Thermal Grizzly PhaseSheet PTM TG-PS-50-40 Phase-Change Thermal Pad

Thermal Grizzly PhaseSheet PTM TG-PS-50-40 — 50 × 40 × 0.2 mm Phase-Change Thermal Pad

PhaseSheet PTM is a phase-change interface material that is handled like a pad but performs like a paste: it stays solid until the chip warms past 45 °C, then flows into the microscopic gaps and stays put through thermal cycling. Supplied brand new and sealed in its original manufacturer packaging.

📋 Specifications

• Product Type: Phase-change thermal interface material (PTM) sheet
• Manufacturer Part Number: TG-PS-50-40
• Sheet Size: 50 × 40 mm
• Thickness: 0.2 mm
• Coverage: 2,000 mm²
• Phase Change: Solid at room temperature; begins to liquefy above 45 °C
• Operating Temperature Range: −75 °C to +150 °C
• Recommended Contact Pressure: Approx. 300–400 N
• Electrically Conductive: No — electrically non-conductive
• Viscosity: Very low in the liquid state
• Colour: Grey
• Burn-in: Peak performance develops and stabilises after roughly ten thermal cycles above 60 °C
• Applicator Included: Not required — cut to size and placed directly on the die or IHS

⚡ Key Features

• Solid at room temperature, so it is cut and placed cleanly — no syringe, no spreading, no mess.
• Liquefies above 45 °C and flows into surface irregularities, then holds that contact instead of pumping out.
• Only 0.2 mm thick, keeping the bond line thin between the die or IHS and the cold plate.
• Rated from −75 °C to +150 °C, covering sub-ambient benching through sustained full-load operation.
• Electrically non-conductive, so a trimmed edge that overhangs the die will not short surrounding components.
• Designed for high mounting pressure (roughly 300–400 N), which suits modern CPU sockets and GPU cold plates.
• 50 × 40 mm sheet gives 2,000 mm² — enough to cut several CPU-sized pieces from one sheet.
• Thermal Grizzly does not publish a W/mK thermal-conductivity figure for the PhaseSheet PTM series, so we list only what we can confirm. We would rather state nothing than quote a figure we cannot stand behind. If you need the exact thermal conductivity before ordering, contact us and we will check the unit in stock.
