Steam Resistance of PTFE Tape in Hot Press Forming of Plywood & MDF

As a leading source manufacturer of PTFE high-temperature fabrics, Jiangsu Aokai New Materials shares professional industry knowledge. For the hot press forming process of plywood and density board (MDF), PTFE high-temperature tape delivers excellent steam resistance, thanks to its unique material structure. Below we elaborate on its protection mechanism and core performance.

The reliable steam resistance of Aokai PTFE high-temperature tape comes from a dual protection design:

Base Barrier LayerMade of dense Polytetrafluoroethylene (PTFE) base material, the tape features extremely low water vapor permeability. It effectively blocks steam penetration and protects hot press steel plates from corrosion and damage.

High-temperature Adhesive LayerAdopting silicone pressure-sensitive adhesive, it maintains stable performance under conventional hot pressing temperatures of 130–180°C. The tape adheres firmly to surfaces and will not peel off or fail due to high-temperature steam erosion.

For practical application reference, the core performance indicators of PTFE tape in hot pressing scenarios are summarized as follows：

To further improve service life, glass fiber reinforced PTFE tape is highly recommended. With higher tensile strength, it withstands continuous tension during hot pressing, giving full play to superior steam resistance and release performance.
