Product Introductio
Enhanced Properties
- Extreme Endurance: 1.0% evaporation loss at 200°C/24h (MIL-S-8660), 3.0% after 1000h.
- Load-Carrying Capacity: >4,900 N weld load (ASTM D2596), 1.3 mm wear scar (ASTM D2266).
- Low-Temperature Limit: Torque unmeasurable at -40°C (JIS K 2220); operational minimum is -20°C.
- Corrosion Safety: Emcor test rating 0-1 (DIN 51802), indicating negligible corrosion.
Application Scenarios
• Semiconductor: Robot arms in vacuum chambers, wafer transfer bearings (low contamination).
• Paper Manufacturing: Dryer roller bearings (resists steam & chemical residues).
• Energy: LNG valve seals (cryogenic -162°C & methane resistance).
• Aerospace: Satellite thruster seals (validated in high vacuum).
Source: DuPont technical bulletins & OEM maintenance guides (e.g., Applied Materials).
