm2/W at 200 um and 40 PSI. Grades include GT90, GT90PRO and GT90SOFT, with GT200, GT300 and GT50R as prototypes, plus semi-insulating and immersion-ready variants. B2B sales run through Henkel's Loctite brand and B2C through Thermal Grizzly's Kryosheet.

• GT90 family: GT90, GT90PRO and GT90SOFT graphene thermal interface grades.
• High conductivity: 200 W/mK through-plane and 2 Kmm2/W at 200 um and 40 PSI.
• Variants: semi-electrically insulating and immersion-ready versions.
• GT50R: prototype launched in 2026-06 for battery cooling and power electronics, made from recycled waste material.
• Channels: B2B through Henkel's Loctite brand, B2C through Thermal Grizzly's Kryosheet.

Thermal interface layers for servers and GPU racks in Vietnamese data centres. Heat management in electronics assembled by contract manufacturers in Vietnam. Cooling of EV battery packs and power electronics.

Through-plane conductivity of 200 W/mK stated by the company. Up to 10 C lower hardware temperature, which the company says could double hardware lifetime. Performance claimed to hold over time, unlike thermal grease, indium or phase-change materials. Up to 50% less material for the same performance. ISO 9001, 14001 and 45001 certified.

Server, data centre and power-electronics heat densities keep rising with AI workloads, pushing demand for thermal interface materials that last longer than grease. Vietnam is expanding electronics assembly and data centre capacity, which makes TIM suppliers relevant to local manufacturers and operators.
