During the production of Teflon (PTFE) tape, several critical steps must be followed to ensure quality and performance:

High-Temperature Validation: Confirm the tape’s heat resistance (typically 210–260°C) aligns with requirements. Overheating

in production lines may leave adhesive residue; regularly inspect temperature sensors.

Coating & Curing: Strictly adhere to pressure-sensitive adhesive (PSA) curing parameters during coating. Insufficient curing time

or excessive line speed can weaken adhesion between the adhesive, substrate, and PTFE layer. Semi-finished products should rest

for 2–3 days after slitting to ensure bonding.

Adhesive Preparation: Uniformly mix polyurethane, acrylics, and solvents under controlled heating to create consistent adhesive.

PTFE Substrate Lamination: Use pressure rollers and hot air blowers to bond adhesive-coated paper/film tightly to the PTFE

substrate.

Curing & Testing: Bake laminated tapes in ovens to fully cure the adhesive. Conduct peel tests to verify adhesion strength and

quality compliance.

In summary, strict control over raw materials, process parameters, and testing ensures optimal Teflon tape performance.
