PTFE Vs.POM In Hardness

In the vast starry sky of materials science, Teflon (PTFE, polytetrafluoroethylene) and CycloMetal (POM, polyoxymethylene) are like two bright stars, each with its unique physical and chemical properties, in the field of engineering plastics to occupy a place. Today, we will discuss in depth the differences in hardness between these two materials, as well as their unique advantages in their respective fields of application.

Teflon's "tenderness": the perfect blend of flexibility and wear resistance

Teflon, this name may not be unfamiliar to many people. It has won the reputation of "king of plastics" in the industrial world for its excellent non-stickiness and chemical stability. However, in terms of hardness, Teflon is "soft as water". Usually, on the Shore D hardness scale, Teflon's hardness is between D50 and D65, which gives it excellent flexibility and elasticity.

Despite its low hardness, Teflon's abrasion resistance is impressive. This is due to its unique molecular structure and low coefficient of friction. Imagine flexible piping and gaskets made of Teflon in high-speed machinery and equipment that can easily cope with frequent bending and twisting without any fatigue. This abrasion resistance allows Teflon to show great vitality in situations that require frequent friction and wear.

In addition, Teflon has also found its place in the electronics industry and medical device manufacturing due to its good insulating properties and biocompatibility.

In the electronics industry, Teflon, as an insulating material, can effectively isolate the electric current to ensure the safe and stable operation of the circuit;

In the manufacture of medical devices, Teflon's non-stickiness makes it easy to cope with a variety of biological fluids, providing a strong guarantee for medical safety.

CycloSteel's "Firmness and Flexibility": Double Guarantee of Hardness and Wear Resistance

Unlike Teflon, which is "soft and gentle", Celestron is "strong and soft". This highly crystalline thermoplastic engineering plastic shows a clear advantage in hardness. On the Shore hardness scale of D, the hardness of Sai Steel can reach D80 or more, and even more than D90, such high hardness makes Sai Steel in the need for higher rigidity and abrasion resistance in the manufacture of mechanical parts, showing extraordinary strength.

The high hardness of Race Steel is due to its compact molecular structure and high degree of crystallinity. This enables Sai Steel to maintain its shape and properties when subjected to mechanical stresses such as shear or tension. As a result, Sai Steel has become an indispensable material in the manufacture of precision gears, slide bearings and other mechanical parts that require high strength and wear resistance.

In addition, race steel also has good thermal and chemical stability. It is able to maintain good performance at high temperatures and is not easily eroded by chemicals. This makes Race Steel widely used in chemical, automobile, electronics and other fields.
