Product Overview

What is Butyl Rubber (IIR)?

Butyl Rubber (IIR) is a synthetic elastomer produced by cationic copolymerisation of isobutylene with a small proportion of isoprene (typically 0.5–2.5 mol%). The near-saturated backbone gives butyl rubber the lowest gas and moisture permeability of any commercial elastomer, along with excellent resistance to ozone, weathering, acids, alkalis and polar solvents.

Because the isoprene content is so low, butyl rubber is dramatically slower to cure than general-purpose rubbers, but this same saturated structure is what makes it chemically inert and dimensionally stable over long service life — which is why it dominates tyre inner-liner, pharmaceutical closure and sealant applications worldwide.

Halogenated variants — chlorobutyl (CIIR) and bromobutyl (BIIR) — offer faster, more compatible cure with general-purpose rubber compounds while retaining butyl's core impermeability advantage, and are the standard for modern radial tyre inner liners. Chelora Chemicals UAE stocks both regular and halobutyl grades for compounders and industrial converters across the region.

Applications

Key Applications of Butyl Rubber (IIR)

Butyl rubber's unmatched impermeability and chemical inertness make it indispensable wherever gas-tightness, pharmaceutical purity or vibration damping are required.

Tyre Inner Liners & Inner Tubes

Halobutyl (CIIR/BIIR) grades are the global standard for radial tyre inner liners, retaining air pressure far longer than any alternative elastomer, while regular butyl remains the material of choice for bicycle and heavy-vehicle inner tubes.

Pharmaceutical Stoppers & Closures

Chemically inert, low-extractable butyl formulations are used for vial stoppers, syringe plungers and IV-bag closures, protecting drug formulations from moisture ingress and gas exchange over long shelf lives.

Sealants & Adhesives

Butyl rubber is a key tackifying and sealing component in construction sealants, double-glazing spacer sealants, roofing membranes and pressure-sensitive adhesive tapes used across the UAE's building sector.

Anti-Vibration & Damping Mounts

High damping characteristics make butyl rubber ideal for engine mounts, machinery isolators and vibration-dampening components in industrial and automotive applications across the Gulf.

Chemical-Resistant Linings

Tank linings, hose linings and protective coatings for storage and transport of acids, alkalis and other aggressive chemicals, where resistance to corrosive attack and permeation is essential.

Curing Bladders & Diaphragms

Tyre-curing bladders, autoclave diaphragms and steam-resistant components that must withstand repeated high-temperature cycling while retaining dimensional stability over thousands of cure cycles.

FAQ

Frequently Asked Questions — Butyl Rubber UAE

What is Butyl Rubber (IIR) used for?

Butyl Rubber (IIR) is used primarily for tyre inner liners and inner tubes, pharmaceutical vial stoppers and syringe plungers, construction and glazing sealants, anti-vibration mounts, chemical-resistant tank linings and tyre-curing bladders. Its unmatched gas and moisture impermeability makes it the standard elastomer wherever gas-tightness or chemical inertness is critical across the UAE and GCC.

What is the CAS number of Butyl Rubber?

The CAS number for Butyl Rubber (IIR, Isobutylene-Isoprene Rubber) is 9010-85-9. Halogenated variants — chlorobutyl (CIIR) and bromobutyl (BIIR) — carry their own distinct CAS numbers, so always specify the exact grade when ordering.

What is the difference between regular and halobutyl rubber?

Regular butyl rubber cures slowly and is largely incompatible with general-purpose rubber compounds during co-curing. Chlorobutyl (CIIR) and bromobutyl (BIIR) are produced by halogenating the isoprene double bonds, which dramatically speeds up cure rate and improves co-vulcanisation with natural and SBR rubber — making halobutyl the standard choice for modern tyre inner liners bonded to the tyre carcass.

Who supplies Butyl Rubber in the UAE?

Chelora Chemicals UAE is a dedicated Butyl Rubber (IIR) supplier serving all seven UAE emirates. We stock regular and halobutyl grades in standard bale form, serving the tyre, pharmaceutical, construction, automotive and chemical processing industries across Dubai, Abu Dhabi, Sharjah, Ajman, Ras Al Khaimah, Fujairah and Umm Al Quwain.

Do you deliver IIR to Dubai, Abu Dhabi and Sharjah?

Yes. Chelora Chemicals UAE delivers Butyl Rubber to all seven UAE emirates — Dubai (including Jebel Ali FZ, Al Quoz and DIP), Abu Dhabi (Musaffah, ICAD, KIZAD), Sharjah (SAIF Zone, Hamriyah FZ), Ajman, Ras Al Khaimah, Fujairah and Umm Al Quwain — as well as to Saudi Arabia, Qatar, Kuwait, Bahrain, Oman and other GCC countries.

Why is Butyl Rubber used for pharmaceutical stoppers?

Butyl rubber's near-saturated chemical structure makes it exceptionally inert, with very low levels of extractable compounds that could migrate into drug formulations. Combined with outstanding moisture and gas barrier properties, this makes it the preferred elastomer for vial stoppers, syringe plungers and closures that must preserve sterility and drug stability over extended shelf life, including after steam autoclave sterilisation.

Is Butyl Rubber resistant to chemicals?

Yes. Butyl rubber offers excellent resistance to dilute acids, alkalis, polar solvents (alcohols, ketones), ozone and weathering. It is not recommended for aromatic or aliphatic hydrocarbons, oils and fuels, where swelling occurs — for those applications NBR or FKM would be preferred instead.

What packaging is available for Butyl Rubber?

Chelora Chemicals UAE supplies Butyl Rubber in 25 kg polyethylene-wrapped bales (standard for compounders), 500 kg stretch-wrapped pallet packs, and bulk 20–25 MT Full Container Load (FCL) for large-volume buyers and export. Talc-dusted bales for anti-sticking in high-ambient-temperature environments can be arranged on request.

Can Butyl Rubber be exported from the UAE?

Yes. Chelora Chemicals UAE regularly exports Butyl Rubber to Saudi Arabia, Qatar, Kuwait, Bahrain, Oman and wider markets across Asia, Africa and Europe, leveraging our proximity to Jebel Ali Port. We handle all export logistics including freight forwarding, customs documentation, certificate of origin (COO) and safety data sheets in Arabic and English.
