Core material combination:

Outer plastic:

FEP (Fluorinated Ethylene Propylene): Temperature resistant to -80 ℃~205 ℃, resistant to hydrofluoric acid and concentrated sulfuric acid
PFA (Fusible Polytetrafluoroethylene): Temperature resistance -200 ℃~260 ℃, resistance to aqua regia and organic solvents

Inner rubber:
Fluororubber (FKM): resistant to high temperatures up to 180 ℃, resistant to mineral oil and synthetic hydraulic oil
Silicone rubber (VMQ): resistant to -60 ℃ low temperature, physiologically inert (FDA certified)

Performance breakthrough:

Chemical resistance: According to ASTM D543 standard, it can resist environments with 98% concentrated sulfuric acid, 30% sodium hydroxide, and chlorine gas

Friction coefficient: FEP+fluorine rubber static<0.15, dynamic<0.25 (surface polishing treatment)

Leakage rate: Helium mass spectrometry detection<1 × 10 ⁻⁹ Pa · m ³/s (applicable for vacuum sealing)

Application scenarios: Semiconductor equipment wafer transfer, chemical reactor stirring shaft, pharmaceutical sterile pipeline, deep-sea exploration equipment.
