Built to take the abrasion
so your equipment lasts longer
Rubber wear liners and skirting rubber for chutes, hoppers and conveyor transfer points — manufactured in Thailand to ISO 9001:2015 standard, backed by full batch traceability and fixed pricing for up to 24 months.
Every tonne through the chute takes a little steel with it
Ore, slurry and bulk product don't just pass through a chute or over a transfer point — they grind against it. Left unprotected, that abrasion eats into structural steel until a hopper wall thins out, a chute wears through, or a conveyor skirt stops sealing and starts spilling product onto the ground.
A wear liner or a strip of skirting rubber is a sacrificial layer, designed to take that abrasion in your place and be replaced on a schedule you control — instead of steel failing on a schedule it controls.
Three products, one job: protect what's underneath
All three are ordered against the same quality framework — full material traceability, batch rheometer data and a Certificate of Analysis with every shipment.
Natural Rubber Wear Liners
- Chute walls, hopper linings, launders and transfer point walls
- Natural rubber (NR) sheet, 6–60mm, cut and edge‑prepared to your drawings — the baseline for most wear liner orders
- NBR, CR and EPDM grades available where oil, chemical, or UV exposure is the driver rather than pure abrasion
- Specialty compounds available on request — BR, FKM (Viton) and Hypalon (CSM) for extreme heat, chemical, or weathering service outside standard duty
- Supplied loose for field bonding or pre‑bonded to steel backing plates
- 2‑year product warranty
Ceramic‑Rubber Hybrid Panels
- For high‑velocity or sharp‑ore zones where straight rubber wears fastest — chute knuckles, transfer point impact zones and high‑abrasion launders
- Ceramic tile vulcanisation‑bonded to an 8–20mm rubber backing, press‑formed as panels
- Tile hardness from roughly 950 up to 1,200 HV depending on grade — harder than hardened steel — matched to the abrasion severity of your application. Silicon Carbide (SiC) available on request for extreme thermal or chemical service
- Large wear areas engineered as a tiled multi‑panel layout — panel size is set by press capacity, not by what we can cover
- Panel layout, joint pattern and backing plate design engineered to your chute or hopper drawing
- Project-specific warranty — see Section 7 for scope
Conveyor Skirting Rubber
- Seals loading and transfer points to contain fines and dust and stops spillage building up under the belt
- Standard NR / NR‑SBR compounds, 10–25mm, slit and edge‑profiled to your skirt geometry
- Softer 50–60 Shore A grades available where protecting the belt edge matters more than raw abrasion resistance
- FRAS‑capable compound development (AS 4606, AS 1334.10, TRG 3608) for underground and coal handling duty — see Fire Resistant + Anti‑Static Compounds section
- Supplied in coil or cut length, with or without pre‑drilled mounting holes
Comparison — at a glance. Not sure which one your drawing needs? Here's the quick comparison.
| Consideration | Natural Rubber Liner | Ceramic‑Hybrid Panel |
|---|---|---|
| Best for | General abrasion — chute walls, hoppers, launders | High‑velocity impact and sharp‑ore zones where straight rubber wears fastest |
| Construction | NR sheet, 6–60mm, direct or field‑bonded | Ceramic tile vulcanisation‑bonded to 8–20mm rubber backing, press‑formed panels |
| Install format | Cut and edge‑prepared to drawing, supplied loose or pre‑bonded to steel | Modular panels tiled to a layout engineered from your drawing — joint pattern and backing plate design included |
| Relative cost | Lower unit cost | Higher unit cost, offset by extended wear life in the zones that fail fastest |
| Warranty | 2‑year product warranty | Project-specific warranty |
Underground and hazardous‑area installations don't run on one global spec — each market enforces its own fire‑resistant and anti‑static requirement, with its own test methods and its own certifying body.
| Market | Governing standard(s) |
|---|---|
| Australia / NZ | FRAS: AS/NZS 4606 (fire) and AS 1334.10 (electrical resistance), administered under TRG 3608 and state mining regulator frameworks |
| USA | MSHA: 30 CFR Part 14 flame‑resistance approval for underground coal mine belting, typically paired with ASTM D257 electrical resistance testing for anti‑static performance |
| Canada | CSA M422: a single standard covering both fire‑performance and antistatic requirements for underground mining and excavation belting — distinct from the US MSHA system |
| Europe | EN 14973 / EN 12882: underground and above‑ground conveyor safety standards respectively, both built on ISO 340 (flame) and ISO 284 (antistatic) test methods |
| Middle East / UAE | No independent domestic standard — compliance is specified against whichever recognised international standard the project calls for, most often the Australian or European frameworks above |
We are fully capable of developing rubber compounds to meet all the standards above. Formal third‑party testing and certification will be arranged on a per‑project basis to the exact standard your site requires. We recommend discussing your specific requirements early so the appropriate formulation and testing timeline can be built into your project schedule.
Match the right rubber compound to the real wear mechanism
Straight abrasion, impact, ozone, UV, oil and chemicals all attack rubber differently. We select the base polymer and additives based on your specific failure mode.
| Compound | Hardness | Best suited to |
|---|---|---|
| NR | 40–80 Shore A | General‑purpose wear liners — the baseline for chute and hopper linings where abrasion resistance is the priority |
| NR / SBR | 50–70 Shore A | Skirting rubber and moderate‑duty liners where cost efficiency matters alongside wear life |
| EPDM | 40–90 Shore A | Outdoor stockpiles and conveyor runs exposed to ozone, UV and weathering |
| NBR | 50–90 Shore A | Petrochemical and mineral processing chutes with oil or hydrocarbon exposure |
| CR | 40–90 Shore A | General industrial duty needing moderate chemical and weather resistance |
| Butyl | Wide range | Low‑permeability linings for chemical containment applications |
What's between the ore and steel
Hover any layer in the diagram for what it does and why it's there.
Rheometer testing runs on every batch. The rest run against the standards below, with results issued as part of the shipment's Certificate of Analysis.
DIN Abrasion Resistance
Target under 120 mm³ loss for premium grades — the core measure of how long a wear liner actually lasts.
Tear Strength
Resistance to tearing once a nick or cut starts — critical at liner edges and bolt‑hole penetrations.
Tensile Strength & Elongation
Confirms the compound holds together and flexes as specified under load.
Hardness (Shore A)
Verifies the durometer ordered is the durometer delivered, batch to batch.
Specific Gravity / Density
Flags compound substitution or filler loading that would otherwise go unnoticed.
Rheometer — Cure Curve
Run on every batch to confirm consistent cure state before it ever reaches your site.
Ozone & UV Weathering
Confirms outdoor stockpile and conveyor installations won't crack and perish prematurely.
Oil & Chemical Resistance
Confirms swell and degradation stay within spec for petrochemical and processing environments.
Bond Strength
Run on ceramic‑hybrid and laminated builds — a wear system is only as good as its weakest bond.
SGS pre‑shipment inspection
Independent verification before your order leaves Thailand.
Full batch traceability
Back to the raw rubber lot, with a Certificate of Analysis issued for every shipment.
Certificate of Origin
Issued by Duratan as exporter of record. This supports preferential duty treatment for imports into Australia (TAFTA), New Zealand, Japan, China, South Korea and other Free Trade Agreement partner countries.
Fixed pricing, up to 24 months
Hedged against raw rubber, foreign exchange and freight volatility.
2‑year warranty
Natural rubber wear liners and skirting rubber.
Project-Specific Warranty
Ceramic-rubber hybrid panels, with warranty terms based on the application, operating conditions and project requirements, including tile-to-rubber bond integrity.
