Polyisobutylene (PIB) Supplier in Malaysia
- Also known as
- PIB
- Polyisobutene
- Isobutylene Polymer
Polyisobutylene supplier for adhesive, sealant, lubricant-additive and film manufacturers in Malaysia. Polyisobutylene, usually shortened to PIB, is a homopolymer of isobutylene with a saturated backbone and a strongly hydrophobic character. Molecular weight is the single axis that decides the grade, so the material runs from a viscous tacky liquid to a rubbery solid.
Low molecular weight grades are liquid and go into pressure-sensitive adhesives, sealant plasticisers and lubricant or fuel additive packages. Medium grades are tacky semi-solids used in construction and insulating-glass sealants and in cable compounds. High molecular weight grades are solid bales for sealants, cling and stretch film modification and rubber compounding.
Grade codes differ between producers, so the practical route is to state the molecular weight band or the grade already in use. Butyl rubber, the isobutylene-isoprene copolymer, is a separate curable elastomer and is not a grade on this page. Polybutene, a mixed-butene liquid polymer, is also a different product.
Send the required molecular weight band, application, target specification, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation. Supply is subject to applicable requirements.

Polyisobutylene 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 |
|---|---|---|---|---|
| Low molecular weight polyisobutylene | viscous tacky liquid | — | Pressure-sensitive adhesive tackifier, sealant plasticiser and base polymer for lubricant and fuel additive packages, where a pumpable liquid is needed. | Pack format confirmed with the quotation. |
| Medium molecular weight polyisobutylene | tacky semi-solid mass | — | Construction and insulating-glass sealants, cable and wire compounds and hot-applied formulations that need more body than a liquid grade gives. | Pack format confirmed with the quotation. |
| High molecular weight polyisobutylene | rubbery solid bale | — | Sealant and compounding elastomer, cling and stretch film modification and rubber compounding where a solid, non-curable isobutylene polymer is specified. | Compressed bale in polyethylene film; pack format confirmed with the quotation. |

Specifications
| Parameter | Value | Method |
|---|---|---|
| Polymer type | homopolymer of isobutylene, saturated hydrocarbon backbone | — |
| Appearance | colourless to pale, tacky liquid through to rubbery solid according to grade | — |
| Grade axis | molecular weight band, confirmed against the buyer's grade code or target viscosity specification | — |
| Cure behaviour | essentially saturated, so it is used as a tackifier and viscosity modifier rather than a sulphur-vulcanised elastomer | — |
| Solubility character | hydrophobic and non-drying; typically compatible with mineral oils and many hydrocarbon media | — |

Safety and handling
Store in closed containers in a cool, dry place away from strong oxidising agents and ignition sources. Follow the safety information supplied with the quoted grade.
Common questions about polyisobutylene
What does PIB stand for and is it the same material?
PIB is the trade abbreviation for polyisobutylene, so the two terms describe the same isobutylene homopolymer. Buyers also write polyisobutene or isobutylene polymer on specifications.
Which molecular weight grade of polyisobutylene should I request?
Molecular weight is the decision axis. Low grades are liquid and suit adhesive tackifiers, sealant plasticisers and lubricant additives, medium grades are tacky semi-solids for sealants and cable compounds, and high grades are solid bales for film and rubber compounding. State the grade code you use or the target viscosity and application.
Is polyisobutylene the same as butyl rubber?
No. Polyisobutylene is a saturated homopolymer of isobutylene used as a tackifier, sealant polymer and viscosity modifier, while butyl rubber is the isobutylene-isoprene copolymer that is compounded and vulcanised. Request each one under its own identity so the correct chemistry is quoted.
Is polyisobutylene the same as polybutene?
No. Polybutene is a liquid polymer of mixed butenes with its own viscosity grade range, while polyisobutylene is polymerised from isobutylene alone. Both work as tackifiers, so name the one your formulation specifies.
What is low molecular weight polyisobutylene used for?
Liquid grades go into pressure-sensitive adhesives and tapes, sealant and caulk formulations, cable filling compounds and the manufacture of lubricant and fuel additives. Describe the end use when enquiring so the grade discussion stays practical.
How is polyisobutylene priced and quoted in Malaysia?
Price depends on the molecular weight grade, specification, packing and quantity. Send those details with the delivery location and any document requirements for a quotation with a stated validity period.
