如何選擇氟彈性體?

氟彈性體可按以下方式劃分。

A.治療系統
B. Monomers
C.應用程序

對固化系統來說,一般有兩種方法:雙酚固化 FKM 以及過氧化氫可固化的FKM�？晒袒疐KM通常具有低壓縮集的特點,用于成型密封件如奧林、墊圈、不規則環、型材等�？晒袒�過氧化氫FKM具有較好的抗化學性和機械性能。它對蒸汽有很大的抵抗力.它可以用于智能可穿戴或鋰電池。

對單體而言,共聚物是由偏氟乙烯(Vdf)和六氟丙烯(HFP)制成的;三元聚合物是由偏氟乙烯(Vdf)、四氟乙烯(TFE)和六氟丙烯(HFP)制成的。FKM共聚物含氟量為66%,可廣泛應用。FKM三元聚合物含氟量約為68%,可在惡劣環境中使用,需要較好的耐化學/介質性。

應用方面,富迪供應成型,日歷,擠出等級FKM。此外,我們還提供特殊的產品,如低溫耐熱性、高含氟量、70%含氟量、水蒸氣耐堿性、高耐化學性、全氟彈性體的FFKM等。

How to choose fluoroelastomer?

Fluoroelastomer can be divided in following ways.

A. Curing system
B. Monomers
C. Applications

For curing system, there are general two ways: Bisphenol curable fkm and peroxide curable fkm. Bishpenol curable fkm usually owns the features of low compression set, which is used for molding sealing parts like orings, gaskets, irregular rings, profiles. And Peroxide curable fkm has better chemical resistance and mechanical properties. It has great resistance to steam. It can be used in smart wearables or Lithium battery.

For monomers, there are copolymer which is made by Vinylidene fluoride (VDF) and hexafluoropropylene (HFP); and terpolymer which is made by Vinylidene fluoride (VDF), tetrafluoroethylene (TFE) and hexafluoropropylene (HFP). FKM copolymer has 66% fluorine content can be used in general application. While fkm terpolymer has fluorine content about 68%, it can be used in harsh environment which requires better chemical/ media resistance.

For applications, FUDI supply molding, calendaring, extrusion grades fkm. And we also supply special grades like low temperature resistance grade GLT, high fluorine content with fluorine content 70%, steam and alkali resistance grade FEPM Aflas, excellent chemical resistance grade perfluoroelastomer ffkm.
