Common Quality Defects During PTFE High-Temperature Fabric Drying – and How to Prevent Them

Drying is a critical step in PTFE high-temperature fabric production. Common defects include: cracking (too fast drying, surface skinning), coating migration (particles move to surface, weak internal bond), pinholes/blisters (trapped air or steam), white spots and chalking (surfactant migration or incomplete fusion), yellowing/coking (overheating of additives), delamination (shrinkage stress exceeds adhesion), orange peel (poor leveling), warpage (uneven shrinkage), surface dry but interior wet (skinning traps moisture), and thick edges (coffee-ring effect). Solutions involve controlled drying profiles, proper ventilation, and substrate pretreatment.

How PTFE Tape Cut End Face Structure Affects Adhesive Oozing and Edge Lifting

The cut end face structure of PTFE high-temperature tape directly affects adhesive oozing and edge lifting during application. Poor slitting (dull blades, improper angle) creates glue filaments, thins the edge adhesive layer, and exposes fiberglass burrs – leading to oozing, weak bonding, and lifting under heat or tension. Irregular end faces (wavy, protruding) cause uneven pressure distribution, driving adhesive creep during storage. The ideal end face is smooth, flush, and damage-free – acting as a seal that locks the adhesive and ensures full edge bonding.

Common Auxiliaries Used in PTFE Emulsion Impregnation – A Complete Guide

PTFE emulsion impregnation of fiberglass fabric requires various auxiliaries to achieve uniform coating, strong adhesion, and defect-free surfaces. Key additives include: wetting agents (reduce surface tension, improve penetration), thickeners (control viscosity and coating weight), pH regulators (stabilize emulsion at pH 9-10), silane coupling agents (enhance adhesion to glass), film-forming aids (PFA/FEP for sintering), functional fillers (wear resistance, conductivity), defoamers (prevent pinholes), and humectants (slow drying). Selection depends on substrate and performance requirements.
