Rubber Sheeting/Bromobutyl
Bromobutyl Rubber Sheet (Acid Resistant)
Chemical-resistant bromobutyl (BIIR) lining sheet, 50 Shore, for mineral acids, brine and alkaline solutions.

Bromobutyl is the lining compound for chemical service. It resists mineral acids, brine and alkaline solutions that attack natural rubber, and it is rated to 120 °C (not continuous).
Our AU 50 Shore bromobutyl sheet lines acid plants, CIL and CIP tanks and water-treatment vessels. We used it to line an acid wash plant, and we line with it in our workshop or on site as well as supplying the sheet.
Best for: Acid, brine and alkaline service. Not sure which sheet you need? See our full rubber sheeting range or tell us the duty and we will specify the grade and gauge.

Applications
- ▪Acid-service tank linings, including CIL and CIP tanks
- ▪Pickling and process vessels
- ▪Pipes and launders in corrosive duty
- ▪Water-treatment vessels
- ▪Pulleys and hoses
Not recommended for
Oils, greases and some solvents, and heavy abrasion (bromobutyl has limited abrasion resistance). Confirm chemical compatibility before lining.
Thickness guide
| Thickness | Typical use |
|---|---|
| 3mm – 5mm (thin rubber sheet) | Gaskets, wear pads, skirting, light abrasion and lining where weight or clearance matters |
| 6mm | The usual lining gauge for general slurry abrasion in pipes, tanks and cyclones |
| 10mm – 12mm | Pipe bends, reducers and chute impact points where the flow changes direction |
| 15mm – 25mm (heavy rubber sheet) | Heavy impact and wear zones: chutes, hoppers, transfer points and screen decks |
How to order
1
Tell us the duty
Compound or duty, thickness, width and how many rolls. A drawing or the item being lined helps.
2
Get a quote
We quote per compound, thickness and quantity, by the roll or as part rolls and custom widths for smaller jobs.
3
Collect or delivery
Collect from Anderbolt, Boksburg, or delivery across Gauteng, weekly routes into Mpumalanga and freight across Southern Africa.
Every roll leaves the mill labelled with the compound, hardness, thickness and production date for batch traceability. Need the equipment lined too? We do rubber lining in our workshop or on site.
Questions
Why use bromobutyl rubber for acid tanks?+
Bromobutyl has very low permeability and resists mineral acids, brine and alkaline solutions, so it protects the steel behind it where natural rubber would be attacked. It is the standard lining for acid plants and CIL and CIP tanks.
What temperature can bromobutyl rubber sheet handle?+
Our AU 50 Shore bromobutyl is rated to 120 °C, not continuous. Give us the chemical, concentration and temperature and we will confirm it suits your service.
Is the sheet supplied steam-cured or pre-cured?+
Either. Steam-cured (uncured) sheet is for items that are lined and then vulcanised in an autoclave, which gives the strongest bond. Pre-cured sheet is already vulcanised, for lining that cannot go through an autoclave, such as large tanks and on-site work. Tell us how the sheet will be applied and we supply the right cure state.
Can I buy this rubber sheet per metre?+
We sell rubber sheeting by the roll (standard 1200mm × 12m, up to 12.5m long on request), plus part rolls and custom widths for smaller jobs. We do not sell off the roll per metre. Send us the compound, thickness and quantity you need and we will quote.
Where can I collect or get rubber sheet delivered?+
Collect from our Anderbolt, Boksburg facility on the East Rand, or we deliver across Gauteng and on our weekly routes into Mpumalanga, with freight to the rest of South Africa and to Mozambique, Namibia, Zambia, Botswana and Zimbabwe.
