Polytetrafluoroethylene (PTFE) suspension micro-powder is a white, low-molecular-weight, free-flowing powder with an average particle size ranging from 0.1 μm to 5 μm. It is obtained by suspending polymerization of PTFE resin into tiny particle powder. The stable molecular structure of (-CF2-CF2-)n endows it with excellent properties. 

Properties of PTFE Micro Powder 

1.Good electrical insulation

It has excellent electrical insulation performance and can be applied in fields such as electronics and electrical engineering where high insulation performance is required. 

2.Excellent self-lubricating properties

With an extremely low coefficient of friction, it is one of the materials with the smallest coefficient of friction among solid materials, and it has excellent self-lubricating properties, which can reduce friction and wear between components. 

3.Good thermal stability

Wide operating temperature range, maintaining stable performance within the temperature range of -200℃ to +260℃. 

4.Strong non-stick property

With low surface tension, it has excellent non-stickiness, making it difficult for other substances to adhere and easy to clean. 

5.Good dispersibility

After special surface treatment, it has excellent dispersibility in various solvents and materials and can be evenly distributed in the matrix material. 

Application fields of PTFE micro powder 

1.In the field of coatings, the addition of PTFE micro powder to coatings can enhance their weather resistance, chemical corrosion resistance, scratch resistance, and non-stickiness, among other properties. It is used in the production of non-stick cookware coatings, exterior wall coatings for buildings, and industrial anti-corrosion coatings, etc. 

2.In the field of plastics, PTFE micro powder with an extremely low coefficient of friction, serves as an additive for plastics, enhancing their wear resistance, lubricity, and anti-sticking properties. It is applied in engineering plastics, nylon, POM, and other materials, thereby extending their service life. 

3.In the field of rubber gaskets, PTFE micro powder has a relatively high hardness and excellent wear resistance. When added to rubber, it can effectively enhance the wear resistance of rubber gaskets, enabling the gaskets to maintain good performance in harsh working conditions and thereby improving the reliability and stability of equipment. 

4.In the field of lubrication, shock absorbers often need to withstand significant pressure and vibration. Adding PTFE micro powder can enhance their wear resistance and self-lubricating properties. For instance, in some high-load and high-frequency friction working environments, using plastic gears with added PTFE micro-powder can effectively reduce gear wear and extend their service life.
