PTFE surface treatment for bonding adhesion uses two main methods: high-temperature melting (superior weather resistance, 9.5 MPa strength with coupling agent, but releases toxic gases) and sodium-naphthalene etching (5 MPa immediate adhesion, narrow 24-48 hour window, hazardous waste). Choose based on environmental control and long-term vs. short-term performance.

Testing PTFE emulsion quality involves six key indicators: solid content (60±2% per T/FSI 067-2021), pH (9.0-11.0), particle size distribution (laser diffraction/DLS), viscosity (12-30 mPa·s at 25°C), stability (centrifugal, thermal, freeze-thaw), and appearance. This guide covers standard test methods for each parameter.

To apply PTFE high temperature tape firmly on curved and irregular surfaces without bubbles and edge warping, a standardized operation process is essential, including thorough substrate pretreatment, professional application skills and proper auxiliary measures. Among them, substrate pretreatment is the most critical step, which determines about 70% of the final sticking effect.

Against the backdrop of increasingly stringent environmental regulations, PFOS/PFOA-free PTFE emulsion is an upgraded product developed to replace traditional PFOA-containing polymerization processes. It maintains the core properties of PTFE while greatly enhancing environmental friendliness and health safety.

The thermal expansion coefficient of PTFE high temperature fabric is not a fixed value. It remains relatively low at room temperature to 100°C (approximately 0.5×10⁻⁵/°C), yet rises sharply under high temperature conditions.
