Heat Resistance Oil Resistance Automotive Fluoroelastomer

 Molecular Architecture & Performance Logic

Iyo polymer musana inovakwa kubva  kuvinylidene fluoride (VDF) , hexafluoropropylene (HFP)  uye  tetrafluoroethylene (TFE)  mune chaiyo 40/30/30 reshiyo, ichipa iyo  yepamusoro fluorine yemukati inowanikwa mune yekutengeserana FKM . Iyi dense fluorocarbon matrix inogadzira iyo  yakanyanya-yakaderera pamusoro pesimba inovharira (<18 mN m⁻¹)  inodzinga  asiri polar hydrocarbons , polar ester oiri , uye  ane hukasha anowedzera  semethanol kana biodiesel. Peroxide  -scavenging bisphenol-AF cure system  inobvisa brittle post-cure embrittlement, ichipa  > 20 MPa tensile simba  uye  35 kN m⁻¹ kubvarura simba  kunyangwe mushure  me1,000 h @ 200 °C . Mhedzisiro ndeye komboni  inodarika silicone neHNBR ne3 ×  muhamvuropu imwechete yekupisa uku ichichengetedza  <3% vhoriyamu yakazvimba muIRM903 referensi mafuta..
