 FAQ
HONYFLUO®PTFE sheet or rod (chemical name is polytetrafluoroethylene, commonly known as Teflon) is a semi-crystalline fluoroplastic with many unique properties. It has very high thermal stability and chemical resistance, as well as a high melting point (-200 to +260°C, short-term up to 300°C). In addition, PTFE products have excellent sliding properties, excellent electrical resistivity and non-stick surface. However, compared with other plastics, this material has lower mechanical strength and higher specific gravity. PTFE plastic can be modified by adding glass fiber, carbon or bronze to improve the mechanical properties of the material. Due to its structural characteristics, PTFE is usually compression molded, and then the material is machined with cutting/processing tools
Teflon Sheet Rod Feature
Very high chemical resistance
Excellent high temperature resistance
(-200+260°C, short-term up to 300°C)
Very low coefficient of friction
Very low surface tension (almost no material will stick to PTFE, it is difficult to stick or weld)
High thermal expansion coefficient
Relatively low strength/rigidity
Low dielectric constant
Flame retardant
PTFE is one of the most commonly used and most important fluorine-containing plastics and is widely used in various application fields. It is a commonly used material in sliding applications, especially in environments where components need to withstand chemical stress.

As a wear-resistant seal, it is used in turbines. In unfavorable chemical environments, seals and shields made of HONYFLUO®PTFE tubing have reliable performance and greatly improve the efficiency of turbomachinery. (Replace the previous materials: aluminum, bronze, babbitt alloy)
Because the performance and life are significantly better than other PTFE, the transmission and power steering seals processed by HONYFLUO®PTFE have been widely used by top European car manufacturers. (Replace the previous material: GF PTFE)
Fluorosint® Family
The Fluorosint® range of enhanced PTFE materials was developed to fill the performance gaps where unfilled as well as low-tech, filled PTFE-based polymers underperform. Each Fluorosint® material was specifically designed to excel in demanding bearing and seal applications. While each of Fluorosint® grade possesses the great chemical resistance and compliance of standard PTFE, each material offers unique properties resulting from our proprietary process in which we chemically link synthetically manufactured mica to virgin PTFE. These enhancements give individual Fluorosint® grades superior performance properties, ranging from outstanding dimensional stability, to improved wear performance, to higher load bearing capabilities.
