01 · LINING & SKIRTING
Rubber Lining and Conveyor Skirting,
Cut to Your Drawing.
Abrasion-resistant sheet lining for chutes, hoppers, tanks, sumps and pump casings, and skirting cut to length for conveyor load points — in the same compounds we mix for moulded components, at our ISO 9001:2015 plant in Nashik. Natural rubber has the best abrasion resistance of the eight, and on a lining that is usually the whole specification.

02 · APPLICATIONS
Where the Wear Happens
Lining is not a coating. It is a wear part in sheet form, sacrificial by design, sized so it fails before the steel does and can be replaced without taking the structure apart.
Chutes and transfer points
Impact and sliding abrasion in one place, usually with the worst duty at the impact zone and lighter wear downstream. Lined in soft natural rubber, thickest where the material lands.
Hoppers and bins
Sliding abrasion over large flat areas, plus the build-up problem. A resilient lining sheds material that a steel wall holds.
Pump casings and sumps
Slurry duty, where the lining protects the casing and the moulded wear components protect the flow path. We supply both halves.
Tanks and vessels
Chemical and abrasion protection for process tanks, in EPDM for water, dilute acids and alkalis, or natural rubber where the duty is abrasive rather than aggressive.
Pipework and bends
Bends wear first and wear unevenly. Lined sections are replaced on a schedule instead of the pipe run being rebuilt.
Conveyor skirting and dust curtains
Strips that seal the gap between the belt and the skirtboard at load points, containing fines and dust. Cut to length, softer than the belt cover by design. See section 05.
03 · SPECIFICATION
Thickness Is a Wear-Life Decision
| Duty | Thickness | Hardness | Typical use |
|---|---|---|---|
| Light sliding abrasion | 6 – 8 mm | 55 – 65 Shore A | Hopper walls, launders, low-drop transfer |
| General abrasion | 10 – 12 mm | 45 – 60 Shore A | Chute bodies, pipework, sumps |
| Impact and abrasion | 15 – 25 mm | 35 – 45 Shore A | Impact zones, crusher discharge, high-drop transfer |
| Chemical, non-abrasive | 6 – 10 mm | 60 – 70 Shore A | Tanks and vessels in water and dilute chemistry |
| Conveyor skirting | 6 – 25 mm | 40 – 60 Shore A | Cut to length, see section 05 |
Send the surface area and the duty — what the material is, how far it drops, and how abrasive it is. A drawing or a development helps but is not needed to quote. If you are replacing an existing lining, tell us how long the last one lasted; that single number sizes the next one better than any specification.
04 · COMPOUND
Abrasive or Aggressive? They Need Different Rubber.
Every compound we mix is available as sheet. These are ranked for lining — and unlike every other page in this catalogue, the answer here is usually the cheapest one on the list.
| If the duty is | Compound | Service temperature | Note |
|---|---|---|---|
| Abrasion, impact, slurry — the standard lining duty | Natural rubber | −20 to +90 °C | The default, and the best abrasion resistance of the eight. Soft grades for impact, harder for sliding wear. No oil contact |
| Abrasion at lower cost, dry duty | SBR | −30 to +100 °C | Close to natural rubber in sliding abrasion, cheaper, less resilient under impact. No oil contact |
| Water, steam, dilute acids and alkalis, outdoor | EPDM | −40 to +140 °C | The default for tanks and water service. Excellent ozone and weathering. Never in oil or fuel |
| Oil, fuel or grease contamination in the stream | NBR | −30 to +120 °C | Where natural rubber and SBR would swell. Lower abrasion resistance than either — a trade you make only when you must |
| Marine, moderate oil, flame-retardant grades | Neoprene | −40 to +120 °C | The general-purpose compromise, and the usual answer where a fire rating is specified |
| Aggressive chemistry, solvents, hot service | FKM | −20 to +250 °C continuous to +200 °C | Available as sheet and rarely justified — at lining areas the cost is significant. Specify it on the medium, not on the temperature alone |
| Hot oil and oil mist | AEM | −40 to +175 °C continuous to +160 °C | Rarely a lining duty. Listed because every compound is available |
| Clean, high-temperature, non-abrasive | Silicone | −60 to +220 °C | Not a lining compound. Low tear strength and poor abrasion resistance — the two properties a lining exists to provide. Available, and almost never right |
05 · SKIRTING
Skirting Should Wear Out Before Your Belt Does
Skirting seals the gap between the belt and the skirtboard at a load point, containing fines and dust where the material lands. It has to be softer than the belt’s top cover. A skirting strip harder than the cover does not wear — the belt does, and a grooved belt costs several orders of magnitude more than the strip that grooved it. We supply skirting at 40 to 60 Shore A for that reason, and we will ask what belt you are running before we quote a hardness.
| Item | Range | Note |
|---|---|---|
| Thickness | 6 – 25 mm | Set by the skirtboard clamp and the gap |
| Width | 100 – 300 mm | Cut to your skirtboard. Allow for the wear length, not just the seal |
| Hardness | 40 – 60 Shore A | Softer than the belt top cover. Tell us the belt grade |
| Compound | Natural rubber · SBR | Natural rubber for abrasive fines, SBR where cost governs |
| Supply | cut to length | Quoted against total metreage, not per piece |
| Also supplied | dust curtains · chute seals | Same compounds, same sheet, cut to your opening |
We supply skirting rubber and dust curtain sheet. We do not supply skirtboard steelwork, clamps or sealing systems.
06 · TESTING
We Can Put a Number on the Abrasion
Abrasion resistance is measured as volume loss to ISO 4649 (equivalently ASTM D5963) — a rotating drum test that reports how many cubic millimetres a standard specimen loses over a fixed path. Lower is better, and it is the one number that ranks lining compounds meaningfully. We report it on the compound supplied, per batch, rather than publishing a figure here — a headline number belongs to a specific formulation, and quoting one on a category page is how a buyer ends up designing around a compound they were never sent.
| Property | Method | Where |
|---|---|---|
| Abrasion loss | ISO 4649 · ASTM D5963 | NABL partner laboratory |
| Hardness | ASTM D2240 | In-house |
| Tensile and elongation | ASTM D412 | In-house |
| Tear strength | ASTM D624 | NABL partner laboratory |
| Fluid immersion / volume swell | ASTM D471 | NABL partner laboratory |
| Ozone resistance | ISO 1431-1 | NABL partner laboratory |
| Adhesion to steel | ASTM D429 · failure mode to 100% R | See sheet 37 |
| Wear life in service | — | not predictable from a test |
Material test reports, dimensional inspection sheets and a certificate of conformance ship with every consignment. Batch records are retained per shipment and are available on request under NDA. Sheet is rolled and packed so the bonding face is not contaminated in transit.
Supplied Cut, or Supplied and Fitted
Lining is supplied cut and prepared to your development, or supplied and fitted — tell us which when you enquire, because it changes the specification as well as the price. A fitted lining is bonded to prepared steel; a supplied one arrives ready for your applicator’s system.
Where we fit, the steel is degreased and grit-blasted to a controlled profile before priming, and the lining is bonded within a defined window before the surface re-oxidises — the same discipline described on our bonded components page, at a larger scale.
