In heavily corrosive working scenarios such as chemical engineering, new energy and metallurgy, equipment corrosion failure has long been a core pain point affecting production safety and operational costs. According to the 2025 Research Report on Corrosion Status of Chemical Equipment, 82% of domestic chemical enterprises suffer from corrosion and failure of facilities including heat exchange equipment and storage tanks. Safety incidents caused by corrosion leakage account for 18% of all safety accidents in the chemical industry.
As one of the earliest domestic enterprises to conduct applied research on glass fiber backed fluoroplastic sheets, RANA has developed a mature fluoropolymer PTFE, Modified PTFE, PFA, ECTFE, PVDF anti-corrosion lining system through 30 years of technological iteration, delivering reliable solutions for heavy corrosive conditions across multiple industries.
Conventional pure PTFE sheets are plagued by cold flow deformation and insufficient bonding strength, prone to wrinkling, peeling and other failures under high-temperature and high-pressure conditions.Developed by RANA, the glass fiber backed fluoroplastic PTFE, Modified PTFE, PFA, ECTFE, PVDF sheet technology perfectly addresses this industry bottleneck by compounding a special glass fiber reinforced layer on the back of PTFE sheets:
· 40% higher structural strength: The glass fiber reinforced layer effectively restrains cold flow deformation of fluoroplastic materials, with creep resistance at high temperatures reaching 2.3 times that of pure PTFE sheets.
· Bonding strength up to 7.8kN/m: Exclusive interface treatment technology enables far stronger adhesion between sheets and metal substrates compared with sodium etched PTFE panels.
· Superior construction adaptability: Improved flexibility enables fitting inner walls of vessels in various shapes, reducing construction difficulty by 30% and greatly shortening project lead time.
With 30 years of technological accumulation, RANA’s glass fiber backed fluoroplastic lining sheet technology has been widely adopted in diverse industries, with thousands of successful project references:
Leading lithium battery cathode material manufacturers face harsh operating conditions of strong acid, high temperature and severe abrasion in reactor operation. Traditional enamel linings only last an average of 8 months.We delivered a customized anti-corrosion solution with glass fiber backed fluorine resin PTFE GBK sheet, Modified PTFE GBK shee, PFA, ECTFE, PVDF sheets. Optimized material formulation and construction processes extend the service life of anti-corrosion linings to over 5 years, saving the client nearly 3 million USD annually on equipment replacement and production shutdown losses. By the end of 2025, we had provided reactor anti-corrosion services for 32 domestic lithium battery enterprises, ranking among the top players in the market.
A large-scale chemical enterprise in Shandong originally adopted rubber lining for 10 sets of 5,000 m³ concentrated hydrochloric acid storage tanks, which suffered aging and cracking within an average service cycle of 2 years.We renovated the tank linings with glass fiber backed fluoroplastic sheets. The proprietary hot-air welding process achieves zero-leakage weld joints. The facilities have operated stably for 6 consecutive years with an intact lining rate of 99.8%, projected to cut full-lifecycle operation and maintenance costs by over 4 million USD.
Copper smelting enterprises in Jiangxi operate pickling tanks under extreme corrosive environments: 120℃ high temperature, 30% sulfuric acid and chloride ions. Traditional granite linings suffered severe leakage.Our composite anti-corrosion solution — glass fiber backed fluoroplastic sheet + special anti-seepage layer — effectively solves corrosion challenges under high-temperature and strong acid conditions. The system has run steadily for 4 years with zero leakage, earning high recognition from the client.
In the future, RANA will continue to increase R&D investment in glass fiber backed fluoroplastic sheet technology. Focused research on material modification will target extreme working conditions such as ultra-high temperature, heavy abrasion and deep low temperature. Meanwhile, we will integrate IoT technology to develop intelligent anti-corrosion linings with built-in sensors, enabling real-time corrosion monitoring and delivering smarter, more dependable anti-corrosion solutions.
With 30 years of dedication to fluoroplastic anti-corrosion applications, RANA consistently drives industrial progress through technological innovation, eliminating heavy corrosion as a bottleneck for production safety.
