Anping County Boli Hardware Wiremesh Products Factory has been a trusted manufacturer of industrial protective solutions since 1998. Our 6mm thick polyethylene sheet is specifically engineered as a protective liner for chemical storage tanks, offering reliable corrosion resistance and long-term durability. With an annual export value of US$5–10 million and shipments to global markets including North America, Europe, and Southeast Asia, we deliver products that meet rigorous international standards. This liner is your cost-effective solution to extend tank lifespan and prevent hazardous leaks.
Manufactured from high-density polyethylene (HDPE) with optional low-density variants, our 6mm sheet provides a robust barrier against a wide range of chemicals, including strong acids, bases, and organic solvents. The material is non-stick, easy to clean, and resistant to impact and abrasion, making it ideal for both new installations and retrofitting existing tanks. Below are the key specifications and features:
| Property | Specification | Benefit |
| Thickness | 6 mm (0.236 in) | Adequate stiffness and puncture resistance |
| Density | 0.94–0.96 g/cm³ | High strength-to-weight ratio |
| Chemical Resistance | Excellent (pH 1–14) | Suitable for most corrosive liquids |
| Temperature Range | -40°C to +80°C | Operates in extreme environments |
| Custom Sizes | Width: 1000–2000 mm; Length: 2000–6000 mm | Reduces seams and installation time |
Product Features:
- Chemical inertness – No reaction with stored chemicals, preventing contamination and degradation.
- UV resistance – Stabilized additives protect against sunlight when used in outdoor tanks.
- Impact strength – Withstands mechanical stress during filling, cleaning, and maintenance.
- Low friction surface – Reduces material buildup and facilitates easy cleaning.
- Flexible yet rigid – Easily conforms to curved tank walls while maintaining structural integrity.
- Weldable edges – Can be heat-seamed for seamless large-area coverage (optional).

Frequently Asked Questions (FAQ):
-
Q: Can this polyethylene sheet be used for food-grade storage?
A: Our standard sheet is industrial grade. For food contact, we recommend a specialized FDA-grade HDPE sheet (available upon request). -
Q: How do I install the liner in an existing tank?
A: The sheet can be cut to size and attached using stainless steel fasteners, adhesive, or a clamping system. We provide installation guidelines with each order. -
Q: Is the 6mm thickness sufficient for concentrated sulfuric acid?
A: Yes, 6mm HDPE is chemically resistant to sulfuric acid up to 80% concentration at ambient temperature. For higher concentrations or elevated temperatures, thicker liners may be recommended. -
Q: What is the maximum sheet size you can produce?
A: Standard maximum width is 2 meters, and length up to 6 meters. Larger sizes can be custom-ordered with lead time. -
Q: Do you offer color options for easy identification?
A: Yes, we offer black (standard), white, blue, and yellow. Custom colors are available for MOQ orders. -
Q: How does the liner handle thermal expansion?
A: HDPE has a coefficient of thermal expansion of about 1.5×10⁻⁴ /°C. We recommend leaving small expansion gaps or using welded seams to accommodate changes. -
Q: Can I get a sample before bulk order?
A: Absolutely. We provide free A4-size samples (shipping cost covered by buyer) for testing. -
Q: What is the lead time for a standard order?
A: Typical lead time is 15–20 working days after deposit, depending on quantity and customization.
