(1) filter tensile strength is high, elongation is small (3%).
(2) filter network elasticity coefficient is high, good rigidity.
(3) The filter elasticity limit internal elongation is large and the tensile strength is high, so the absorption impact energy is large.
(4) Filter for inorganic fiber, with non-flammable, good chemical resistance.
(5) Small water absorption.
(6) High temperature resistance. (7) High filtration efficiency.
