ESD Rubber Bands
Malaster ESD rubber bands provide reusable, adhesive-free retention for IC shipping tubes, JEDEC trays, protective boxes, component kits, and other static-sensitive packaging. Available as pink MC-ASRB and black MC-CRB product families, both provide static-dissipative performance through different constructions and controlled resistance ranges.
Black ESD bands are also commonly searched for as conductive rubber bands. Learn how the terminology differs from the current classification →
Choosing the Right ESD-Safe Rubber Band
Malaster ESD rubber bands provide reusable, adhesive-free retention for
IC shipping tubes,
JEDEC trays,
protective boxes, component kits, and other static-sensitive packaging during handling, storage, and shipment.
Pink MC-ASRB and black MC-CRB rubber bands are available in multiple sizes. Both families provide static-dissipative performance, but their construction and controlled surface-resistivity ranges are different. Selection should be based on the device, intended contact, packaging system, grounding conditions, and applicable ESD-control requirements.
Pink ESD-Safe Rubber Bands
Surface-treated natural-rubber bands providing low-charging, static-dissipative performance for general component retention and ESD packaging applications.
1 × 108 to 1 × 1010 Ω/square
Black ESD-Safe Rubber Bands
Impregnated natural-rubber bands providing a lower controlled surface-resistivity range when lower-resistance static-dissipative performance is specified or preferred.
1 × 104 to 1 × 106 Ω/square
Pink and Black ESD Rubber Band Comparison
| Band Family | Construction | Classification | Surface Resistivity | Selection Guidance |
|---|---|---|---|---|
| Pink MC-ASRB | Surface-treated natural rubber | Static dissipative and low charging | 1 × 108 to 1 × 1010 Ω/square | General reusable bundling and retention for IC tubes, trays, protective boxes, packaging, and static-sensitive components. |
| Black MC-CRB | Impregnated natural rubber | Static dissipative | 1 × 104 to 1 × 106 Ω/square | Applications where a lower-resistance static-dissipative retention band is specified or preferred. |
Lower electrical resistance does not automatically make one band better for every application. Product selection should consider the complete packaging system and the customer’s ESD-control requirements.
The black MC-CRB family is often searched for and historically described as conductive rubber bands. Malaster retains the MC-CRB identifier for continuity with purchasing records, drawings, approved material lists, and historical specifications. Current controlled product data classifies these bands as static dissipative.
Material data sheets, controlled resistance information, size guidance, and supporting RoHS and REACH documentation are available from Malaster.

Why Choose Malaster ESD Rubber Bands?
Malaster has decades of experience supplying ESD-safe packaging products to semiconductor manufacturers, electronics assemblers, aerospace contractors, medical-device companies, and other operations handling static-sensitive components.
ESD rubber bands provide temporary, reusable retention without the adhesive residue associated with tape or the cutting and replacement required with single-use cable ties. Bands that remain in acceptable condition can be removed and reapplied as packaging moves through manufacturing, inspection, inventory storage, and shipment.
ESD-Controlled Handling
Pink MC-ASRB and black MC-CRB options support component handling and packaging within an established ESD-control program.
Reusable Retention
Secure packaging without adhesive residue. Serviceable bands can be removed and reapplied during handling, inspection, storage, and shipment.
Multiple Sizes
Multiple lengths and widths support IC tube bundles, JEDEC tray stacks, protective boxes, clamshells, component kits, and other packaging configurations.
Technical Support
Material data sheets, controlled resistance information, size guidance, and supporting RoHS and REACH documentation are available.
Common Uses for ESD Rubber Bands
ESD rubber bands are used where static-sensitive products or packaging require temporary retention, organization, or closure without relying on tape or conventional office rubber bands.
Packaging, Storage, and Inspection
Standard Packaging
Bands are packaged by weight in polyethylene bags containing 1 kilogram, approximately 2.2 pounds, of product. Piece counts are approximate and vary by band dimensions and normal manufacturing and weight tolerances.
Storage Guidance
Keep bands in their original packaging until needed and reseal opened packages when practical. Protect them from sunlight, ultraviolet exposure, excessive heat, ozone-producing equipment, oils, solvents, contamination, and prolonged storage under stretch or compression.
Planning Guidance After Opening
Plan to use pink MC-ASRB and black MC-CRB bands within 9 to 12 months after opening. Apply first-in, first-out inventory practices. These intervals are conservative planning guidance, not guaranteed failure dates.
