What is platinum-cured silicone rubber, and why is it preferred for medical applications? +Platinum-cured silicone rubber uses a platinum catalyst during the vulcanization process, resulting in an extremely pure material with no by-products. This makes it highly biocompatible, non-toxic, and compliant with ISO13485 medical device standards. It does not cause cytotoxicity, sensitization, or irritation, making it the preferred choice for tubing used in medical devices, pharmaceutical equipment, and food contact applications.
-
What temperature range can this silicone tubing withstand? +This silicone tubing operates stably from -60℃ to 220℃ (with standard use range of -50℃ to +200℃). It maintains its flexibility, transparency, and mechanical properties across this wide temperature range, making it suitable for both cryogenic and high-temperature industrial and medical environments.
-
What sterilization methods are compatible with this silicone tubing? +The tubing supports multiple sterilization methods including autoclaving (steam sterilization at high pressure and temperature), gamma irradiation, and ethylene oxide (EtO) sterilization. It can also be cleaned with water, isopropyl alcohol, or medical-grade detergents without degrading the material's properties.
-
Can the silicone tubing be customized in size or color? +Yes. The standard color is high transparency, but custom colors are available upon request. Inner diameter and wall thickness can be customized per customer drawings, covering a wide range from small micro-bore sizes (Φ0.4mm) to large bore sizes (Φ75mm+). Various hardness grades from 40A to 70A Shore A are also available.
-
How should the silicone tubing be stored to maintain its performance? +Store the tubing in a cool, dry, and well-ventilated environment away from direct sunlight, heat sources, and sharp objects. Avoid contact with strong acids, alkalis, or organic solvents during storage. Proper storage conditions help preserve the tubing's transparency, flexibility, and mechanical integrity over time.
-
Is this silicone tubing suitable for use with chemicals and pharmaceutical fluids? +Yes. The tubing demonstrates excellent chemical resistance against a wide range of bodily fluids, pharmaceutical solutions, and common disinfectants. However, it is recommended to conduct compatibility testing before use with strong acids, strong alkalis, or specific solvents to ensure full suitability for your application. Its stable electrical insulation properties also make it suitable for use in electrical and electronic environments.
