This is a platinum-cured silicone tube made of high-grade imported fumed silica raw material, rapidly vulcanized with two-component (A/B) addition-type vulcanizing agent, assisted by room temperature vulcanizing agent for fast curing. The medical silicone tube is completely non-toxic, odorless and highly transparent, with higher efficiency and no odor compared with traditional peroxide-cured silicone tubes. Produced with specially inspected equipment to meet the highest quality standards, it features an integrated supply chain and complete documentation (from raw material testing during production to final inspection and batch sample retention) to ensure full traceability of raw materials.

Properties of Medical Capillary Silicone Tube

High transparency, high hygiene level, eco-friendly and odorless, autoclavable and sterilizable at high temperature and pressure.

Excellent physiological inertness, harmless to human body, no foreign body reaction or tissue inflammation after implantation.

High tensile strength, excellent tear resistance, low shrinkage and good resilience.

Excellent high and low temperature resistance, no deformation or harmful substance decomposition under high temperature, with outstanding physiological inertness and bio-aging resistance.

High hygiene and environmental protection level, certified by food-grade safety standards such as FDA and LFGB.

Applications

Mainly used in clinical medicine, pharmaceutical fluid guidance, biopharmaceuticals, medical research, medical analytical instruments, ventilators, small household appliances, food and beverage transmission, dairy products, beer, peristaltic pumps, veterinary pharmaceuticals, chemical industry and other industrial fields. Our medical-grade silicone tubes and pharmaceutical-grade silicone tubes belong to the same category of products.

Q: What is capillary silicone tube?
A:
Capillary silicone tube is a high-precision extruded silicone rubber hose with an extremely small inner diameter (usually ≤2mm). It features non-toxic, odorless, high/low temperature resistance, aging resistance and biocompatibility, and is mainly used in scenarios such as precision fluid delivery, medical/laboratory and electronic equipment.

Q: What are the common specifications of capillary silicone tube?
A: The conventional inner diameter is 0.3mm-2mm, wall thickness is 0.1mm-1mm. Common specifications include 0.5×1mm, 0.7×1.3mm, 0.8×1.5mm, etc. Special inner diameter, wall thickness, multi-lumen structure and color (milky white/transparent/colored) can be customized.

Q:Can capillary silicone tube be food grade/medical grade?
A:
Yes. Food-grade capillary silicone tube complies with FDA and LFGB standards, used for food machinery and beverage delivery; Medical-grade capillary silicone tube passes USP Class VI and ISO 10993 biocompatibility certification, suitable for medical equipment, infusion and laboratory supplies. Please select the corresponding grade according to the usage scenario.

Q: Is capillary silicone tube easy to block? How to solve it?
A:
Due to the extremely small inner diameter, it is easy to block when transporting fluid with impurities. Solutions:  Select tubes with high smooth inner wall;  Filter fluid impurities before transportation; Clean the pipeline regularly with special tools;  Select appropriate inner diameter according to working conditions to avoid too small specifications.

Q: What is the impact of uneven wall thickness of capillary silicone tube?
A:
Uneven wall thickness will lead to reduced pressure resistance, unstable fluid delivery, and easy local fracture during bending, which affects the use of precision equipment. Our company adopts high-precision extrusion process and online inspection to strictly control wall thickness tolerance and ensure product consistency.

Q: What is the temperature resistance range of capillary silicone tube?
A:
Ordinary capillary silicone tube has a temperature resistance of -40℃~200℃, and can be used in 180℃ environment for a long time; High temperature resistant modified models can withstand 260℃ high temperature, meeting special working condition requirements.
