PTFE Kolbenring

Our company has more than five years of experience to produce PTFE piston ring. The products can be widely used in many kinds of shock absorbers from automobiles. The middle part is the powder metallurgy and the outside is the PTFE material, which has the advantage of low friction coefficient, good wear resistance and so on. These kinds of products can be used in high temperature without any problem. The products have passed the Test center,Shang hai Plastic Research Institute. We can design and produce the PTFE piston ringsaccording to the customer's demand. Here is the physical properties of our product: Tensile strength≥23N/mm2Carrying capacity≥15N/mm3Working temp.-80°C to 260°CFriction coefficient(dry)≤0.16μFriction coefficient(oil)≤0.05μ Materials: PTFE+BRONZEPTFE+BRONZE+ACID TREATMENTPTFE+CARBON FIBERPTFE+GLASS FIBER+INTENSIFIEROTHER FILLERSYou can choose one kind of above material to design your pistons.
