Xihloko lexi xi pimanisa ku pakanisa ka tindlela tinharhu to kambela digri ya ku horisa eka swinamarheti leswi twaka ntshikelelo wa silicone. Ku humesiwa ka solvent (gel content) swi pima xiphemu xa network lexi nga nyawuriki hiku tirhisa Soxhlet extraction — ku ringanyeta ngopfu hikokwalaho ka swiphemu leswi pfanganisiweke hi nyama leswi endliweke xihoxo tani hi crosslinks, precision ±2-5%, ku pakanisa ka tikhemikhali tale hansi swinene. DSC yi pima ku hisa ka residual reaction (α=1-ΔHresidual/ΔHtotal) — ku tshembheka eka ku hundzuka ka le hansi ku ya eka ka le xikarhi kambe yi ringanyeta ngopfu eka ku hundzuka ka le henhla hikwalaho ka mintlawa ya masalela leyi nga na swipimelo swa ku hangalaka, ku phindha-phindha <±2%.

Lapi ra mahiselo yale henhla ra PTFE ritirhisiwa ngopfu eka indasitiri ya tikhemikhali eka switirhisiwa swa nkoka swa nkombo: ti flange gaskets nati pipe linings (yi lwisana na ti acids/alkalis to tiya), ti reactor na ti tank linings (yi sivela ku bola ka nsimbi, ku basisiwa hiku olova), ti filter bags ta corrosive flue gas (kufika eka 260°C), ti anti-corrosion expansion joints ta ti ducts, anti-adhesion ti pads to welda, lapi ro humesa ra composite molding, na swifunengeto swo pfalela gezi/ku hisa. Tigredi ta FDA na UL ta kumeka.

Switirhisiwa swo hetisa ehenhla leswi cheriweke eka lapi ra fiberglass loko kungase peta PTFE swina nkoka swinene eka matirhelo yohetelela ya lapi ra mahiselo yale henhla ya PTFE. Ti organosilane coupling agents ti endla mabuloho ya molecular exikarhi ka inorganic glass fibre na organic PTFE, leswi tlakusaka matimba ya peel kusuka eka <2 N/cm kuya eka 4-8+ N/cm. Vutshunguri lebyi faneleke byi tlhela byi antswisa ku tiya ka kuhisa (260°C+), matirhelo ya dielectric, na ku tiya ka tikhemikhali. Lapi leri nga tshunguriwangiki ri yisa eka delamination, bubbling, na vutomi byo koma bya ntirho.
