   Learn more about PTFE: PTFE is a kind of excellent chemical resistance and resistance to high and low temperature fluorocarbon chemicals, even when it is exposed to the air also can't bad,PTFE showed high chemical stability, resistance to almost all the invasion of the acid and alkali chemical material such as, outstanding is not sticky, abnormal lubricity and excellent electrical insulation properties, aging resistance and radiation resistance, small water absorption characteristics are known as "plastics king".Widely used in aerospace, petrochemical, machinery, electronics, electrical appliances, construction, textile and other fields.It is because of these features, it appeared was secret applications in military industry, it was not until the 1950 s application to static seal, compared with general spiral seal, it is a kind of very good elastic sealing material.     Features:   1. The body is designed, and half axle shaft without pin connections.
2 disc outside line 3-5mm thick PTFE seat and disc, using ball seal. Smooth transition open, reduce the friction torque, reduced, more reliable seal.
3 all contact with the media part adopts the F4 materials, and guarantee and medium complete isolation and long service life.
4. According to user's requirements, the choice of very convenient installation and drive mode.
