9,9-Bis (4-hydroxyphenyl) fluoride feem ntau yog siv ua ib qho nruab nrab hauv kev tsim cov organic, thiab kuj siv rau hauv kev tsim cov poly (arylene ether) tshiab. Vim nws cov qauv tshwj xeeb, nws tuaj yeem txhim kho qhov kub tsis kam ntawm cov polymers thiab muaj cov khoom zoo optical thiab formability. Yog li ntawd, nws tau dhau los ua cov khoom siv raw lossis modifier rau kev tsim cov polycarbonate tshiab tiv taus kub, epoxy resin, thiab polyester.
Feem ntau ntim rau hauv 25kg / nruas, thiab kuj tuaj yeem ua pob khoom raws li koj xav tau.
