Kab lus no sib piv qhov tseeb ntawm peb txoj kev ntsuas kev ntsuas kev ntsuas rau silicone siab-rhiab nplaum nplaum. Cov kuab tshuaj extraction (gel cov ntsiab lus) ntsuas insoluble network feem ntawm Soxhlet extraction - overestimates vim lub cev entangled segments yuam kev raws li crosslinks, precision ± 2-5%, qis tshaj tshuaj raug. DSC ntsuas residual tshuaj tiv thaiv tshav kub (α = 1-ΔHresidual / ΔHtotal) - txhim khu kev qha ntawm qis-rau-nrab hloov dua siab tshiab tiam sis overestimates ntawm siab hloov dua siab tshiab vim diffusion-limited residual pawg, repeatability < ± 2%.

PTFE high-temperature npuag yog dav siv nyob rau hauv kev lag luam tshuaj rau xya daim ntaub ntawv tseem ceeb: flange gaskets thiab cov yeeb nkab hauv ob sab phlu (resists muaj zog acids / alkalis), reactor thiab tank linings (tiv thaiv hlau corrosion, yooj yim tu), lim hnab rau corrosive flue gas (txog 260 ° C), anti-corrosion expansion pob qij txha rau ducts, ducts, molding, thiab hluav taws xob / thermal rwb thaiv tsev qhwv. FDA thiab UL qib muaj.

Nto xov cov neeg ua hauj lwm siv rau fiberglass ntaub ua ntej PTFE txheej yog ib qho tseem ceeb rau qhov kawg PTFE high-temperature daim ntaub. Organosilane coupling cov neeg ua haujlwm tsim cov txuas txuas ntawm cov iav fiber ntau thiab cov organic PTFE, txhawb nqa lub zog tev ntawm <2 N / cm rau 4-8 + N / cm. Kev kho kom zoo kuj tseem txhim kho cov cua sov (260 ° C +), dielectric kev ua tau zoo, thiab tshuaj tiv thaiv. Cov ntaub tsis kho ua rau delamination, bubbling, thiab lub neej ua haujlwm luv.
