Product Introduction
Black silicone tubing is a flexible, black tubular silicone product manufactured by vulcanizing high-performance silicone through a specialized process. It combines the outstanding properties of silicone with the distinctive aesthetic appeal of its black color, making it widely used in food and medical applications, industrial equipment, electronics and electrical systems, automotive industries, and more.
Core Performance Features
Wide temperature resistance range
Operating temperature: **–40°C to 250°C**; can withstand short-term exposure to 300°C. It remains flexible at low temperatures and retains its shape at high temperatures.
High elasticity and flexibility
Soft texture and excellent resilience; it resists cracking and permanent creasing even after repeated bending and twisting, with strong installation compatibility.
Aging resistance and weather resistance
UV‑resistant, ozone‑resistant, and weather‑proof; suitable for long‑term outdoor use without aging or cracking, ensuring a long service life.
Chemical stability
It is resistant to water, oil, weak acids and weak bases, and most solvents; it is not easily corroded and does not react with the medium.
Electrical insulation property
It exhibits high volume resistivity, excellent insulation performance, and stable dielectric properties under high-temperature and humid conditions.
Health and Safety
Non-toxic, odorless, and tasteless; does not harbor bacteria; can withstand high‑temperature, high‑pressure sterilization; suitable for both food and medical applications.
Exclusive Black-Color Advantages
Stain-resistant, with excellent light-blocking properties and enhanced UV resistance, it is well-suited for light‑shielded conveyance and dark‑colored equipment applications, offering a more discreet and aesthetically pleasing appearance.Main application areas
Food and beverage industry: liquid/gas delivery tubing for coffee machines, water dispensers, beer dispensers, and food-processing equipment; baby bottle straws.
Medical and nursing field: medical drainage tubes, tracheal intubation tubes, tourniquet tubes, and medical device connecting tubes.
Electronics and electrical industry: insulating sheathing tubes for electronic devices, sensor protection tubes, and antistatic conductive silicone tubes.
Automotive Industry: automotive vacuum tubes, heater hoses, wire harness protection conduits, and turbocharger air‑intake ducts.
Aquarium and horticulture: aquarium oxygen tubing, aquarium equipment connector hoses, and horticultural drip irrigation tubing.
Industrial equipment: chemical fluid conveyance, peristaltic pump tubing, sealing sleeves for mechanical equipment, and high-temperature equipment flow‑guiding tubes.Product Specifications
