PTFE high-temperature fabric (PTFE-coated fiberglass) hian a normal operating range -70°C atanga 260°C chhungah thermal shock resistance tha tak a nei a. Temperature cycling chak tak a tuar thei a, eg, -50°C freezer atanga 260°C hot press-a kal. Premium grade te pawh hi 260°C atanga 10°C tuiah a lum nghal vat pawhin an dam khawchhuak thei. Mahse, 300°C aia sang (PTFE’s 327°C melting point hnaih) atanga material shocking chuan cracking leh delamination a thlen nghal ang. Fiberglass substrate hian dimensional stability a pe a; PTFE coating hi a limiting factor a ni.

PTFE high-temperature fabric hi chemical industry-ah hmanraw pawimawh pasarih atan hman a ni nasa hle a, chungte chu flange gasket leh pipe linings (acid/alkali chak tak a do thei), reactor leh tank linings (metal corrosion a veng a, tihfai awlsam), corrosive flue gas dahna tur filter bag (260°C thleng), ducts tan anti-corrosion expansion joint, anti-adhesion welding pads, composite molding atana release cloth, leh electrical/thermal insulation wraps te a awm bawk. FDA leh UL grade a awm bawk.

PTFE high-temperature fabric hi 300°C thleng a stable a, mahse kangmeiah chuan a chhe vek a, gas tha lo tak tak a chhuah chhuak thin: hydrogen fluoride (HF) (corrosive, pulmonary edema) leh perfluoroisobutylene (PFIB) (colorless, odorless, ~10x more toxic than phosgene, no antidote). Tin, carbon monoxide, PFOA residue, leh trace dioxins te pawh a awm bawk. Meikhu mask pangngai hian a hlawk lo va; self-contained breathing apparatus (SCBA) hmang rawh. Symptoms a tlai thei.

PTFE coating hmaa fiberglass fabric-a surface finishing agents hman hi final PTFE high-temperature cloth performance atan a pawimawh hle. Organosilane coupling agents hian inorganic glass fiber leh organic PTFE inkarah molecular bridge a siam a, hei hian peel strength <2 N/cm atanga 4-8+ N/cm thlengin a tipung a ni. Treatment dik tak hian heat resistance (260°C+), dielectric performance, leh chemical resistance a tichak bawk. Fabric enkawl loh hian delamination, bubbling, leh service life tawi a thlen thin.
