JacobsParts Inc. Protronix Series 9 PST-G 30G Thermal Paste

SKU CH-QMMM-TR0F0

High-density thermal compound with 5.15 W/m-K conductivity and 30 g syringe for extreme cooling

  • High thermal conductivity at 5.15 W/m-K for efficient heat transfer
  • 62% more conductive than Series 7 for demanding applications
  • Low thermal resistance under 0.004 °C-in²/W improves contact performance
  • Operates from -50 °C to 340 °C for extreme environments
  • 30 g syringe with 45% metal oxide provides long-lasting supply

Protronix Series 9 30G Syringe

The Protronix Series 9 thermal compound delivers a 62% conductivity improvement over the previous Series 7 formulation. Its high-density paste suits extreme environments where maximum heat transfer is required. The 30 gram syringe provides enough material for multiple CPU or GPU applications.

Non-conductive high-density formula

The compound is non-electrically conductive, non-corrosive, non-toxic, flame retardant and odorless with low oil content. It will not cure or volatilise over time, so it remains stable through repeated thermal cycles. Builders can apply it directly from the syringe without risk of shorting adjacent components.

5.15 W/m-K conductivity headroom

Thermal conductivity exceeds 5.15 W/m-K while resistance stays below 0.004 °C-in²/W, giving ample margin for high-wattage processors and graphics cards. The 45% metal oxide content supports continuous operation from -50 °C up to 340 °C. The paste will not meet the needs of users who require a pre-applied pad or a lower-viscosity liquid metal alternative.
