In the biopharmaceutical industry, the safety and stability of the production environment are directly related to the quality of drugs, the life safety of patients and the compliance operation of enterprises. From vaccine development to cell therapy, from antibody drug production to hazardous waste treatment, the requirements for the sealing system in each link are almost harsh – not only to resist the repeated erosion of corrosive disinfectants, but also to maintain airtightness in extreme temperature and humidity environments, but also to prevent biological contamination and rodent invasion.
Faced with this series of challenges, TST seal, as a benchmark enterprise for domestic substitution, deeply integrates the strict military standards with the special needs of the medical industry, and uses innovative technology and customized services to create a set of modular sealing solutions covering all scenarios for the biopharmaceutical industry. Its core technology advantages have been rigorously verified by multiple standards and have become a key force to support industrial upgrading.

Building a “multi-dimensional defense line” for biopharmaceutical sealing
The particularity of the biopharmaceutical production environment determines that the sealing system must meet multiple stringent standards at the same time: it must achieve seamless isolation of physical space and adapt to long-term stability under dynamic conditions. TST seal modular sealing and penetration system builds multiple lines of defense:

Super corrosion resistance, adapting to high-frequency cleaning needs

In order to ensure the sterility of the production environment, biopharmaceutical plants need to frequently use various types of disinfectants for cleaning, which places extremely high demands on the corrosion resistance of sealing materials. The TST seal sealing system uses EPDM rubber, which greatly improves the material’s resistance to chemical corrosion through molecular structure optimization and surface treatment processes. After repeated wiping and soaking with common disinfectants such as sodium hypochlorite and hydrogen peroxide, the sealing material can still maintain good elasticity and sealing performance, without deformation, cracking, or swelling. This feature not only guarantees the service life of the sealing system, but also ensures that the sealing of the production environment is not affected during long-term high-frequency cleaning, reducing the downtime maintenance costs caused by sealing failure for biopharmaceutical companies.

High airtightness and dustproof, strictly abide by the cleanliness standards of biological laboratories

As a key place for biopharmaceutical research and development and production, biological laboratories have extreme requirements for cleanliness. The TST seal sealing system adopts a precise multi-layer sealing structure design to achieve extremely high airtightness and dustproof performance. It can effectively prevent the invasion of outside air, microorganisms, and dust particles, ensuring that the air cleanliness in the laboratory meets strict standards. Whether in the cell culture stage of vaccine development or in the aseptic filling process of antibody drug production, the TST seal sealing system can provide a stable and clean environment for key production operations, effectively ensuring product quality and the reliability of research and development results.

Excellent explosion-proof performance, protecting the safety of hazardous production areas

In hazardous areas such as explosion-proof workshops and hazardous waste treatment stations in the biopharmaceutical industry, the presence of flammable gases and flammable chemicals makes explosion-proof the core requirement of the sealing system. The TST seal sealing system adopts a double explosion-proof structure design for explosion-proof scenarios. The inner layer is made of flame-retardant and antistatic materials, and the outer layer is matched with a high-strength explosion-proof stainless steel shell to form a solid explosion-proof barrier. After strict explosion-proof testing and certification, the TST seal sealing system can meet various explosion-proof level requirements and provide solid guarantees for the safe operation of hazardous production areas of biopharmaceutical companies.
Dynamic environmental adaptability to cope with complex working conditions

In the biopharmaceutical industry, negative pressure workshops and power distribution rooms pose more stringent dynamic environmental challenges to the sealing system. Negative pressure workshops have comprehensive requirements for sealing in order to maintain a stable negative pressure environment and prevent the diffusion of harmful gases and the entry of pollutants; and the vibration of the cables in the distribution room due to the current load can easily cause the seals to loosen and the gaps to expand, which in turn causes the seals to fail. The peelable variable diameter pipe penetration sealing system launched by TST seal has become a “weapon” to deal with such problems. Through the coordinated operation of elastic materials and precision mechanical structures, it can achieve accurate sealing of micron-level gaps. While ensuring the high airtightness of the negative pressure workshop, it effectively solves the sealing risks caused by the vibration of the cables in the distribution room and ensures the stable operation of the sealing system in a complex dynamic environment.

Full-scenario coverage of the biopharmaceutical industry

In core production areas such as vaccines, antibody drugs, blood products, recombinant proteins, and cell and gene therapy, the requirements for sealing systems in complex scenarios have been upgraded from single protection to multi-dimensional comprehensive challenges such as corrosion resistance, fire prevention, airtightness, biological contamination prevention, and vibration resistance. TST seal has rich practical experience and has shown strong advantages in dealing with complex working conditions.

Surgical clean room: Sterile fortress guards life “zero pollution”

In the battlefield of the surgical clean room, which is a race against death, every trace of pollution may become a fatal hidden danger. TST seal MCT penetration sealing system uses military-grade sealing technology to create a watertight “sterile fortress”. Its IP68 protection performance completely blocks the penetration of disinfectants and microorganisms through cable holes. The modular dynamic adaptation design is perfectly compatible with sterilization processes such as hydrogen peroxide and ozone fumigation, achieving “zero leakage” of sterilizers.

Mechatronic control center: explosion-proof and fire-proof “safety center” escorts the lifeline of medical care

As the “power heart” of the hospital, the electromechanical control center will cause the paralysis of all hospital equipment once it is lost. TST seal draws on the explosion-proof and fire-proof technology in the military industry to build a three-in-one protection system. Its special refractory materials have undergone rigorous testing and can successfully block the flame spread path, winning golden time for personnel evacuation and rescue.
In terms of technical foresight, the system reserves expansion channels to avoid secondary construction from damaging the protective structure. Built-in electromagnetic shielding system ensures “zero distortion” of signal transmission of precision equipment such as CT and MRI, and guarantees the accuracy of medical diagnosis.

Smart ward: biosafety protection, creating a rehabilitation space

Smart ward is the core place for patient rehabilitation. TST seal builds a five-dimensional environmental protection system with military-grade protection thinking. Create an ideal rehabilitation environment for patients. In view of biosafety hazards, military-grade sealing structure is used at the cable wall, combined with anti-rodent gnawing, to completely block the invasion path of vectors. At the same time, TST seal is deeply integrated into the entire process of biopharmaceutical production, providing customized services of “zero leakage, zero pollution, and zero interference”.

TST seal creates a benchmark for domestic substitution

Driven by the dual forces of the “Healthy China” strategy and global bio-economic competition, TST seal is using sealing technology as a fulcrum to continuously break through the “stuck neck” technical bottleneck. In the future, as biopharmaceuticals evolve towards personalization and digitalization, TST seal will continue to deepen the integration and innovation of materials science, intelligent sensing and clean energy technology, and create another shining industry business card for China’s smart manufacturing.
