Isobutylene Supplier in Malaysia
- Also known as
- Isobutene
- 2-Methylpropene
Isobutylene supplier enquiries in Malaysia cover polymerisation, technical and high-purity requirements for this branched C4 alkene. Also called isobutene or 2-methylpropene, isobutylene has the formula C4H8 and CAS 115-11-7.
Polymerisation grade isobutylene is used as a monomer feed for polyisobutylene, butyl rubber and related elastomer processes. Technical grade serves defined petrochemical and chemical manufacturing duties, while high-purity material is selected against tighter impurity limits.
Isobutylene is a colourless gas at ambient conditions and is commonly handled as a liquefied gas under pressure. It must be distinguished from 1-butene, polyisobutylene, butyl rubber and raffinate-2 because those are separate products with different specifications and uses.
Send the required grade, composition limits, quantity, receiving capability and delivery location with your enquiry. Availability, supply format, documentation, route and timing are confirmed with the quotation, and supply is subject to applicable requirements.

Isobutylene grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Polymerisation grade isobutylene | liquefied gas under pressure | — | Reactive C4 monomer feed for polyisobutylene, butyl rubber and other polymerisation processes where the receiving plant sets composition and impurity limits. | Supply format and pressure-service arrangement confirmed with the quotation. |
| Technical grade isobutylene | liquefied gas under pressure | — | Petrochemical intermediate for downstream chemical manufacture, blending or process use where a defined isobutylene content is required. | Supply format and pressure-service arrangement confirmed with the quotation. |
| High-purity isobutylene | liquefied gas under pressure | — | Controlled process or specialty synthesis feed where tighter limits for moisture, other C4 hydrocarbons and non-condensable impurities are specified. | Supply format and pressure-service arrangement confirmed with the quotation. |

Common questions about isobutylene
What is isobutylene also called?
Isobutylene is also called isobutene and 2-methylpropene. The product identity is CAS 115-11-7 and the molecular formula is C4H8.
Is isobutylene the same as 1-butene?
No. Isobutylene and 1-butene are different C4 alkene isomers with different structures and process behaviour. Specify the required isomer because one is not a substitute for the other in a polymer or chemical process.
Which isobutylene grade should I request?
Polymerisation grade suits polyisobutylene and butyl rubber feed. Technical grade covers defined petrochemical and process requirements, while high-purity material is selected when tighter moisture or hydrocarbon impurity limits apply. Send the receiving specification with the enquiry.
Is isobutylene a gas or a liquid?
Isobutylene is a gas at ambient conditions and is commonly handled as a liquefied gas under pressure. State the receiving interface, quantity and preferred supply arrangement so the quotation can address the actual process.
Is isobutylene the same as polyisobutylene or butyl rubber?
No. Isobutylene is the small-molecule C4 monomer, polyisobutylene is its homopolymer, and butyl rubber is an isobutylene-based copolymer elastomer. They are separate products and should be ordered by the exact material name.
What details are needed for an isobutylene price quotation?
Provide the grade, composition or impurity limits, downstream application, required quantity, receiving capability and delivery location. Include any documentation or transfer requirements so the commercial format can be confirmed with the quotation.
