Thickeners a ɛwɔ PTFE emulsion mu no di dwuma anan a ɛho hia: suspension stabilization (siw PTFE asinasin a ɛyɛ den no ano), shear-thinning suban (viscosity a ɛkorɔn wɔ ahomegye mu, ɛba fam wɔ basabasayɛ ase ma ɛyɛ mmerɛw sɛ wɔde kata so), penetration depth control (ɛhwɛ resin loading so wɔ fiberglass ntama so), ne film uniformity (siw mpaapaemu ano bere a ɛreyow). Ahwehwɛde a ɛho hia: ɛsɛ sɛ thickeners porɔw koraa wɔ ~380°C sintering temperature, gyaw zero ash residue na ama coating ahotew ne anyinam ahoɔden insulation.

PTFE emulsion su a wɔsɔ hwɛ no fa nsɛnkyerɛnne atitiriw asia ho: nea ɛyɛ den (60±2% wɔ T/FSI biara mu 067-2021), pH (9.0-11.0), nneɛma nketenkete kɛse kyekyɛ (laser diffraction/DLS), viscosity (12-30 mPa·s wɔ 25°C), sɛnea ɛyɛ den (centrifugal, thermal, freeze-thaw), ne sɛnea ɛte.
