In the field of industrial sealing, the penetration sealing system is not only the “guardian” of equipment safety, but also the key to ensuring production efficiency and environmental safety. Swedish company Roxtec occupies an important position in the global market with its innovative modular penetration sealing technology, while the domestic penetration sealing system brand TST seal has performed well in technological breakthroughs and domestic substitution in recent years. This article will analyze in depth how TST seal compares with the international giant Roxtec from the dimensions of materials, processes, application fields and certification standards, and show the rise of domestic sealing technology.

Material performance

Double breakthrough in environmental protection and protection

TST seal and Roxtec both emphasize environmental protection and high performance in the selection of sealing materials, but each has its own technical characteristics. Roxtec’s sealing performance reaches high standards such as IP 66/67 and IP 69K, ensuring stable operation under various conditions.

TST seal has set industry-leading and extremely high standards in terms of sealing technology, fire resistance, corrosion resistance, electromagnetic compatibility and environmental protection performance. Its sealing system uses non-toxic and halogen-free materials, complies with the EU RoHS 2.0 standard, and avoids the release of harmful substances. In terms of fire resistance, the product reaches A-0 to A-60 grades, meets the “2010 International Fire Test Procedure Application Rules” (FTP Rules) and GB23864 standards, and can withstand flame burning for up to 3 hours. In terms of sealing performance, the TST seal system is watertight and airtight, which can meet the pressure sealing of different levels of 0.3 MPa~0.5MPa, and has passed the corrosion resistance test (such as ISO12944 C5-M marine corrosion environment), showing stable performance in extreme environments. It is worth mentioning that the TST seal material design takes into account electromagnetic compatibility, and the shielding effectiveness reaches 42~63dB, which meets the GB/T12190-2006 standard, providing anti-interference protection for military industry, power industry and other industries.

Process technology

The “wisdom” of modular design

Roxtec’s sealing system uses Multidiameter™ technology, based on a sealing module with a peelable core layer, which adapts to cables of different sizes through elastic materials, taking into account flexibility and sealing. Modular stripping layer technology allows flexible adjustment of cable size on site, reducing installation and maintenance costs.

TST seal also uses variable diameter tearable technology. Through the process route of “modular + redundant design”, similar to the assembly method of “building blocks”, it can quickly respond to the needs of increasing, decreasing or replacing cables. For example, in the field of ships, TST seal’s modular cable sealing system supports non-destructive disassembly and assembly, avoiding the disadvantages of traditional sealing methods that damage the structure. The redundant design allows cable channels to be reserved for future expansion. In terms of process details, TST seal products pass vibration and impact tests (such as IEC61373) to ensure long-term stability in high-frequency vibration scenarios such as offshore and rail transit. In addition, in response to the needs of domestic enterprises, TST seal provides localized customization services to shorten delivery cycles and reduce maintenance costs.

Application areas

Differentiated competition for scenario adaptation

Roxtec has been deeply involved in the Chinese market and focuses on providing customized and efficient sealing solutions for the offshore wind power industry. In recent years, Roxtec has demonstrated extraordinary innovation strength and strategic layout in the cutting-edge field of deep-sea and offshore wind power.

As a pioneer in the field of power and rail transit, TST seal has always led the industry change with technological innovation. In the field of power, its penetration sealing solutions have deeply served core institutions such as the State Grid and China Southern Power Grid, covering key scenarios such as high-voltage cable wall protection and electromagnetic compatibility transformation of energy storage power stations, ensuring the safety of power transmission and compatibility with the electromagnetic environment with high-efficiency performance. In rail transit, the company’s core module products have successfully enabled benchmarking companies such as CRRC, Shenzhen Metro, Nanjing Metro, and Guiyang Metro with their technological leadership and stable reliability, building a solid barrier for the safe operation of rail transit. In the shipbuilding industry, the penetration sealing system has obtained authoritative certification from international classification societies such as China Classification Society CCS and Norway DNV, achieving a breakthrough in domestic substitution for imports, and is widely used in well-known companies such as Wison Group and Mingyang Electric, demonstrating its global competitive technical strength and quality standards.

Certification and Standards

International Benchmarking and Domestic Compliance

Roxtec’s global competitiveness stems from its many international certifications, including IMO A-level fire protection, EN45545 fire protection, IEC explosion-proof standards, etc., and its products meet the strict global industry specifications.

TST seal has built a certification system of “international benchmarking + domestic adaptation”. In addition to meeting international standards such as ISO and IEC, its products have passed domestic authoritative tests such as GB/T and FTP rules, such as A-60 fire resistance and IP68 protection level, which meet the A-class separation requirements of China Classification Society. In terms of electromagnetic compatibility, the TST seal system has passed the GB/T12190 broadband test, filling the technical gap of domestic sealing systems in the field of anti-interference. In addition, TST seal’s halogen-free materials comply with EU environmental protection directives, providing compliance guarantees for export projects.

Cost-effectiveness and market prospects

Competitiveness of domestic substitution

Although Roxtec’s technology is leading, its import price and long-term service costs put pressure on domestic small and medium-sized enterprises. In contrast, TST seal takes “performance benchmarking and cost optimization” as its core strategy, significantly reducing procurement and maintenance costs while maintaining its technological advantages. For example, in the field of ship modular sealing systems, TST seal product prices are more than 30% lower than imported brands, and provide localized after-sales response to reduce the risk of customers relying on overseas services. This strategy not only improves the cost-effectiveness of products, but also enhances market competitiveness.

With the advancement of national strategies such as green energy and intelligent manufacturing, TST seal, as a leading brand for localization, has continued to increase its penetration rate in offshore ships, petrochemicals, electric power, nuclear industry and other fields, and the trend of domestic substitution is obvious. TST seal has greatly reduced procurement costs. Relying on a strong raw material supply chain system and the protection of military technology and R&D teams, the quality control quality and product technology have reached a new level of domestic production. At the same time, TST seal provides customized solutions and all-round and flexible implementation plans for various industries, providing more choices for owners, EPCs, design institutes, and construction units, and further expanding market prospects. Through continuous technological innovation and cost optimization, TST seal not only meets the needs of the domestic market, but also shows strong competitive potential in the international market, demonstrating the strong competitiveness and broad market prospects of domestic substitution.

Conclusion
