Rotolining is the process of internally coating a metal part with plastic.
Mild steel, stainless steel and aluminium can all be rotolined.

We can use a variety of materials to line, but PE is the most common as it provides good performance in corrosion and wear resistance, is readily available, relatively straightforward to process, has well understood properties and good pricing.

Other lining materials include from the fluoropolymer families including ECTFE (ethylene-chlorotrifluoroethylene) is an alternating copolymer of ethylene and chlorotrifluoroethylene.

It is a semi-crystalline fluoropolymer (a partly fluorinated polymer), with chemical corrosion resistance properties.

Once a part is rotolined, it cannot be welded without risking damaging the lining.

The lining material chemically bonds to the substrate.

We can line almost any shape and configuration of part, with restrictions being:

The lining is seamless with no gaps – and can flow from inside a part to the sealing surfaces of flanges.

It is possible to line using multiple layers of material.

Rotolined parts use a thermoform material, therefore it is possible to plastic weld parts post-lining – either further fabrication, repairs and etc.

We are restricted with what photos and information we can share due to confidentiality constraints, however, we have been rotolining from quite small parts to large parts for some years.

We have a long term relationship with a major international player in the chemical transportation industry who we provide some large rotolined parts to.

The process itself if not particularly new, however, it is effectively not done elsewhere in Australia, and there are very few companies worldwide doing it – there is some information available via google with better photos than I can provide.

The basic steps of rotolining are:
