PTFE Powder, A New Choice For Wear-resistant Modification

PTFE powder, that is, polytetrafluoroethylene (PTFE) powder, is mainly based on its unique physical and chemical properties in the principle of wear-resistant modification in rubber. The following is a detailed explanation:

1、Wear-resistant modification caused by physical properties

（1）Extremely low friction coefficient:

PTFE powder has an extremely low friction coefficient, which is the key to its wear resistance. When PTFE powder is added to rubber, it can reduce the direct contact between rubber and other materials, thereby reducing friction and wear.

（2）Self-lubricity:

PTFE powder can form a lubricating film during the friction process. This film has self-lubricity, which can further reduce the friction coefficient and reduce wear.

（3）Good dispersibility:

PTFE powder is easy to be evenly dispersed in the rubber matrix, thereby ensuring the consistency of wear resistance in the entire rubber product.

2. Wear resistance modification caused by chemical properties

（1） Chemical inertness:

PTFE powder has extremely high chemical stability and is stable to almost all chemicals and solvents except alkali metals. This means that during the use of rubber products, PTFE powder will not fail due to chemical reactions, thus ensuring its long-lasting wear resistance.

（2）Non-stickiness and scratch resistance:

PTFE powder has excellent non-stickiness and scratch resistance, which makes it difficult for rubber products to adhere or scratch when subjected to external forces, thereby improving its wear resistance.

3. Specific application effects in rubber

（1）Improve friction and wear performance:

By adding an appropriate amount of PTFE powder, the friction and wear performance of rubber products can be significantly improved, extending their service life.

（2）Improve mechanical properties:

PTFE powder can also give rubber products good mechanical properties, such as tear strength, tensile strength, etc., thereby enhancing its overall performance.

（3）Broaden the scope of application:

Due to the addition of PTFE powder, rubber products can be used in more occasions that require wear resistance, corrosion resistance and other properties, such as seals, gaskets, wear-resistant plates, etc.

In summary, the principle of wear-resistant modification of PTFE powder in rubber is mainly based on its extremely low friction coefficient, self-lubrication, good dispersibility and chemical inertness. These characteristics make PTFE powder an important wear-resistant modifier in rubber products, which can significantly improve the wear resistance and service life of rubber products.
