Production Technology and Quality Control of Medical Silicone Tubing

Medical silicone tube, as an important medical consumable, has been widely used in medical devices, drug delivery systems, and laboratory equipment due to its excellent biocompatibility, chemical stability, and temperature resistance. This article will delve into the production technology and quality control of medical silicone tubing, with a focus on Rixiang Company's technological advantages and market position.

I. Production Technology of Medical Silicone Tubing

1. Selection of Raw Materials

The production of medical silicone tube relies heavily on high-quality silicone raw materials. The main components of silicone are silica (SiO₂) and organic cross-linking agents, whose performance depends on the purity and proportion of the raw materials. High-quality silicone raw materials typically exhibit the following characteristics:

• High Purity: Ensuring the material is non-toxic and harmless, meeting medical-grade standards.
• Fineness: The fineness of silicone particles directly affects the uniformity and performance of the product, usually requiring a fineness of over 1000 mesh.
• Biocompatibility: The silicone material must pass international standards for biocompatibility testing, including cytotoxicity, sensitization, skin irritation, and hemocompatibility.

2. Production Process

The production process of medical silicone tubing involves several key steps:

• Extrusion Molding: Using advanced mechanical extrusion equipment, the silicone raw material is formed into the desired shape and size of tubing. This process requires precise control of temperature and pressure to ensure uniformity and consistency of the product.
• Vulcanization Treatment: Silicone undergoes a reaction with vulcanizing agents at high temperatures to form a stable cross-linked structure, thereby imparting excellent temperature resistance and mechanical strength to the material.
• Post-Processing: This includes cleaning, sterilization, and packaging steps to ensure the product meets sterile requirements.

3. Special Processes and Technological Innovations

To meet the demands of high-end medical applications, some medical silicone tubing utilizes special processes:

• Transparency Control: By adjusting the formula and process parameters, highly transparent silicone tubing can be produced, facilitating medical observation.
• Ultra-Thin Wall Design: Rixiang Company employs advanced extrusion technology to reduce the inner diameter to a minimum of 0.4mm, satisfying the needs of minimally invasive surgery and precision medical devices.
• Rapid Vulcanization Technology: Through optimization of vulcanizing agent formulas and process conditions, Rixiang Company significantly improves production efficiency while maintaining product quality.

II. Quality Control System

1. International Certifications and Standards

The quality control of medical silicone hose must comply with international standards and certifications, including:

• European Union ROHS Certification: Ensuring the material contains no harmful substances.
• U.S. Food and Drug Administration (FDA) Certification: Meeting the production standards for medical devices.
• LFGB Testing: A mandatory certification for food-grade and medical-grade silicone tubing in Germany.
• Chinese National Standards: Adhering to the quality requirements of the domestic medical device industry.

2. Biocompatibility Testing

Rixiang Company strictly follows international standards for biocompatibility testing, including:

• Cytotoxicity Testing: Assessing the toxic effects of silicone on cells.
• Sensitization Testing: Ensuring the material does not induce allergic reactions.
• Skin Irritation Testing: Verifying the safety of the material on human skin.
• Hemocompatibility Testing: Evaluating the compatibility of silicone with human blood.

3. Quality Inspection and Traceability

Rixiang Company has established a comprehensive quality inspection system, covering every stage from raw material procurement to finished product dispatch. Through advanced detection equipment and technology, the company ensures that each batch of product meets quality standards. Additionally, the company employs an information management system to achieve full traceability of product quality, ensuring customer satisfaction and trust.
