Polytetrafluoroethylene (PTFE)

Product Description

Teflon film pressure drivepipe is made by molding polyflon through film pressing method under ordinary temperature, and then sinter it into different specifications of drivepipes.

1. Usage: -180C----+250Canti-corrosion and medium sealing pieces.

2. Appearance:
It is homogeneous in structure, smooth in appearance, without crack, air bubble, Delamination and mechanical scratch. The arched degree of annular tube is not more than 2 millimeters but permits to a few exogenous impurity.

3. The negative allowance of annular tube of Teflon is not less than 1 millimeters and the positive allowance of inner diameter is not more than 1 millimeters.
