PTFE tep fil founisè dekri pwodwi yo kòm swa-wo dansite oswa ki ba-dansite. kasèt mas volimik ki wo PTFE fil toujou gen yon dansite nan .70 g / cm3 oswa 1.2 g / cm3. kasèt Low-dansite PTFE fil toujou gen yon dansite nan .37 g / cm3. Rupture fòs se fòs la oblije kraze yon moso nan tep fil pa rale sou fini opoze. Pwolonjman se ogmantasyon nan fraksyon nan longè yon kasèt moso twal kamwazi a akòz estrès nan tansyon oswa nan ekspansyon tèmik. dimansyon enpòtan pou kasèt fil gen ladan longè, lajè, ak epesè. Ak rèspè nan substra konpatibilite, gen kèk kasèt tflon yo fèt pou itilize ak tiyo, tib, oswa kanalizasyon te fè nan aliminyòm, fè nwa, oswa kwiv.

PTFE thread tape suppliers describe their products as either high-density or low-density. High-density PTFE thread tapes usually have a density of .70 g/cm3 or 1.2 g/cm3. Low-density PTFE thread tapes usually have a density of .37 g/cm3. Tensile strength is the force required to break a piece of thread tape by pulling on opposite ends. Elongation is the fractional increase in a thread tape’s length due to stress in tension or to thermal expansion. Important dimensions for thread tapes include length, width, and thickness. With regard to substrate compatibility, some Teflon tapes are designed for use with pipes, tubes, or conduits made of aluminum, black iron, or brass. Other PTFE thread seal tape adheres to chrome, copper, glass, plastic, or rubber.
