PTFE Gasket

JINTAI-9960

ASTM F104:F42811-A9B5

Expanded PTFE gasket material

Use:

JINTAI 9960 is an expanded PTFE gasket material designed for use in process piping and equipment in the chemical, pulp and paper, food and beverage, and other general industries that require resistance to highly corrosive chemicals.

JINTAI 9960 is suitable for steel flanges and flanges with irregular surfaces. Style 9960 meets FDA requirements.

Specifications

Advantage:

1. Compressibility rate exceeds 60%

2. It can exert tight sealing performance in cast valves, filters and screens.

3. Compared with general filled PTFE materials, it can adapt to higher temperatures.

4. Excellent endurance performance

5. High level of torque holding capability

6. Can compensate for irregularities on the flange surface

7. Comply with Food and Drug Administration standards (FDA, United States)

8. Excellent gas sealing ability

9.Long service life

Element:

JINTAI 9960 is only made of pure PTFE resin. It is suitable for steel flanges and applications requiring high compression rate gaskets. JINTAI 9960 is also suitable for sealing flanges with irregular surfaces. This gasket does not suffer from the cold flow issues that occur with pure PTFE, or the hardness issues that occur with some other filled PTFE gaskets. It seals very well, is easy to cut, and removes cleanly from the flange after use.

Note:

The performance of the ASTM standard is measured based on a board thickness of 1/16 inches, but ASTM F38 is measured based on a board thickness of 1/32 inches. These properties can only be used as a general reference and cannot be used as a basis for acceptance or rejection. The data listed in this table are within the normal range of product performance. These data should not be used to compile technical specifications or used alone as a basis for design.

*When used for nominal pressure Class 300 or above, please consult the representative office.
