Description

PTFE capillary tube is the use of high-quality plunger work extrusion tube, using special processing technology, so that the steel tube and plastic tube closely combined, can withstand positive pressure 1.6mpa, negative pressure: 77Kpa.

Sodium treatment：Sodium treatmen that surface of PTFE is treated with Sodium naphthalene liquid to give its surface a special treatment, making the liquid and surface of etched PTFE capillary tube 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 capillary tube is brown

Advantage

• Good temperature resistance, Corrosion resistant, non-toxic.
• 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 of PTFE capillary tube,does not affect its basic characteristics.
• As a result of sodium treatment of PTFE to maintain the low friction coefficient of the original material, machine operation is light, anti-climbing, small vibration.

Application

Used for heat exchanger, valve core, chemical raw materials, pharmaceutical intermediates, corrosive material transportation, gas transportation.
