Modified Polytetrafluoroethylene (RPTFE)
PTFE has excellent performance, but it also has some shortcomings, such as poor creep resistance, easy wear, low mechanical strength and so on. RPTFE composite can be prepared by filling some reinforcing agents in PTFE (or PCTFE). These fillers can greatly improve the mechanical strength of PTFE, thus expanding the use of such materials. Fillers include carbon fiber, graphite, tin bronze powder, glass fiber, molybdenum disulfide, polyphenyl ester, para-polyphenyl, polyimide, carbon powder, aramid fiber, calcium sulfate, stainless steel powder, silicon powder, pigments and so on. Different fillers have their own characteristics. They can provide suitable materials according to the requirements of customers' working conditions, and their shapes and sizes can be customized at will.| Filled materials | Common filled ratio (Quantity %) |
Main performance |
| Bronze | 40,60 5,10,15 |
Increase hardness and wear resistance; Increase 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 | 10,15,25 | Improves the deformation under load;Reduces initial wear; Improves thermal and electrical conductivity |
| Glass Fiber | 10,15,25 | Increases compressive strength,rigidity and wear. Reduces creep and cold flow;improve dimensional stability |
| Carbon Fiber | 5,10,15 | Increases compressive strength,hardness,wear,and load properties. Reduces creep and cold flow |
| POB (Polyphenyl ester) |
5,10,15 | Improve the lubricaiton performance;Enhance the mechanical strength; Increase using temperature |
| BaSO4 | 5,10,15 | Increase 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 | |
