Industrial Plastic Liners for Tanks, Chutes, Bunds & Chemical Baths
Industrial Plastic Liners for Tanks, Chutes, Bunds & Chemical Baths
At Poly Synthesis Pty Ltd, we design, fabricate, and install custom plastic liners that protect tanks, chutes, hoppers, and process vessels from corrosion, abrasion, and chemical attack. Using engineering-grade materials such as HDPE, UHMWPE, PP-H, PVDF, and ECTFE, our liners deliver long-term protection and extended service life for equipment operating in Australia’s harshest industrial environments.
Whether you manage a chemical plant, metal-finishing operation, or wastewater facility, our industrial plastic liners are engineered to fit precisely, perform reliably, and reduce your maintenance downtime. From new installations to retrofits, we provide cost-effective, Australian-made containment solutions for industries that demand durability.
Engineered for Long-Term Performance
Across chemical processing, bulk materials handling, wastewater containment, and equipment refurbishment, Poly Synthesis delivers industrial plastic liners that combine engineering precision with proven durability. Our materials—HDPE, UHMWPE, PP-H, PVDF, and ECTFE—cover every performance envelope from abrasion resistance to extreme chemical protection.
All liners are fabricated in Brisbane under strict quality control and installed Australia-wide by experienced polymer technicians. The result is a safer, more reliable, and longer-lasting containment system engineered to perform where conventional materials fail.
Why Choose a Plastic Liner?
Steel tanks and chutes eventually corrode, pit, or degrade under chemical or mechanical stress. A plastic liner forms a continuous, impermeable barrier that resists corrosion, prevents leakage, and protects against abrasion. Unlike coatings or fibreglass layers, polymer liners are thermally welded into one seamless system and can be easily repaired or replaced without dismantling the structure.
Our fabrication process ensures that every liner is dimensionally accurate, chemically resistant, and leak-tight. With over two decades of experience in polymer engineering and plastic welding, we deliver dependable containment performance across the mining, chemical, and wastewater industries.
1. Chemical & Plating Process Tanks
In harsh industrial environments where acids, caustics, and solvents are present daily, standard coatings and metal linings degrade rapidly, leading to costly downtime and contamination risks. Our HDPE, UHMWPE, PVDF, PP-H, and ECTFE liners are engineered specifically for chemical and plating process tanks that demand long-term corrosion resistance and dimensional stability.
These advanced polymers resist oxidising acids, halogens, and solvents. Every liner is CNC-cut for precision, welded using ISO-compliant extrusion and butt-fusion techniques, and installed to provide a seamless, leak-tight finish that restores the full integrity of your containment system.
For chemical manufacturers, electroplating shops, and anodising lines, PVDF liners offer unmatched chemical resistance and smooth surfaces that minimise contamination. PP-H is the reliable choice for dosing and neutralisation tanks, while ECTFE performs in highly corrosive mixed-acid environments. Our liners are engineered to fit exactly within new or existing vessels—extending lifespan, preventing cross-contamination, and ensuring your process equipment meets modern safety and compliance standards.
Each system is supported by detailed fabrication drawings and quality documentation, giving engineers confidence in the liner’s performance under cyclic loading and aggressive thermal conditions.
2. Chutes, Hoppers & Bulk Materials Handling
Continuous impact, abrasion, and material hang-ups can cripple production efficiency in bulk-handling systems. Poly Synthesis produces UHMWPE and HDPE liners designed to protect chutes, hoppers, bins, and feeders from severe wear while improving material flow and throughput.
UHMWPE’s ultra-low coefficient of friction ensures free-flowing discharge of granular and sticky materials such as iron ore, sand, salt, fertiliser, or grain. When combined with precise fitment and smooth-welded seams, these liners prevent bridging, clogging, and excessive vibration loading on your equipment.
Our liners are custom-cut on our 4 × 2 m CNC router and formed to match complex geometries. For extreme-wear zones, we can include replaceable liner panels with mechanical fastening or thermal bonding, allowing for rapid change-outs without dismantling the entire structure. In mining, quarrying, and bulk logistics applications, the result is a durable, self-cleaning interior surface that minimises shutdown frequency, reduces noise, and lowers maintenance overheads.
We also fabricate anti-static and UV-stabilised grades for operations that handle combustible dust or are exposed to outdoor conditions. The outcome is a safer, quieter, and more efficient handling system that performs reliably across countless load cycles.
3. Tank Refurbishment & Retrofitting
When corrosion, pitting, or coating failure compromises your tank’s integrity, a custom plastic liner retrofit is the most efficient path to restoration. Instead of scrapping or replacing an entire vessel, Poly Synthesis can renew it from the inside out.
Our process begins with detailed measurement—either by laser scan or manual templating—followed by CNC-cutting, pre-forming, and welding of the liner panels to fit precisely within the existing tank shell. The liner is mechanically restrained or extrusion-welded in place, creating a new inner wall that resists chemicals, abrasion, and UV degradation.
This approach saves both capital and time: installation can often occur without dismantling external pipework or supports. It is ideal for chemical process tanks, plating baths, water storage, and wastewater systems, allowing a full structural life extension at a fraction of replacement cost.
Every retrofit includes QA documentation, hydrostatic leak testing, and optional maintenance inspections to verify long-term performance. Customers benefit from a rapid turnaround, reduced downtime, and a solution that transforms ageing assets into reliable, high-performance infrastructure.
4. Wastewater, Effluent & Bund Containment Systems
Containment integrity is non-negotiable when managing liquids, sludge, or chemicals that threaten environmental safety. Our HDPE and PP-H liners deliver exceptional performance in wastewater treatment tanks, effluent ponds, and bund containment systems, creating long-term protection against corrosion, leaks, and seepage.
Each liner is pre-fabricated to site dimensions, transported in manageable sections, and field-welded into a monolithic, watertight membrane. The materials are UV-stabilised for outdoor use and resistant to a wide pH range, making them ideal for treatment plants, chemical depots, and industrial wash-down facilities.
For secondary containment bunds, we provide liners that comply with EPA and WHS regulations, forming a permanent chemical barrier under storage tanks and drums. Our installers conduct vacuum testing of welds and visual QA checks to ensure every seam meets stringent containment criteria.
Beyond compliance, these liners provide operational confidence—protecting personnel, preventing costly clean-ups, and supporting environmental sustainability targets. The result is a fully engineered containment system built to safeguard your facility for decades of service.

Case Study: Custom Plastic Sheet Fabrication for Chemical Processing Plant
Client: A leading chemical processing facility in New South Wales
Project: Fabrication of custom plastic containment barriers and chemical-resistant panels
Challenge:
The client required custom plastic panels and barriers to contain chemical spills and protect sensitive machinery in a high-risk processing environment. The material needed to be chemically resistant to a wide range of hazardous substances, while also being durable enough to withstand continuous exposure to harsh industrial conditions.
Solution:
We worked with the client to fabricate custom panels using PVC-U, chosen for its excellent chemical resistance and durability. Our team employed CNC machining to ensure precise cuts and shapes, creating panels that fit perfectly within the processing plant’s containment zones.
To further enhance the panels’ resistance to chemical spills and corrosion, we applied additional surface treatments to extend their lifespan in such a harsh environment.
Result:
The custom-fabricated panels provided the plant with robust containment solutions, ensuring both worker safety and protection of equipment from potential chemical exposure. The project was completed on time, and the client reported significant improvements in safety and operational efficiency.
