Product Overview

Rubber Antioxidant MBI (2-Mercaptobenzimidazole) | CAS 583-39-1
Professional Non-Staining Secondary Antioxidant and Metal Deactivator for High-Performance Elastomers.

Product Introduction

Rubber Antioxidant MBI (CAS 583-39-1), chemically 2-Mercaptobenzimidazole, is a critical non-staining secondary antioxidant. It functions as a hydroperoxide decomposer, significantly enhancing the thermal stability of rubber compounds when paired with primary antioxidants. Its unique ability to inhibit copper-catalyzed oxidation makes it the gold standard for electrical wire insulation and automotive seals. It is completely non-staining, ensuring aesthetic integrity in white or translucent rubber products.

Product Advantages

High Purity (≥ 290.0 °C melting point) ensures no blooming or curing interference
Superior Metal Deactivation: Specifically designed to stop copper ion-induced aging
Multiple Physical Forms: Powder, Oiled Powder, and 2.5mm Granules available for optimized handling
Excellent Synergy: Provides enhanced protection when used with phenolic or amine antioxidants

Basic Physical Properties

CAS Number	583-39-1
Chemical Formula	C7H6N2S
Molecular Weight	150.2
Appearance	White powder or granule

Technical Specifications

Test Item	Standard Spec	Actual Result
Initial Melting Point	≥ 290.0 °C	290.4 °C
Loss on Drying	≤ 0.30%	0.12%
Ash Content	≤ 0.30%	0.11%

Industrial Applications

Electrical Wire & Cable Insulation
Protects the rubber sheath from oxidation caused by contact with copper conductors.

Automotive Heat-Resistant Parts
Extends the life of EPDM seals, radiator hoses, and gaskets in engine compartments.

White & Light-Colored Footwear
Ensures premium soles stay white and don't crack due to heat or environmental aging.

Industrial Belting
Used in conveyor belts and transmission belts to maintain tensile strength under high friction.

Packaging & Logistics

Packed in 25kg multi-layer paper bags with PE liner. 10-12 MT per 20'FCL with pallets. Non-hazardous. Store in cool, dry conditions; shelf life 24 months.

Synonyms

2-Mercaptobenzimidazole, Antioxidant MB, Antioxidant MBI, Benzimidazole-2-thiol.

Synergistic Matching Materials

Antioxidant 2246 (CAS 119-47-1)
Antioxidant 6PPD (CAS 793-24-8)
Antioxidant RD (TMQ) (CAS 26780-96-1)
Zinc Oxide (CAS 1314-13-2)
EPDM Rubber (CAS 25038-36-2)
Accelerator TMTD (CAS 137-26-8)
Chloroprene Rubber (CR) (CAS 9010-98-4)

Frequently Asked Questions

How does MBI function differently from 6PPD?

6PPD scavenges free radicals but stains; MBI decomposes hydroperoxides and is non-staining.

Why use the Oiled Powder version?

It significantly suppresses dust, improving factory safety and material usage efficiency.

Does MBI interfere with vulcanization?

It can mildly retard cure speed; it is recommended to monitor T90 times with a rheometer.

Why is MBI called a Metal Deactivator?

It complexes with copper ions, preventing them from catalyzing rubber degradation.
