SEFLOR® C20-M21
COPOLIMERO

Introduction

Seflor® C20-M21 fluoroelastomer is a medium-low viscosity copolymer of hexafluoropropene and vinylidene fluoride particularly suitable for extrusion and compression moulding of sealing devices that must meet the most critical conditions of usage. Seflor® C20-M21 fluoroelastomer offers significant processing ease that can be modified when blended with similar fluoroelastomers. Seflor® C20-M21 is especially suited to curing with bisphenol-phosphonium salt systems.

Provides

  • fast curing rates
  • low mould fouling
  • easy mould release
  • good mould flow
  • improved extrusion
  • good compression set resistance

Application

  • Compression Moulded goods
  • Extruded cords

Safety and Handling

Despite the chemical inertness at ambient temperature, Seflor® C types fluoroelastomers should be handled in such a way to avoid contact with skin and eyes. In case of contact, wash thoroughly with soap and water. Store in a well ventilated place away from any source of heat. Smoking is strictly forbidden in working and storage areas. In the event of fire, toxic gases are produced. Refer to MSDS for additional information. For the safe handling of other compound ingredients normally used in fluoroelastomers compounding, please refer to the respective manufacturers.
