| JUTAI CT200 Low Temperature Resistant Sealing Ring is a high-performance sealing component made from a specially modified PEEK material known as CT200 (Cold-resistant Thermoplastic 200). It is specifically engineered for extremely low-temperature environments (down to -196°C) and maintains excellent sealing and mechanical properties under harsh conditions such as cryogenic temperatures, high pressure, and chemical exposure. | |||||||||
CT200 Low Temperature Resistant Sealing
The CT200 Cryogenic PEEK Sealing Ring is a high-performance sealing component made from CT200, a specialized low-temperature-resistant polyetheretherketone (PEEK) material. Designed for extreme cryogenic environments (e.g., liquid nitrogen, liquid oxygen, liquid hydrogen), it is widely used in demanding industrial, energy, aerospace, and scientific research applications.
Temperature Range: -196°C (liquid nitrogen) to +250°C, with long-term service stability between -160°C to +230°C
Cryogenic Toughness: Maintains elasticity and flexibility in ultra-low temperatures, preventing brittleness issues common in rubber or PTFE seals
Low Permeability: Exceptionally low gas permeability (H₂, He, N₂), ensuring long-term sealing reliability
Chemical Inertness: Resistant to strong acids, alkalis, organic solvents, and cryogenic media (e.g., liquid oxygen, liquid hydrogen)
Mechanical Strength: High tensile strength (>80 MPa at -100°C) and wear resistance, even in cryogenic conditions
Ultra-Low Temperature Performance: Reliable sealing at -196°C, ideal for LNG, liquid hydrogen, and other extreme conditions
Low Friction & Wear Resistance: Coefficient of friction (0.2–0.3), PV value >3.0 MPa·m/s (at -100°C)
Minimal Cold Flow Deformation: Compression set <15% (ASTM D395)
Extended Service Life: 3–5x longer lifespan compared to PTFE or metal seals
Lightweight: Density of 1.3 g/cm³, making it superior to heavy metal seals for aerospace and precision equipment
Energy Sector: LNG pipeline valves, liquid hydrogen storage tanks, cryogenic pump/valve components
Aerospace: Rocket fuel line seals, cryogenic propulsion systems
Semiconductor Manufacturing: Wafer processing cryogenic traps, superconductor equipment seals
Scientific Research: NMR, particle accelerator cryogenic interfaces
Medical & Biotech: Cryogenic sample storage seals
Parameter Value
Operating Temperature -196°C to +250°C
Tensile Strength (-100°C) ≥85 MPa
Elongation at Break (-196°C) ≥40%
Thermal Conductivity 0.25 W/m·K
Surface Resistivity (ESD Grade Optional) 10⁷–10⁹ Ω/sq (anti-static)
Chemical Resistance Resists acids, alkalis, hydrocarbons, LOX/LH₂
Operating Conditions:
Suitable for static/dynamic sealing (rotary/reciprocating motion)
Recommended max. pressure: ≤20 MPa (custom designs available for higher pressures)
Installation Optimization:
For metal mating parts, maintain a thermal gradient <150K to avoid stress
Plasma surface treatment recommended for enhanced adhesion
Certifications: Complies with ISO 15848, ASTM D7216 for cryogenic sealing performance
The CT200 Cryogenic PEEK Sealing Ring is an advanced solution for extreme low-temperature environments, combining lightweight design, extended durability, and superior sealing performance. It serves as a high-end replacement for traditional PTFE or metal seals in energy, aerospace, semiconductor, and other critical industries. Custom specifications (e.g., dimensions, conductive/insulating grades) are available upon request with detailed operational parameters.
