In recent years, driven by the rapid advancement of precision medicine, implantable medical technologies, and other high-end healthcare fields, medical-grade platinum-cured silicone—with its exceptional biocompatibility, stability, and process adaptability—has successfully unlocked new high-end medical scenarios, including implantable devices, surgical robotics components, and biopharmaceutical applications. It has become a critical material supporting medical technology innovation and driving high-quality development in China's advanced healthcare sector.

High-end medical applications impose extremely stringent requirements on material safety and performance—requirements that medical-grade platinum-cured silicone precisely fulfills. Through the platinum-catalyzed curing process, this material achieves zero heavy metal residues and extremely low extractable levels, allowing direct contact with human blood and tissues without triggering immune responses, making it suitable for long-term implantation. With an elongation at break of 500%–800%, it recovers rapidly after deformation and offers outstanding resistance to radiation and aging, meeting the durability demands of advanced medical devices.

In the field of implantable medical devices, platinum-cured silicone has become one of the core materials. Products such as cochlear implant housings, orthopedic implant seals, and long-term implantable catheters are manufactured using this material. High-end biomedical-grade liquid silicone rubbers like DuPont™ Liveo™, produced via platinum-catalyzed processes, are suitable for medical devices intended for implantation exceeding 30 days. Their strictly controlled tensile and tear strengths provide robust safety assurance for implantable devices, helping numerous patients restore physiological functions.

Significant breakthroughs have also been achieved in surgical robotics and precision medicine. Core components such as fluid transfer tubing for surgical robots and sealing parts for endoscopic instruments are made from platinum-cured silicone. These components feature highly smooth inner walls, preventing residual blood or drug solutions, and withstand repeated sterilization. Their zero-failure operation time exceeds 1,000 hours, effectively enhancing surgical precision and safety. In the biopharmaceutical field, platinum-cured silicone tubing introduced by companies like Bailink complies with multiple international regulatory standards and is applied in vaccine production, monoclonal antibody preparation, and other processes, ensuring cleanliness and safety throughout biopharmaceutical manufacturing.

Notably, the localization of medical-grade platinum-cured silicone in China is accelerating, achieving full autonomy from raw materials to production. Product performance now rivals leading international brands, significantly reducing dependence on imported materials. Industry experts point out that with continuous innovation in material modification technologies, medical-grade platinum-cured silicone will further expand its application boundaries in high-end healthcare, supporting China's medical industry in achieving independent innovation and leapfrog development.
