CAS nr: 89-32-7 PMDA Pyromellitic dianhydride
Pyromellitic dianhydride (PMDA), cov khoom ntshiab yog dawb orslightly daj crystals. Cov huab cua noo noo yuav sai sai absorbmoisture ntawm huab cua thiab hydrolyzed rau hauv Pyromellitic Acid.Dissolved nyob rau hauv dimethyl sulfoxide, dimethylformamide, acetone thiab lwm yam organic solvents, insoluble nyob rau hauv ether, chloroformand benzene. Feem ntau yog siv los ua cov khoom siv raw rau polyimide, thiab tus neeg sawv cev crosslinking rau kev tsim cov epoxy curing tus neeg saib xyuas thiab polyester resin extinction.
