Characteristics:
SF-604: Good permeability, good mechanical stability, can be used
repeatedly impregnating sintering, suitable for mixing process.
SF-601: Good stability, general purpose.
SF-604Z: Good permeability, good mechanical stability, can be used
repeatedly impregnating, suitable for mixing process.
SF-631Z: Good gloss and transparency.
SF-651PS: Good metal adhesion, good mechanical stability, highly
compatible with ordinary PTFE dispersion, suitable for mixing
process.
SF-661: Good gloss and transparency, good metal adhesion, good
mechanical stability, highly compatible with ordinary PTFE
dispersion, significantly improve the non-stick effect of the
coating, suitable for mixing process.
