(1) Cov khoom siv kho tshuab: Tensile lub zog tuaj yeem ncav cuag 1000-3000 MPa-ob mus rau peb npaug ntawm cov hlau zoo tib yam-tsis tau qhov ceev tsuas yog nyob ib ncig ntawm 2.5 g / cm³.

(2) Thermal stability: Lub softening point yog kwv yees li 860 degree, thiab lub sij hawm ntev kev pab cuam kub yuav ncav cuag 350-450 degree.

(3) Chemical inertness: Exhibits zoo tsis kam mus rau feem ntau cov organic solvents, raws li zoo raws li tsis muaj zog acids thiab bases.

(4) Hluav taws xob rwb thaiv tsev: Volume resistivity tshaj 10¹⁵ Ω·cm, nrog tsawg-zaus dielectric poob.
