ПТФЭ поршневые кольца

Our company has more than five years of experience to produce PTFE piston rings. 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 canbe usedin high temperature without any problem. The products have passed the Test center, Shang hai Plastic Research Institute. As soon as we get the new samples, we will send to shanghai to have a test. We will improve ourselves step by step. We can design and produce the PTFE piston rings according to the customer's demand. Here is the physical properties of our products Tensile strength≥23N/mm2Carrying capacity≥15N/mm3Working temp.-80°C to 260°CFriction coefficient(dry)≤0.16μFriction coefficient(oil)≤0.05μ More details, please come into our website http://www.xyptfe.com
