JINBAO 6mm Rigid PVC Sheets (Type 1 Industrial Grey) are engineered for extreme chemical resistance in water treatment systems. Impervious to acids, alkalis, and salts. High-density solid structure (1.5 g/cm³) ensures leak-proof performance when welded. Ideal for tank construction and linings.
Rigid PVC Sheets
JINBAO
For environmental engineering firms and industrial tank fabricators, Jinan Jinbao Plastic Co., Ltd. provides our Industrial Grade Rigid PVC Sheet (Type 1).
Specifically formulated for water treatment systems, this 6mm solid grey sheet offers the chemical inertness required to handle corrosive wastewater, desalination brines, and chemical dosing. Unlike standard PVC used for signage, JINBAO’s Industrial PVC is a high-density engineering plastic that meets ASTM D1784 standards for structural tank fabrication, ensuring zero leakage and long-term durability in harsh environments.
Superior Chemical Resistance: Excellent resistance to strong acids (sulfuric, hydrochloric), alkalis, and oxidizing agents commonly found in water purification plants.
Weldable Fabrication: Compatible with hot gas welding using PVC rod, allowing for the construction of seamless, leak-proof tanks and flanged connections.
Moisture Impervious: Zero water absorption prevents degradation, swelling, or bacterial growth, meeting requirements for clean water systems.
High Structural Strength: At 6mm thickness, it provides sufficient rigidity for self-supporting tank walls and baffles without reinforcement.
Fire Retardant: Rated UL94 V-0 (Self-Extinguishing), ensuring safety in industrial facilities with strict fire codes.
Electrical Insulation: High dielectric strength makes it suitable for control panel backboards in wet areas.

Water Treatment: Sedimentation tank baffles, clarifier weir plates, and desalination equipment housings.
Chemical Processing: Acid storage tanks, plating baths, and fume scrubber bodies.
Ventilation: Corrosive air ducting and industrial fans (using thinner 3-4mm sheets for forming).
Laboratory: Chemical-resistant bench tops and drip trays.
Leak-Proof Guarantee: Our sheets are extruded using virgin resin to prevent micropores. We also supply color-matched PVC Welding Rods (Grey/White) to ensure your tank welds are as strong as the sheet itself.
Precision Flatness: Our annealed sheets are stress-relieved to stay flat during CNC machining, critical for creating precise flanges and filter plates.
Custom Dimensions: For large tank projects, we can extrude sheets up to 2000mm wide and custom lengths (e.g., 4m or 6m) to reduce the number of welded seams, minimizing potential leak points.
Production Process
Certifications
◇ Certifications that our cast Acrylic sheet obtained: SGS, CE, ISOcertificate.
Q: Can I use this for drinking water tanks?
A: Yes, our virgin rigid PVC is safe for water contact. However, for potable water certification (NSF-61), please specify "Potable Grade" in your inquiry so we provide the correct formulation documentation.
Q: How do I join these sheets?
A: Rigid PVC is best joined by Hot Gas Welding (using a heat gun and PVC rod) for structural tanks. For non-pressure applications, Solvent Cement (PVC Glue) works very well.
Q: Is 6mm thick enough for a 1000L tank?
A: For a tank of that size, 6mm is suitable for liners or small compartments. For the main structural walls of a large self-supporting tank, we typically recommend 10mm to 12mm. Our engineers can assist with thickness calculation.
Q: Does it withstand sunlight?
A: Standard dark grey industrial PVC has good UV resistance. For equipment exposed to direct sunlight in tropical regions, we recommend our UV-Stabilized grade to prevent chalking over time.

Why do acrylic sheets in the same market have such different prices? This side-by-side fire test demonstrates how material quality can affect burning behavior.We first tested two low-priced acrylic sheet samples supplied by our customers and purchased from their local market. During the test, the samples produced heavy black smoke and a strong, unpleasant odor. After burning, their surfaces turned completely black.We then tested Jinbao premium acrylic sheet, manufactured using 100% virgin MMA material. It produced fine white smoke with a slight sweet odor. After the test, the surface showed only slight yellowing and small burn marks.Test observationsLow-price acrylic sheet samples:Heavy black smokeStrong, unpleasant odorSurface turned completely blackJinbao premium acrylic sheet:Made with 100% virgin MMAFine white smokeSlight sweet odorOnly slight yellowing and small burn marksStable and consistent qualityThis comparison helps illustrate the difference between different acrylic sheet quality grades—and why prices can vary significantly within the same market.Jinbao Acrylic Sheets — 100% virgin material, stable quality, and reliable performance.Contact us for product specifications, samples, quotations, or customized acrylic sheet solutions.
