ROTOLINING
Seamless Protection Through Advanced Polymer Bonding
Rotolining (rotational lining) is an advanced polymer coating process that creates a seamless, bonded internal layer within metal components. This process involves the precise heating and rotation of a part while a thermoplastic powder melts and fuses to its inner surfaces, forming a continuous corrosion and chemical resistant barrier.
At Matrix, we use rotolining to extend the service life of components exposed to aggressive chemicals, abrasive media, or subsea environments. Applied in-house by experienced technicians, our rotolining capability ensures durable, high-integrity internal protection across a range of geometries
Rotolining creates a seamless internal polymer lining, delivering long-term protection against chemical, abrasive and thermal degradation – without welds, joints or weak points.
KEY BENEFITS
Seamless, Stress-free Lining
No joints, welds or seams eliminates weak points and reduces failure risk.
Exception Corrosion Resistance
Protects against acids, alkalis, solvents, and aggressive chemicals.
Enhanced Durability
Strong polymer-to-substrate adhesion minimises risk of delamination and maintains vacuum stability.

Enhanced Durability
Strong polymer-to-substrate adhesion minimises risk of delamination and maintains vacuum stability.
Temperature Versatility
Suitable for use up to 150°C depending on polymer type (LLDPE, HDPE, PVDF, ETFE).
Efficient Application for Complex Geometries
Ideal for elbows, spools, vessels, and other intricate internal shapes.
Low Friction and Wear
Uniform surface reduces drag and improves abrasion performance in slurry and fluid transport systems.
APPLICATIONS
Rotolining is ideal for industries that require robust internal protection against corrosion, abrasion, and chemical attack, including:
- Tanks, pipes and spools handling aggressive acids, alkalis and solvents.
- Vessels and pipework exposed to harsh or variable water chemistries.
- Mining and slurry transport systems operating in abrasive or high-solids environments.
- Pipelines, containment systems and process equipment requiring hydrocarbon and chemical resistance.
- Subsea and offshore structures requiring long-term protection from chemical and seawater ingress.
- High-pressure or high temperature vessels requiring seamless, bonded internal linings.
