Etched PTFE V envelope gasket

Description

PTFE V envelope gasket is made of PTFE tube or rod is cut on lathe , V-shaped skin surface is generally thin, the cross section is v-shaped lip seal ring.

Sodium treatment

Sodium treatmen that the surface PTFE V envelope gasket is treated with Sodium naphthalene liquid to give its surface a special treatment, making the liquid and surface of etched PTFE V envelope gasket to produce chemical reaction, tear off the surface of fluorine molecules. At this time, carbonization layer and some polar groups are left on the surface, so as to obtain activated PTFE. In this way,etched PTFE skived film can be bonded  with  rubber, metal, plastic, wood, non-metal and other materials. The surface of etched PTFE V envelope gasket is brown.

Advantage

• Etched PTFE V envelope gasket has small working resistance, smooth operation, high pressure resistance, vibration resistance and impact resistance.
• Etched PTFE V envelope gasket can meet the characteristics of different media and use conditions, can be multiple overlapping use, and obtain the best sealing effect by adjusting the compression force .
• Easy to disassemble and install.
• High bonding strength, long service time, long life, strong acid and alkali corrosion resistance, not easy to peel.
• Sodium treatment only produces effect on the surface, has no effect on the inside ofPTFE V envelope gasket ,does not affect its basic characteristics.

Application

• Suitable for reciprocating motion as piston or piston rod dynamic seal.
• Widely used in a variety of hydraulic systems, in addition, because of the sealing and spring of the corresponding material has good compatibility, in chemical, pharmaceutical, food and other industries have been widely used.
• Widely used in a variety of static sealing and low speed operation of sealing occasions. Good sealing effect for lower gas and vacuum.

Size：Non-standard customization, various specifications.

Etched PTFE U envelope gasket

Description

PTFE U envelope gasket is made of PTFE tube or rod is cut on lathe , U-shaped skin surface is generally thin, the cross section is U-shaped lip seal ring.
