Material Properties
Ultra-wide temperature range adaptability
• Adopting EPDM/silicone rubber composite formula;
• Working temperature covers -70℃ to +220℃;
• Passed ISO 188 heat aging test (150℃×168h strength retention rate ≥90%);
• Adaptable to cryogenic equipment and high-temperature steam systems.
Chemically inert barrier
• 3-layer co-extrusion structure: inner layer PTFE coating (resistant to strong acids/alkalis/organic solvents), middle layer aramid fiber reinforcement (anti-burst pressure 80bar), outer layer conductive rubber (anti-static accumulation);
• Complies with FDA 21 CFR 177.2600 food grade certification.
Zero permeability and cleanliness
• The molecular-level dense structure makes the gas permeability ≤0.05cc/m²/day (ASTM D1434);
• The inner wall is treated with Electropolish, and the microbial attachment rate is reduced by 98%;
• It meets ISO 13485 medical-grade cleanliness standards.
Dynamic fatigue life
• No cracks after 500,000 pulse pressure tests (0-40MPa cycles);
• Bending fatigue life is 3 times that of DIN 73379 standard;
• Suitable for high dynamic scenarios such as robot hydraulic arms.
Intelligent identification system
• Optional embedded magnetic stripe/fluorescent tracer layer;
• Supports X-ray positioning and AR operation and maintenance guidance to achieve digital management of pipeline systems.
Application Scenarios And Advantages
Medical Equipment
Biocompatible silicone tubes (USP Class VI) are used for hemodialysis and ventilator gas transmission.
01
New Energy Vehicles

03
Semiconductor Manufacturing
Ultra-high purity FEP lined tubes, particle release ≤0.1μm/mL, meet ISO Class 1 clean room requirements.
04
Petroleum Exploration
Aramid reinforced NBR hose, resistant to H2S corrosion + deep sea 3000m pressure resistance, passed API 16C certification.
05
Customized Services
Material Matrix
EPDM (ethylene propylene diene monomer rubber): resistant to ozone/water vapor, suitable for HVAC and food-grade fluids.
FKM (fluororubber): resistant to 300℃ high temperature + strong acid, used in chemical reactors and engine fuel pipes.
Platinum vulcanized silicone: medical grade transparent tube, resistant to gamma ray sterilization and long-term contact with drug solutions.
HNBR (hydrogenated nitrile rubber): resistant to hydrogen sulfide + super wear resistance, suitable for oil field drilling and LNG transportation.
Engineering customization options
Structural design: single-layer/multi-layer composite, corrugated reinforcement, conductive/antistatic layer composite, support ID 0.5mm-300mm customization.
Functional enhancement
Antibacterial coating: antibacterial rate of Escherichia coli/Staphylococcus aureus ≥ 99.9%
Thermal reflective outer layer: reflectivity ≥ 85%, reducing the surface temperature of the pipeline by 20℃
RFID implantation: store pressure/ temperature threshold data to achieve intelligent early warning
