general assembly drawing of thermal grease vertical kneader structure

Why are vertical kneaders recommended for the production of thermal grease?

1. Strong mixing capability for high-viscosity materials

Utilizing an intermeshing twin-shaft (or triple-shaft) mixing structure, the system exerts intense shear, compression, and folding forces on highly filled, high-viscosity materials, easily handling:

High-viscosity materials (50,000–2,000,000 cP)
Highly filled thermal conductive silicone grease
Thermal conductive gels
Thermal conductive potting compounds
High thermal conductivity silicone rubber

2. Vacuum degassing to enhance thermal conductivity

Air reduces the thermal conductivity of thermal grease, making degassing crucial.

Thermal grease vertical kneader is equipped with a vacuum system that allows for continuous vacuuming during the mixing process:

Removes air
Eliminates micro-bubbles
Increases product density
Enhances thermal conductivity
Improves long-term product stability

3. Contamination-free Design

One of the key advantages of the vertical structure is: the spindle seal does not come into direct contact with the material.

Compared to sigma mixer, this effectively prevents:

Product contamination caused by seal wear
Frictional heat generation
Contamination by lubricating oil

It is particularly suitable for the production of high-quality, electronic-grade thermal grease.
