Description:
PTFE is the mostly consumed category of florin plastics, Which has the lowest coefficient of friction in all the engineering plastics, Whose long-
term working temperature can reach 200 to 260℃.
PTFE material has the following main characteristics: the excellent chemical corrosion-resistance, which is able to endure All kind of chemistry
material. And it has rather good electricity-resistance, which is not affected by the temperature and is called "Kind of plastics", PTFE plastic has
excellent corrosion-resistance, aging-resistance, high(low) temperature resistance, good lubrication and insulation, non-adhesiveness,
toxicological harmless. It is widely used in industries like aviation, chemical industry, electric and electronics, bridge, mechanical manufacturing,
textile, paper making, ceramics etc.

PTFE filled with other materials:
| Filled materials | Common filled ratio ( Quantity %) | Main performances |
| Bronze | 40, 60 | Increases hardness and wear resistance; Increases dimensional stability and compressive strength; Not suitable for corrosive or electrical applications |
| Carbon | 5, 10, 15 | Increases compressive strength, hardness, wear, and load properties. Good chemical resistance; Improves electrical properties. |
| Graphite | 5, 10, 15 | Improves the deformation under load; Reduces initial wear; Improves thermal and eletrical conductivity |
| Glass Fiber | 10, 15, 25 | Increases compressive strength, rigidity and wear. Reduces creep and cold flow; Improve Dimensional Stability. |
| Carbon Fiber | 10 , 15, 25 | Increases compressive strength, hardness, wear, and load properties. Reduces creep and cold flow |
| POB (polyphenyl ester) | 5, 10, 15 | Improve the lubrication performance; Enhance the mechanical strength; Increase using temperature |
| BaSO4 | 5, 10, 15 | Increases compressive strength, hardness and wear resistance Reduces creep |
| SiO2 | 5, 10, 15 | Increases hardness and wear resistance; Improve Dimensional Stability. |
| Glass beads | 5, 10, 15 | Reduces creep and cold flow; Lower density Increases hardness and wear resistance; |
| Others materials | PEEK(polyetheretherketone), PI(Polyimide), MoS2 are also ok | |
