ʻO ka pulu poliimide

ʻO ka fiber polyimide, i kapa ʻia ʻo arylimide fiber, e pili ana i ke kaulahao mole i loaʻa i ka fiber arylimide.

ʻO ka ikaika o ka fiber homopexed ether he 4 ~ 5cN / dtex, ʻo ka elongation he 5% ~ 7%, ʻo ka modulus he 10 ~ 12GPa, ʻo ka ikaika paʻa ʻana he 50% ~ 70% ma hope o 100h ma 300℃, ʻo ka palena o ka oxygen index. 44, a maikaʻi ka pale ʻana i ka radiation.Ketone copolymerization fiber he like hollow shaped section, ikaika 3.8cN/dtex, elongation 32%, modulus 35cN/dtex, density 1.41g/cm, shrinkage o ka wai paila a me 250 ℃ emi iho ma mua o 0.5% a me 1%, pakahi.

Hoʻohana ʻia ia no ke kiʻekiʻe wela o ka lepo kānana mea, uila insulation mea, nā ʻano like ʻole o ke kiʻekiʻe kiʻekiʻe a me nā lole pale pale ahi, parachute, honeycomb structure a me ka wela sealing material, composite material reinforcement and anti-radiation material.
