The History and Applications of Liantuo PTFE Rod

Liantuo PTFE Rod are an excellent product. PTFE-polytetrafluoroethylene was discovered by Dr. Roy Plunkett of DuPont Research Laboratory on April 6, 1938. The original PTFE was further developed by Dupont and released as a product in 1945.

The product is highly resistant to chemical corrosion and can handle temperatures above 500 ° C. One of PTFE's first household items is the "PTFE coated frying pan". Although the pot works very well, it is different from the PTFE rods and plates we supply. It is sprayed on almost black coating, pure PTFE rods and sheets in the PTFE round bar steam valve package is bright white how to use industrial PTFE plastic rods how to use industrial PTFE plastic rods PTFE gaskets and steam packaging.

Because PTFE has high temperature and chemical resistance, it is usually used for valve applications. From simple steam / hot water valves to high temperature, fluid handling industries caustic chemical valves. This material is semi-rigid to rigid plastic and can be easily machined - one of the easiest to use plastic. The PTFE rod can be machined into very close tolerances on most small diameter rods with a diameter of +.002 "/ - .00". Chemical resistance is one of the key properties associated with materials. In flakes or flakes, PTFE is used as a gasket material for high heat and chemical resistant flanges and seals.

There are two kinds of PTFE rods .

One is manufactured by paste extruding method in diameter from 4mm to 9mm and the other is made by ram extruding method in the diameter from 10mm to 150mm;rods over diameter 150mm are manufactured by moulding.

PTFE is the most chemical-resistant plastic of all known plastics.it does not age.

PTFE has a wide range of practicable temperature from-180℃ to+260 ℃and a wax-like surface to which anything hardly sticks.

PTFE has the lowest coefficient of friction of all know solid materials.

It has the best electrical properties of all plastics.
