FKM tasnifi Ftor tarkibiga yoki ularning o'zaro bog'lanish mexanizmiga hamda kimyoviy tarkibiga asoslanadi. Kimyoviy moddalar va issiqlikka chidamlilik FKMlarning qo'shimcha xususiyatidir. FKM ishlab chiqaradigan kompaniyalar qatoriga Dyneon Fluoroelastomerlar (3M), HaloPolymer (Elaftor) Solvay Specialty Polymerlar, Daikin Chemical va boshqa Xitoydan ishlab chiqaruvchilar kiradi. Flooroelastomerlarning narxi nitril kauchuk yoki neoprenga qaraganda yuqori.
