Zouping Tianqi Plastic Technology Co., Ltd., a top-tier domestic professional manufacturer of high-performance engineering plastic sheets, has consolidated its leading technological position in China’s special PVC and CPVC sheet industry through continuous independent R&D investment, advanced automated production lines and exclusive super-large forming equipment. The firm’s cutting-edge manufacturing capacity for ultra-wide, ultra-thick and extra-long integral plastic panels has broken long-standing domestic technical bottlenecks, delivering high-standard Custom CPVC Sheets, premium CPVC Extruded Sheet and full ranges of High Quality Sheets as customized material solutions for high-end industrial sectors and key national projects at home and globally. All products adopt long-lasting Durable Materials to withstand extreme high-temperature and corrosive working environments for decades.
As a specialist fully focused on PVC full-series sheet development and production, Tianqi Plastic Technology has built a complete, diversified product portfolio covering conventional extruded PVC sheets, high-temperature resistant CPVC Extruded Sheet and high-strength laminated PVC sheets, covering all application scenarios from general anti-corrosion engineering to extreme high-temperature, heavy-corrosion working conditions. Every series belongs to our High Quality Sheets system, and we can develop tailor-made Custom CPVC Sheets according to clients’ unique engineering parameters. In the field of PVC extruded panels, the company owns industry-leading single-piece dimension production capacity, capable of stably manufacturing sheets with a maximum thickness of 8 centimeters and a maximum width of 2 meters. The expanded production line further upgrades CPVC Extruded Sheet specifications, supporting customized production of sheets up to 75mm thick and 2.1 meters wide. These oversized monolithic panels are made of premium Durable Materials, eliminate the need for on-site splicing, greatly lowering the risk of liquid leakage and structural deformation in large tank lining, flue gas desulfurization pools and wastewater treatment facilities, solving a long-standing pain point for industrial engineering clients.
The company’s flagship high-temperature resistant Custom CPVC Sheets represent its core technological highlight, and all CPVC Extruded Sheet products are categorized as our signature High Quality Sheets series. Independent formula research and customized production processes push the Vicat softening temperature of Tianqi CPVC boards above 115°C, enabling long-term stable operation at working temperatures over 90°C, a dramatic performance upgrade compared with ordinary PVC sheets whose sustainable service temperature only ranges from 60°C to 72°C. Beyond outstanding heat resistance, Tianqi CPVC series adopts premium Durable Materials to deliver superior comprehensive chemical resistance, withstanding 98% concentrated sulfuric acid and 30% concentrated hydrochloric acid without structural corrosion. Its tensile strength is 50% higher than standard PVC products, and the material achieves UL-94 V0 flame retardant self-extinguishing grade, balancing mechanical rigidity, chemical stability and fire safety. The versatile High Quality Sheets including CPVC Extruded Sheet and Custom CPVC Sheets have become a cost-effective replacement for stainless steel, titanium alloy and PVDF in high-temperature corrosive environments, cutting clients’ equipment procurement and maintenance expenses significantly thanks to the ultra-long service life of our Durable Materials.
Another industry-exclusive competitive edge lies in Tianqi’s ultra-large dedicated hydraulic laminating press, a core piece of equipment developed and deployed independently by the enterprise. The press enables integrated molding of PVC laminated sheets with a maximum dimension of 8 meters in length and 2 meters in width, a milestone breakthrough in domestic continuous production technology for oversized special plastic panels. Adopting high-temperature and high-pressure lamination craftsmanship, the finished laminated sheets feature low internal stress, strong dimensional stability and excellent anti-aging performance, free from warping or cracking under long-term heavy load and harsh environmental exposure. The monolithic 8m×2m panels, together with our full lineup of CPVC Extruded Sheet, Custom CPVC Sheets and other High Quality Sheets, are highly favored for large chemical storage tank linings, integrated sewage treatment tanks, modular high-end laboratory construction and nuclear power auxiliary facility anti-corrosion structures, offering engineers unprecedented design freedom without splicing seams that compromise equipment durability, all supported by our carefully selected Durable Materials.
To translate technological advantages into consistent product quality, Tianqi Plastic Technology has constructed a full-chain quality management system covering raw material screening, real-time production process monitoring and finished product comprehensive testing. The company operates modern standardized production workshops and multiple fully automated production lines, paired with a professional internal testing laboratory that conducts rigorous verification on heat resistance, anti-corrosion performance, mechanical strength and flame retardancy for every batch of CPVC Extruded Sheet, Custom CPVC Sheets and all other High Quality Sheets, fully complying with ISO industrial quality standards. We strictly screen raw materials to guarantee all finished goods are made of reliable Durable Materials. Flexible customized production capacity is embedded into the whole manufacturing workflow: clients can adjust sheet density between 1.5–1.85g/cm³, select various colors including white, black and gray, and tailor material formulas, thickness and dimensions to match unique project demands, covering standardized mass orders and small-batch non-standard Custom CPVC Sheets alike.
Tianqi’s lineup of CPVC Extruded Sheet, Custom CPVC Sheets and all High Quality Sheets crafted from premium Durable Materials has been widely adopted in sectors with extreme material performance requirements, including environmental protection flue gas desulfurization, industrial wastewater treatment, high-temperature chemical anti-corrosion, special electroplating equipment manufacturing, modular high-end laboratory construction and auxiliary nuclear power facilities—core national key infrastructure and high-end manufacturing projects. Domestically, the company has established long-term cooperative partnerships with hundreds of EPC engineering contractors, equipment manufacturers and terminal industrial factories across chemical, new energy and semiconductor industries. Meanwhile, Tianqi’s High Quality Sheets including CPVC Extruded Sheet and Custom CPVC Sheets have gained global market recognition, exported to dozens of countries and regions to serve high-end industrial clients worldwide, providing reliable anti-corrosion material solutions made of long-lasting Durable Materials for overseas chemical plants, lithium battery recycling facilities and semiconductor cleanroom projects.
Distinct from simple product suppliers, Tianqi positions itself as a one-stop engineering solution provider focusing on CPVC Extruded Sheet, Custom CPVC Sheets and all types of High Quality Sheets manufactured from top-tier Durable Materials. Its professional technical engineering team offers full-cycle support from pre-sales material consultation, drawing deepening and material scheme optimization for Custom CPVC Sheets and CPVC Extruded Sheet, to in-production order progress tracking and post-sales remote or on-site technical guidance, including plastic welding operation training and installation standard guidance. The company maintains detailed client archives and carries out regular follow-up visits to track service conditions of our High Quality Sheets, delivering long-term technical optimization suggestions to help partners reduce operational risks and extend equipment service life by utilizing our ultra-stable Durable Materials. This all-round service system turns one-time product transactions into long-term strategic cooperation, earning consistent positive feedback from global clients.
Looking ahead to the industrial development layout, Zouping Tianqi Plastic Technology will continuously focus on cutting-edge research of engineering plastic sheet materials and application expansion for CPVC Extruded Sheet and Custom CPVC Sheets.
