By the building of the firm in excess of two decades, we have now total developing outlines of PTFE gasket washers substance consist of expanded PTFE gasket, PTFE shaped gaskets, filled PTFE gaskets, PTFE gaskets with silica filler, PTFE gaskets with fiberglass fibers, PTFE gasket with aluminosilicate microspheres, PTFE gaskets with barium sulfate filler, PTFE gaskets with graphite filler.  As we carry sizeable amount of uncooked PTFE Resin resources for producing PTFE gaskets materials, which means your orders placed could be supplied in very short period of time around 3 to 1 week.  And by using our superior PTFE making devices and our skilled competent technological employees, the price of the ptfe gaskets components we make quite lower than other providers, so that you can definitely have the PTFE gaskets you want in top quality and low-cost value from us zhinhong sealing.

Expanded PTFE Gasket

We construct and offer a vast and stock range of expanded PTFE gasket material, and that is suitable for almost any industry from the least complicated towards the most complex programs as well as conditions. The exceptional material properties of expanded PTFE gasket material make it possible for it for a strong flexible material and can be resistant to virtually all chemicals and corrosive media, and withstands extraordinary temperature as well as pressures.

Expanded PTFE gasket material is made for easy setting up, saving charge and also time, and lowering tools repairs and maintenance and downtime through its long and also efficient service life. And the Expanded PTFE gasket compression is 55%.

Expanded PTFE Gasket Properties and Advantages

Expanded PTFE gasket is made of completely pure PTFE, expanded via a exceptional method in a steady, highly fibrillated structure. After compression, the fibrils lock together produce a sturdy, standard material, impervious to gases and liquids.

It seals under extreme temperatures, pressures and against corrosive media, just where traditional materials would break down. Also during program, the material is incredibly proof against creep, relaxation and cold flow - issues which are often associated with other gasket materials, especially virgin or filled PTFE.

Expanded PTFE gasket can be working during the entire pH range, proofed against thermal cycling, non-contaminating and therefore is often used in virtually any industry, sealing the simplest to the most difficult of gasket applications.

Application:

Expanded PTFE gasket material is an expanded PTFE material intended for use in method piping as well as tools in chemical, pulp and paper, food and beverage and other general industrial applications where resistance to highly aggressive chemicals is required. Expanded PTFE gasket material is suitable for use in steel flanges and flanges with irregular surfaces as well as it conforms to FDA requirements.

Operating Limits of EPTFE Gasket

Gasket Temperature: -240ºC to +260ºC
Internal Pressure: From full vacuum to 207 bar
Media pH Value: 0 to 14

Expanded PTFE Gasket Dimension

The thickness of expanded PTFE gasket material is usually 0.5mm, 1mm, 1.5mm, 2mm, 2.5mm, 3mm, 4mm, 5mm, 6mm, 8mm, 10mm. And we can make gasket from 1/2 inch to 24 inch, the max diameter can be 2000 mm

Virgin PTFE Gaskets

For longer than 20 years, our gaskets production organization has produced unique PTFE gaskets that meet up with consumer specifications for effectiveness, dependability, and cost. All of our virgin PTFE gasket are cut from 100% PTFE Teflon gaskets sheet with all range of dimension sizes, thickness from 0.5 mm to 100mm all is available. Virgin PTFE gaskets are chemically inert as well as water-resistant, but tend to deform under use. For improved resistance to creep and cold flow, we recommend Gore GR gaskets instead. Gore GR sheet gasketing is an expanded PTFE for industrial applications.

We can produce plus supply PTFE Teflon gaskets from 100% virgin PTFE in excellent cost, or suggest compounds that contain PTFE and various fillers for increased resistance to strong acids or caustics. In addition, we can source expanded PTFE Teflon gasket material that is much easier to compress and conforms to tough surface areas.

emperature Range Of Virgin PTFE Gaskets

The functioning temperatures of Virgin PTFE gaskets ranges from -200⁰C to +260⁰C. It is the most commonly known non-stick material by using a coefficient friction comparable to wet ice on wet ice. Most of the people commonly utilise PTFE through a commonly seen trademark: Teflon, which is a PTFE coating for non-stick household items.

Why Should You Use PTFE As A Gasket Seal?

Virgin PTFE Gaskets are chemical resistant. Pure virgin PTFE gaskets can be used in the most corrosive of environments and will not contaminate the most sensitive medium. PTFE is utterly insoluble and possesses high intrinsic purity and can be made with no pollution for ultra-pure or corrosive purposes.

Virgin PTFE Gaskets are completely resistant to attack by all chemicals excluding molten alkali alloys and also a few fluorine elements at raised temps and pressures. It is unaffected by lubricants, hydraulic fluids, plane or rocket gasoline as well as atmospheric problems.

Which are the Disadvantages of Virgin PTFE Gaskets?

While virgin PTFE gaskets are a fantastic selection for numerous programs, it can have a very several disadvantages to be considered: It includes almost no plastic ability to remember and is subject to creep, which can be worthwhile when utilized for a seal, nonetheless to limit this effect a version of PTFE with fillers should be used. virgin PTFE gaskets is referred to as gentle and can harm or distort when being clamped. It is going to not be described as being hard or having a high tensile strength.

Applications of Virgin PTFE Gaskets

Virgin PTFE Gaskets are commonly used in pipework and flanges where chemicals are present, PTFE gaskets have an extremely low coefficient of friction and good resistance to moisture and corrosion. The anti-stick properties of the material mean PTFE is commonly found in applications with parts that have linear or rotary movements.

Can PTFE Gasket be Used in Food Applications?

Because we all are aware of PTFE is Teflon® lining for cooking equipment which is popular globally. It comfirms to FDA standard.

PTFE Gasket with Silica Filler

PTFE gasket with silica filler is made with 100% Virgin PTFE with Silica as the filler. Compared to conventional Virgin PTFE, this PTFE gasket with silica filler material is suitable for considerably higher pressure and temperature applications. PTFE gasket with silica filler is ideal for standardisation because of excellent chemical resistance and mechanical characteristics. This material offers resistant to cold flow and creep, excellent bolt-load retention, outstanding dimensional stability under thermal stress, and resistance to wear and abrasion.

Features and Benefits:

PTFE gasket with silica filler is a tight seal and has improved performance over conventional PTFE, it can reduce product loss and emissions and creep relaxation. PTFE gasket with silica filler has unique manufacturing process that minimizes cold flow problems typical of skived and expanded PTFE sheets. This gasket has excellent bolt torque retention and can withstands a wide range of chemicals for extended service life in a wide variety of applications.
