Silicone Rubber Supplier in Malaysia
- Also known as
- Silicone Elastomer
- Polysiloxane Rubber
Silicone rubber supplier for moulding, extrusion, sealing, electrical and general manufacturing buyers in Malaysia. Silicone rubber is a family of crosslinkable polysiloxane elastomers, not a single fixed formulation, and the useful buying distinction is the processing form and cure system required by the production line.
Commercial options include high consistency rubber (HCR) supplied as a millable gum, pumpable liquid silicone rubber (LSR), one-part RTV pastes and two-part RTV systems. Peroxide, addition and condensation cure chemistries serve different processing routes, so they should not be substituted on name alone.
Silicone rubber is used for seals, tubing, moulded automotive parts, electrical insulation, potting, flexible moulds, construction sealants and selected healthcare components. Grade selection commonly turns on hardness, viscosity or plasticity, cure profile, colour and the performance requirements of the finished part.
Send the required form, cure system, Shore hardness, processing method, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.
- Grade
- high consistency rubber, liquid silicone rubber, one-part RTV, two-part RTV
- Appearance
- translucent, white or pigmented elastomer supplied as gum, paste, liquid components or cured rubber according to grade
Silicone Rubber 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 |
|---|---|---|---|---|
| High consistency silicone rubber (HCR) | solid gum compound or millable rubber | — | Compression moulding, transfer moulding and extrusion of seals, tubing, profiles and moulded parts. State the cure system, hardness and processing method when requesting a grade. | Confirm the required pack format with the quotation. |
| Liquid silicone rubber (LSR) | pumpable two-component liquid system | — | Injection-moulded seals, electrical parts, precision components and selected healthcare or food-contact articles where an appropriate grade and supporting documentation are specified. | Confirm the component pack format with the quotation. |
| One-part room-temperature-vulcanising silicone rubber (RTV-1) | ready-to-use paste | — | Sealing, gasketing, bonding and protective applications where the material cures after exposure to ambient moisture. | Confirm the required cartridge, pail or other format with the quotation. |
| Two-part room-temperature-vulcanising silicone rubber (RTV-2) | pourable or paste-like base and curing component | — | Flexible moulds, potting, encapsulation and cast elastomer parts where the buyer controls mixing and cure conditions. | Confirm the matched component pack format with the quotation. |
| Peroxide-cure or addition-cure silicone compound | gum or liquid compound according to processing route | — | Industrial moulding and extrusion where the curing chemistry, post-cure requirement and finished-part properties are fixed by the processor. | Confirm the required pack format with the quotation. |

Silicone Rubber applications
Safety and handling
Keep components sealed in a cool, dry place and protect them from moisture, heat and contamination that could interfere with cure. Store multi-component systems separately as directed for the quoted grade and follow its safety information.
Common questions about silicone rubber
Which silicone rubber type should I request?
HCR is a millable gum used for compression moulding and extrusion, while LSR is a pumpable two-component system for injection moulding. RTV-1 is a ready-to-use moisture-curing paste and RTV-2 is mixed before casting, moulding or potting. State your processing equipment and cure method.
Is silicone rubber the same as silicone oil or finished silicone sealant?
No. Silicone rubber is a crosslinkable elastomer family. Silicone oil is a fluid, while a finished sealant is a formulated product containing a silicone binder and other components. Request the actual material and form needed for the process.
What specifications matter when matching a silicone rubber grade?
Buyers commonly compare physical form, cure system, Shore hardness, viscosity or plasticity, colour, cure profile and finished-part properties. Send the current grade sheet or target values with the enquiry.
What is the difference between addition-cure and condensation-cure RTV?
They use different curing chemistries and are not automatically interchangeable. Cure speed, shrinkage, catalyst sensitivity, substrate compatibility and service requirements should be checked against the full formulation before selecting a replacement.
Can food-contact, healthcare or electrical grades be requested?
Yes, but the intended standard and required documents must be stated with the enquiry. The quotation confirms whether a suitable grade, supporting documentation and pack format can be offered.
How do I request a silicone rubber price in Malaysia?
Provide the silicone rubber type, cure system, hardness, colour, processing method, quantity and delivery location. Mention any matched-grade or documentation requirement so the quotation addresses the complete need.
