Single-Component Thermal Gel (Putty)

Single-Component Thermal Gel (Putty)  

Single-component thermal gels — often referred to as thermal putty — are soft, non-curing, highly compliant thermal interface materials. These materials are ideal for applications where you need precise, low-stress, and consistent thermal contact between components and heat sinks, even over large surface areas or irregular gaps.

This type of gel is designed to flow and fill microscopic gaps without curing, making it easy to apply, rework, and reuse. It’s especially useful for mass production, thanks to its compatibility with automated dispensing equipment.

Key Features & Benefits:

• 🌡 Medium to High Thermal Conductivity
  Typically offered in a range from 2.0 to 10.0 W/m·K, making it suitable for a wide variety of thermal management demands — from consumer electronics to industrial power systems.
• 🧽 Soft, Flowable, and Compressible
  Easily conforms to surface irregularities and fills air pockets for low thermal resistance — especially useful where surfaces aren’t perfectly flat.
• 🔁 Non-Curing & Reworkable
  Remains in its gel-like state permanently, enabling fast adjustments, repairs, or replacements without residue or damage.
• 🎯 Precision Dispensing
  Supports automated dispensing for clean, repeatable manufacturing — ideal for scaling up production with controlled volume and placement.
• ⚡ Good Electrical Insulation
  Ensures safe separation between thermally active and electrically sensitive components.
• 🛡 Low Mechanical Stress
  Applies minimal pressure on components, making it safe for delicate chips, modules, or PCBs.
• 🌿 Environmentally Compliant
  Fully RoHS, REACH, and Halogen-Free compliant for safe use in regulated industries.

Common Applications:

• CPUs, GPUs & Logic Boards
• Power Supply Units & Converters
• LED Lighting Systems
• Electric Vehicles & Battery Modules
• Consumer Electronics & Laptops
• Telecom & 5G Infrastructure

Use a single-component thermal gel when your application calls for high thermal performance, reworkability, and automation-friendly dispensing. It's perfect for high-volume production, tight mechanical tolerances, and situations where mechanical stress must be minimized while still ensuring solid thermal contact.
