  • Soft 30–55 Shore C hardness conforms to uneven surfaces and fills air gaps
  • Reusable pad with natural viscosity allows easy installation and rework

Product Identity

The Lirealar thermal pad measures 120x20mm with a 1.0mm thickness and provides 12.8 W/mK thermal conductivity. It is intended for builders and technicians who need a high-conductivity interface for laptop heatsinks, GPU modules, CPU packages or LED coolers.

Build Quality & Mounting

The grey silicone pad weighs 15g and has a density of 3.1±0.2g/cc with hardness rated 30-55 Shore C. It is non-conductive, non-corrosive, non-curing and non-toxic, with a breakdown voltage above 9.8kV at 1mm thickness. Natural viscosity allows easy placement and reuse while insulating components safely across a -40°C to +200°C operating range.

Accessories & Software Impact

The package supplies a single multi-purpose pad that fills gaps between uneven surfaces and rough textures without additional compounds. Its compressible elasticity bridges air gaps to lower contact thermal resistance, and the material resists wear, fire and metal damage while remaining reusable for future maintenance.

Questions about this item

What does the 12.8 W/mK thermal conductivity mean for heat transfer between a GPU and heatsink?

The 12.8 W/mK rating indicates high thermal conductivity for a silicone pad, efficiently filling microscopic air gaps between the GPU die and heatsink to lower contact resistance and improve heat flow.

Will the 120x20x1.0mm dimensions and 30-55 Shore C hardness fit my laptop GPU gap?

The pad measures 120 mm by 20 mm with a 1.0 mm thickness; its 30-55 Shore C hardness provides enough compliance to conform to uneven surfaces while maintaining structural integrity during assembly.

How do I install the pad correctly without tearing the 1.0mm material?

Clean both surfaces with isopropyl alcohol, peel the protective film, align the 120x20 mm pad over the chip, and apply even pressure — do not stretch the 1.0 mm thick silicone during placement.
